When the Dura-Ace 7800 group was introduced for the 2004 season, it didn’t feature a hint of carbon fiber despite the fact that Campagnolo was offering ample amounts of the material throughout its flagship Record group. At the time Shimano relied on its ability to forge high quality aluminum at its Osaka factories. Four years later, carbon fiber is quite evident in Shimano's 2008 line. Four of Dura-Ace’s five wheel models feature carbon fiber rims, while a fifth uses scandium. The just released XTR Shadow rear derailleur sports a true carbon fiber pulley cage. And to put the icing on

Photo Gallery Below On a day when I pause every year to reflect on what the future may holdfor all of us, I think about the things that give me a little hope forthat future. One of those things is seeing kids on bikes. The future seems a lotbrighter to me if lots of kids are riding bikes, ensuring a healthier nextgeneration of adults treading more lightly on the earth with another toolto combat global warming and oil dependence. There are a number of great programs around the country that are successfulin creating passionate young bike riders, and I think all of them shouldbe encouraged. I

Unlike Interbike in the United States, Eurobike’s final day is open to the public. Anyone with 20 extra euros can show up at the Messe Friedrichshafen and see the bicycle industry’s best. Because of this, most of the show's business is done by Saturday afternoon, freeing exhibitors from spec’ and sales meetings, plus the press, just in time to be thrown to an inquisitive public. We saw a lot on Saturday, some of which can be quickly explained and some that will require more attention. Over the next few weeks, in a lead-up to Interbike, we will try to explore in detail some of those

If the scale of parking problems are an indication of interest, then Eurobike qualifies as a success. The line just to park at the Messe Friedrichshafen on the second day of the trade show was an hour long. Bumper-to-bumper traffic, all of it bound for Eurobike. The show, held on Germany’s southern border, attracts exhibitors from more than 36 countries — and that includes everyone, from the biggest players to the most obscure little guys. Here’s what caught our attention on Friday. LightweightThe famous German Lightweight wheels have a new look these days. The new black all-carbon spokes

Once home to the early 20th century’s famous Graf Zeppelin factory, the southern German town of Friedrichshafen now plays host to retirees and tourists visiting Lake Constance and – once a year – to what is becoming one of the world’s biggest bicycle industry trade shows. Thursday marked the opening of the 16th Eurobike show, with more than 850 exhibitors from 36 countries showing their wares in an astounding 13 exhibition halls. Despite the ample space, navigating the aisles was already tough Thursday — and that’s before the show opens to the general public on its final day on

SRAM finally unveiled its top-of-the-line component group last month. The company outlined details of the "Red" group during the Tour de France, where the group - still in prototype - saw action. Now, on the eve of the industry tradeshow season’s start, at Eurobike in Friedrichschafen, Germany, SRAM introduced a round of ready-to-ride pre-production parts, manufactured on the line's final tooling. Red’s specifications were finalized in conjunction with SRAM’s entry into the ProTour, by means of its sponsorship of Saunier Duval-Prodir. The relationship proved challenging to say the

Predictor-Lotto star Cadel Evans came within a scant 23 seconds of winning this year’s Tour de France and narrowly held on to second place, a mere eight seconds ahead of third-place Levi Leipheimer. It’s fair to say that Evans’ podium performance is thanks in part to his two breakthrough time trial rides. Evans placed second in both long time trials, behind Alexandre Vinokourov in stage 13 and behind Leipheimer in stage 19. With final time differences that slim, it is interesting to look at small time contributions among the top three riders overall, especially in long time trials, where

Dear Lennard,Was there any official report as to why David Millar's rear wheel fellapart during the stage 19 time trial at the Tour de France. I have neverseen anything like that. He seemed to have multiple wheels with the sameproblem right up to his mechanic riding a new bike out to him. How weirdwas that?Christopher Dear Christopher,Yes, I saw that, too. We tried to find out that day what happened,but didn't get any official word as the team handed off the wheel to themanufacturer for analysis. Fortunately, we contacted Mavic to see whatthey had learned.LennardAnswer from Mavic:As

What say we give tire rolling resistance a rest this week?First, I wanted to tell you a little about the party we threw on August5 for the 25th anniversary of Zinn Cycles. Such a milestone does not comealong too often, and it was very interesting putting together the memorabiliacollected over a quarter of a century for the party. While it became brutally clear that the people who tell me and my wifethat we look the same as we did in college are stretching the truth, afar more interesting thing was to see how bikes have changed since 1982.I hope this doesn’t bore you (if so, skip to the

Aren’t aero’ covers on components a no-no?Dear Lennard,Floyd Landis's aerodynamic cranks have been described as both a "fairing" and a "cover." I thought aerodynamic covers on components isn't allowed.Steve Dear Steve,It isn’t allowed to have a cover on a component that is strictly for aerodynamics, but a cover can be made that serves an aerodynamic purpose while at the same time increasing the strength or rigidity of the component. That argument could be made with Floyd’s crank cover.Lennard How do they rig those aero-bar brakes?Dear Lennard,I've seen a brake lever on the CSC

Landis's drivetrain doesn't look standardDear Lennard,What's up with the crank used by Floyd Landis? And What about Landis's rear derailleur? It didn't look like a normal Record model.Chris Dear Chris,According to Francesco Zenere at Campagnolo, Landis's rear derailleur and Ergo Power levers are 2006 series Record models. And BMC made a special cover for Landis's Campy cranks for improved aerodynamic efficiency in time trials.Lennard What about Hincapie’s steerer in Paris-Roubaix?Dear Lennard,George Hincapie's bike had a blasted and black-anodized aluminum

I was struck when reading this question about what a strange world some of us cyclists live in, where bodily encounters with solid objects and even riding over fallen riders are commonplace. It got me thinking in the wee hours not only about bicycle geometry, which was the original gist of the question, but also about bruising, inflammation, Tyler Hamilton’s lower back and heart attacks! Now, either these are more closely connected than we may think, or maybe I should do more sleeping and less pondering in the wee hours, as connections between divergent thoughts that seem so profound long

Gord Fraser and Mike Sayers each got something special for this year’s Tour of Georgia (April 19-23), new bikes from their sponsor Cannondale. Now approaching mid-June, it’s hard to miss the growing number of big neon green sixes adorning the head tubes of many of Health Net-Maxxis riders’ bikes. In April, both racers were on pre-production prototypes, but now in less than a month, Cannondale is set to have the new rig ready for retail. The new bike, which mates aluminum and carbon utilizing the same process as Cannondale’s Six13, combines a complete carbon front end with a new CAAD 9

Fixing the unfixableDear Lennard,All Shimano chains now come with connection pin. Can a chain be safelyjoined with a regular pin? I have done that in the past by not pushingthe pin all the way through then pressing it back in when I had to replacea bent link or two. Is that safe with a 10-speed Shimano chain?Lloyd Dear Loyd,No, it is not safe with any 10-speed chain. The Shimano or Campagnoloconnector pin is double-length, with a front tip section designed to keepthe pin lined up straight while slowly opening up the two holes in anticipationof the part of the pin that will remain lodged in

Just back from the Giro d’Italia, I thought I’d give you a few photos from the Pontedera-Pontedera time trial and that you might not have seen elsewhere, including from the Piaggio (Vespa) museum in Pontedera, where the time trial (won by Jan Ullrich with Ivan Basso a close second) started and finished. David Millar came to the time trial to hang with his Saunier Duval teammates. He is very lean to the point that his pants also hang, ready to fall down at any time. My guess is he will be fit for the Tour prologue. It seemed to take me forever to ride from the 5K to go sign to the Monte

Steep, steep, steepDear Lennard,I recently read that Discovery director Johann Bruyneel is planningon putting a 34X29 on some of his riders' bikes for Stage 17 of the Giro.I don’t think Shimano makes either a compact Dura-Ace crank or a 29 cog.Any idea what they plan on using?James Dear James,I am in Italy now putting on a bikecamp with Connie Carpenter and Davis Phinney. We will be hookingup with the Giro starting at the Pontedera time trial on Thursday. I ameager to see the Stage 17 finish climb and the gearing teams use for it,too. According to Shimano USA and confirmed by Shimano

While XTR shifting systems made waves at last month?s Sea Otter Classic, Shimano left us in the dark concerning the details of the rest of the group. Still we don?t have the whole story, but Shimano has now offered a look at the new braking options the group will offer. The two most interesting features of the new system are the perpendicular or radial master cylinder on the brake lever and new mono-body design on the calipers. The new lever design frees up space on the bar and provides for a smoother modulating brake, while the single forged mono-body caliper lightens the system and

Mating Mavic, Campy and ShimanoDear Lennard, I've got some 2004 Mavic Cosmic Carbones with a Campy cassette and have recently bought a bike with Dura-Ace 10 transmission. What would I have to do to use the Cosmics on this bike?Andy Dear Andy,Those wheels would not shift worth beans using a Campy 10 cogset with a Shimano 10 transmission. You could buy and install a Shimano 10-speed cogset and a Mavic freehub body for Shimano (called "M10"), interchanging it with that "ED10" freehub body and Campy cogset. Alternatively, you may be able to locate some aftermarket cogs for a Campy freehub

The folks at Bontrager took an opportunity at last week’s Tour de Georgia to introduce additions to the brand’s high-end road racing product lineup. Major additions include an expansion of the Aeolus deep-dish aerodynamic wheel line as well as a new time trial disc wheel – all produced under a partnership with HED Cycling Products. Why aero?For the last few years riders have put a premium on weight and all but ignoring aerodynamics. Recently, even at the sports top level, aerodynamic advantage has only been considered when it comes to time trialing. But whether you look at a grand tour

Water SolutionDear Readers,It seems that whenever it is raining somewhere in the USA, I get questionsabout drain holes in the bottom bracket and rims. In the past, I have advisedpeople to drill their own if they are not present, but of course that isat great risk of voiding their warranties. However, here is a solutionthat might appeal to those whose bikes are filling up with water as wellas for those who do not want to void their warranties.LennardDear Lennard,I recently discovered it's not difficult to drill a hole down the centerof the set screw that holds the cable guide in place

Dear Readers, Well, I just got back from Sea Otter, and I’m sure you’ve read my review of the SRAM road group. There were lots of other cool things there, including pieces of the new XTR and lots of new mountain bike stuff from SRAM, Avid,Hayes, RockShox, Fox, Magura, Cat Eye, and many others. But one thing remained the same – my mailbox filling up with letters on the subject of wheel rotational weight and what difference it makes when climbing. The first time around, I published a letter saying it made almost no difference. The next time we revisited, I published letters saying it was a big deal.

Introduced at last year’s Interbike trade show, SRAM formally rolled out its new road group at Sea Otter this week, giving media and others the chance to actually ride what the once-little company is using to take on the giants of the component industry. The company is actually introducing two new road groups: the top-of-the-line Force group and the price-point Rival. Both share the same design on all components, with the Force group getting extra touches like carbon fiber lever blades, a magnesium lever body, and titanium gears and bolts. A pair of Force levers, for example, weighs in at

It may be almost Easter, but day two at the Sea Otter Classic at Laguna Seca Raceway felt something like Christmas — a stroll around the grounds on Friday was all about the boys and their toys. Subaru-Gary Fisher racer Jeremy Horgan-Kobelski was feeling a little bit under the weather, but nevertheless took time to explain the development process behind his new Race Day Pro Caliber full-suspension bike. Giant may have had the least-attainable bike in the pits (it was more prototype than production), but Adam Craig seemed happy with it. He was also able to shed a little light on the new XTR

The Sea Otter Classic’s season-opener status always leaves it vulnerable to inclement weather, and going into this year’s edition the Monterey Bay area has been awash in monsoon-style spring rains. But come opening day on Thursday, the ponderous clouds above the Laguna Seca race track gave way to clear skies and set a perfect stage for the 2006 season kickoff, for racers, spectators and exhibitors alike. Some of the loudest buzz in the pits concerns two of the industry’s component manufacturers, SRAM and Shimano. On Saturday, two SRAM-sponsored road teams will take the company’s new gear

Our Tech Report on frame stiffness in VeloNews issue 5, "Flexing Their Muscles," contained two errors, one of measurement and one of protocol. We incorrectly reported the weight of the Specialized S-Works Tarmac 56cm frame. The correct weight of this frame is 989 grams, or 2.180 pounds. The suitability of the 1999 Trek OCLV frame we used for comparison purposes was called into question at the conclusion of the test. Our intention in including the Trek was to use it as a well-accepted benchmark for carbon frame performance, prior to the recent push to develop ProTour frames that weigh less

Last week, we gave you the word regarding Shimano’s redesign of XTR; today, you get the pictures. And if you’re traveling to the Sea Otter Classic this week, you’ll be able to see the revamped components first-hand adorning the bikes ridden by Adam Craig, Walker Ferguson, Marie-Hélène Prémont, Bart Brentjens and Roel Paulissen. The new Dual Release triggers look extremely adjustable, and the WH-M975 wheelset is sure to be a competitor in the high-end-wheel game. The biggest surprise may be the new Dual Control disc lever, which appears to have a radial master cylinder like the one used by

Despite claims to the contrary, it’s pretty rare these days that a magazine or website will get an exclusive look at a new product. “Sneak previews,” and “spy photos,” tend to be just so much manipulation handed out to us hacks by some cagey character in the PR department, whose giving out the same “exclusive” shots to some other hack, with another magazine’s logo on his pile vest. So we were especially pleased to have an honest-to-gawd exclusive look at the latest creation from an old friend. VeloNews technical writer Lennard Zinn and wheel guru Steve Hed go back quite a few years and it

Dear readers, Back at Christmas, I threw in a letter from a reader claiming that rotating weight makes almost no difference on a wheel – that it takes negligible energy to bring it up to speed, and that the only thing that really matters when climbing is the overall weight of the bike, not how it’s distributed. Since then, I have gottena lot of mail about this, and a trip to France last week piqued my interest in this subject again. Perhaps some of you remember when I did a test in VeloNews seven years ago (in the 6/28/99 issue) of wheel inertia by building a rotational pendulumin my garage.

Shimano has taken a back seat to the competition’s barrage of buzz this winter. Eerily quiet until recently, declining to release any 2007 product information, Shimano began testing its new E-Dura-Ace group right as the ProTour season kicked into full swing. Now, less than two weeks away from the Sea Otter Classic, which traditionally opens the domestic mountain-bike season, Shimano has announced preliminary details of its redesigned ’07 XTR group. Though images of the complete group are unavailable (scroll down for photos of other new Shimano goodies), a trained eye can spot bits and pieces

Steve Hed was one of the first to build carbon fiber wheels – solid carbon discs – way back in the era of Francesco Moser’s hour records. At the time Hed was a partner in Grand Performance, a Minneapolis bike shop, but his interest in wheels and aerodynamics prompted him to sell his share and pursue work in carbon on a full time basis. For many years, Steve and his wife, Anne, ran Hed Wheels out of their house in White Bear Lake, Minnesota. Eventually, though, the business literally drove them out of house and home. Indeed, as the business grew, the Heds gave up and bought a new house,

Day two at the Taipei Cycle show and visitors continue to get intriguingpeeks at upcoming product that will likely appear in bike shops in nearfuture. Highlighting my trip through the hall today were a host of new tire options, some very economical pedals from CrankBrothers, FSA’scontinued progress toward creating a complete group and Aero guru, JohnCobb’s company, Blackwell Research, and its embrace of Taiwanese production. HutchinsonFrench tire manufacturer Hutchinson offered a little more insight toits tubeless road program, which should start making tires available thisfall. The line

As VeloNews first reported in its current print issue (see issue 4, March 13, "Shimano Tests Electric Dura-Ace in ProTour"), Shimano recently put battery-powered Dura-Ace drivetrains underneath nine ProTour riders. The wired systems feature LCD screens on the top of each STI hood, which otherwise look similar to 2006 cable-actuated Dura-Ace shifters. A battery pack is mounted on the downtube by the electric front derailleur. The system is still in early testing, and would not be available for sale until at least 2008, if at all. But Shimano, no stranger to electric shifting with its commuter

The 19th Taipei International Cycle Show opened March 8 in Taiwan, giving product managers four days to put the finishing touches on the 2007 model year, just two months and change into 2006. The show’s first day produced a number of new items; here are some of the highlights. SRAMSRAM has been doling out bits of information regarding its new road group of late, but that doesn’t mean the company has been neglecting the rest of its line. SRAM "leaked" some dirt on its X.9 mountain-bike derailleur and shifters last week, and while we can’t tell you much more now (expect details to be released

In its 19th year the Taipei International Cycle Show opened on Wednesday, offering product managers from around the globe a four-day opportunity to put the finishing touches on their 2007 product lines. Held in the Taipei World Trade Center, the show’s first day offered many of us a look at some interesting new items. Here are some of the highlights. SRAMThough the SRAM PR machine has been carefully doling out bits of information regarding its new road group, it seems SRAM has been using the new group’s release to divert attention from the rest of the line. The mountain components appear

After Ben Jacques-Mayne’s weeklong real-world test during last week’s Amgen Tour of California, SRAM’s new professional 10-speed road group comes one step closer to going public. While the group has been making waves since last fall’s EuroBike trade show in Friedrichshafen, Germany, SRAM did a good job of keeping its name — Force — under wraps. Now, with the name out there, the group once again steals the spotlight on its way to the retail market. The svelte shifters, newly designed carbon cranks and carbon-infused rear derailleur are the pro group’s highlights. The intentions to produce

Following SRAM’s European OEM camp in the hills above Malaga, Spain, photos of the new 2007 X.9 derailleur and shifters were leaked to European websites. In an effort to squelch rumors and hearsay, SRAM confirmed the redesign, releasing minimal information and photos of the components in question. SRAM’s official release follows: Here's some buzz that just leaked out. A well-positioned photographer snapped some sneak peeks of some of our new X.9 gear! Complete details will be released at Sea Otter. SRAM recently held a private test session in the remote hills of Malaga, Spain, where

Pressure washDear Lennard,Just wondering about a brief explanation on the “dos and don’ts” associatedwith bike cleaning and pressure washers. There seems to me to be two schoolsof thoughts around this and that pressure washers are a "no-no" that canruin components -specifically bearings, yet we see a lot of pro teams mechanicscleaning their teams bikes using stands and pressure washers? What areyour recommendations using pressure washers and some simple rules?DaveCanada (land of road salt and sand!)Dear Dave,My recommendation, in general, is to stay away from power washers.Of course, there

After straying from the usual question-and-answer format a couple of times recently, I have been encouraged to continue to mix things up a bit, so I’ll do it again today. This column does involve a technical question, one I have pondered considerably of late, so I thought I would share it with you, since I may not be the only one considering it. One of my favorite things to do in the summertime is to go on long road rides in the mountains. However, we all eventually get the message — sometimes subtly, sometimes not — that perhaps we are not as young as we think we are, especially when it

Those dang stripped threadsDear Lennard,What if anything can be done when the threads of a bottom bracket shellon an aluminum insert are stripped? I have not seen the bike firsthandbut I am trying to help someone out. They say that there is not enoughmaterial to cut new threads in. I assume that a tap has been runthrough already with no success. Is there any hope? I don't knowwhich side is stripped but if it is the non-drive side I can assume itis less critical. Is there a bottom bracket that will work better in thiscase?This is an old Look carbon time trial frame.JasonDear Jason,You

In keeping with my plan of varying things a little from the straight Q&A, I thought I’d use this week’s column to tell you about my recent visit to the USA Cycling (USAC) Bill Woodul Race Mechanics Clinic last month. Held at the Olympic Training Center (OTC) in Colorado Springs from January 12-15, the clinic offers a unique opportunity for shop mechanics wishing to be trained as race mechanics by some of the best in the country. It may also serve to open doors for participants to travel to international races and development camps in support of U.S. National Team riders. The setting under

Adjustable or disposable?Dear Lennard,Can you tell me if the bottom brackets on the two-piece style Shimano cranks have adjustable bearings, like those used in a hub or pedal or are they a non-adjustable sealed cartridge, like that used in the current Octalink bottom brackets? I don’t see separate bottom bracket bearings being sold for the new style cranks, so I’m guessing they are adjustable rather than disposable, but it’s just not clear. I need new mountain-bike cranks, but I chew through the Octalink bottom brackets pretty quickly, so a non-disposable bottom bracket would probably make

Save it or dump it?Dear Lennard,I have a 2004 model Trek 5200 , carbon frame road bike. The issue isthat rain water from Hurricane Rita affected lots of things in the garage,including the bike, since the roof was opened up by a falling tree. Thebike was really messed up, with its front wheel broken and the whole thingsitting in a foot of water.All of the components are ruined and when I removed the seatpost, waterpoured out of the frame, along with some small bits of white colored flakes.Is the frame salvageable with some type of treatment or is it, too, a lostcause?HalDear Hal,It may have

The limits of that braze-onDear Lennard,I just purchased a new compact Campy Centaur crank and front derailleur.I had a local bike shop install these on my steel frame bike and with thederailleur lowered all the way to the bottom of the braze-on we still havea gap of more than 8mm between the outer cage and the large chainring.It seems to shift okay but is there any spacer or part made that willlower this down to the 2mm spec called for by Campy or will it be finethe way it is? I tried the old derailleur and it installed with the suggested2mm of spacing. So I assume there is something in the

Is it the model year?Dear Lennard,I have a 1999 Cannondale CAAD 5 equipped with Campy Record 9-speed.It has never shifted to my liking. I just read on Campagnolo's web sitethat there is a difference between 1999/2000 Record shifters and post-20009-speed record shifters and derailleurs. This has me totally confused.They say there is a way to tell the difference but I am not sure how todo it.What I do know is that last year out of total frustration I purchaseda new 9-speed shifter, cable set, 9-speed chain and new Record rear cassette(12-23). It now shifts better but still not

Savings options? Dear Lennard, My question is regarding CO2 inflation cartridges. Is it okay to use CO2 cartridges that are labeled for use in BB guns and paint ball guns? I have been told that they contain a small amount of oil in them and because certain oils or lubricants can sometimes breakdown rubber that I should not use them. Is this true? These CO2 cartridges are sold at your local Wal-Mart or sporting goods store and are considerably cheaper. A box of 15 or 20 usually runs around 10 dollars as opposed to three or four dollars a cartridge at you local bike shop.

Making a Quantum leap?Dear Lennard,I have a circa 1996 Chorus 8-speed right index shifter (rear cogs). It is worn out and in a box. Do you know if it is possible to rebuild it as a ten-speed with the right parts?KhalilDear Khalil,No it is not. Eight-speed levers can only be upgraded to 9-speed, not to 10-speed. Also, the first year of 9-speed, with the current, more rounded shape to the knob atop the lever, could not be upgraded at all. After that, nine-speed levers could be upgraded to 10-speed.LennardTo click or not to clickDear Lennard, You recently received a letter regarding a freshly

A bunch of press releases, new products, and (gasp) a product alert have all piled up on my desktop over the past week. It’s time to purge. We first brought you the news a week ago, but we’ve since learned some more about the three-year deal between Health Net and Cannondale. The company will provide the team with Cannondale-branded clothing plus shoes and casual clothing from Diadora, a brand for which Cannondale owns North American distribution rights. "With the exception of Rudy helmets we’re head to toe," said Scott Struve, Cannondale’s product marketing manager. The riders have a

Screeeeeetch!Dear Lennard,I have a brand new Santa Cruz Blur equipped with Avid Juicy 7 discs. After a few rides in dry weather where the brakes performed flawlessly and silently, I rode the bike in the rain. I almost had to abandon braking altogether and just drag my feet to stop as the squealing sound was so loud it was shaking out my fillings. Since then, even in dry weather, the brakes continue to squeal on and off, and frankly I am afraid to use them in the wet again. The brakes are properly installed and bled. Did I not break them in long enough (three rides of easy road riding with

My fall is filled with cyclo-cross. Along with writing about exciting ’cross technology, I race on a single-speed and give up five weekends every fall to help a local promoter put on his ’cross series here in Boulder, Colorado. The finals, which doubled as the American Cycling Association state championships, were raced this past Saturday at Xilinx Software’s Longmont campus — complete with drum line. The men’s race was one of the most exciting local events I have been to in recent memory. I was a spectator because a lapse in concentration a week and a half ago, while testing the hardness

Dear readers,I am always amazed how a single reader letter can sometimes generate a flood of follow-up mail. Over the last couple of weeks I have received a good deal of e-mail about the potential problems people encounter when they soak chains in Simple Green for an extended period. Many of those notes focused on SRAM chains, and some writers suggested that it was the steel used in those chains that was the root of the problem.Now that I have learned a lot more about it, I doubt it. I believe that SRAM chains were mentioned most often simply because people who soak their chains for long

I got the galvanic corrosion and buzzin’ bottle boss bluesDear Lennard,I have a carbon frame road bike, and one of the water bottle bosseshas come loose. This makes for an irritating buzz, on any ride, and,I can't tighten the bolt sufficiently enough to stop the water bottle cagefrom bouncing a bit. Is there any type of epoxy, or other glue likesubstance that I can use to secure the boss?DaveHere’s an answer to your question from carbon guru Craig CalfeeMost carbon frames use aluminum Riv-nuts for water bottle bosses.The problem is that aluminum and carbon fiber don't get along well,

Ask your average die-hard cyclo-cross fanatic to comment on the burning social, political or economic issues of the day and you may not get much of a response. Ask, “Tubular or clincher?” and you’re bound to get an earful. Of course, much of what you hear is as likely to confuse as to enlighten. Old-school Euros will, without a doubt, defend their motto, “Tubulars or death!” North American racers with a mountain-bike background will thoughtfully explain that the tubular's advantages can be matched by superior rubber technology and the advanced tread patterns of today’s clinchers. No

With a host of common – and not-so-common – questions already answered in earlier Technical Q&A columns, I've been asked to touch on a few other topics now and then. In that vein, I will take this opportunity to tell you about the Gran Fondo Campagnolo, a very difficult mass-participation race I did for the third time this past June. The Italian Gran Fondo is a mass-participation event, but it is distinct from mass-participation rides here in the U.S. in that it is a race, and everyone wears a timing chip on his or her leg. The Triple Bypass in Colorado, for example (which I also did

Solving the solvent questionDear Lennard,Thanks for the recent notes regarding carbon fiber and solvents/lubrication.I wonder if you could recommend a safe way to remove old tubular cementfrom carbon rims. If you have already addressed the issue, can you pointme in the right direction?ScottDear Scott,This is one of those questions that warrants an answer straight fromthe horse's mouth. I sent off your question to a few carbon rim manufacturersand got these responses back.LennardAnswer from HedAcetone, a stiff plastic bristle brush, and a lot of time arewhat you use to get the cement off a

What are those pedals?It seems that lastweek’s column sparked a bit of interest in the pedals we hadmounted on the Zero G crankset. Well, those are M2 Racer’s ORB pedals andthe pair weighs in at just 99 grams. Fabricated from 6/4 titanium, theORBs feature 15 degrees of self-centering float. Their $228 price is wellwithin the ballpark for high-end titanium spindled pedals. The ORB is among a host of ultra-light M2 Racer products. Thecompany’s range includes a 43-gram saddle, a 69-gram seat post and a 6-grambottle cage. To highlight what a complete package of M2 Racer componentscan do, the

Zero Gravity is stepping up both its component development and its support for the sport in 2006, signing a three-year deal to co-sponsor the Jittery Joe’s road team and bringing a new crank project to market. Regarding last week’s sponsorship deal, Jeff Stewart, Zero G’s director of sales and marketing, said the boutique brake manufacturer has been "super happy with Jittery Joe’s." "We really have a great relationship with them. We put products on their bikes and get real world feedback," Stewart continued. As for the new Zero G cranks, which debuted at Interbike, Zero Gravity hopes to

Alberto Contador of Liberty Seguros has been hailed in Spain as the rider most likely to bring back the stage-racing glory days of Miguel Indurain. If such a thing is even possible, it may well be that Contador is the man to do it. And if not him, it may well be his younger teammate Luis Leon Sanchez. Able to climb as well as time trial, Contador is a big prospect for team director Manolo Saiz, who gave him his first pro contract with ONCE in 2003 and just signed him again for an extended contract. Contador, 22, and Sanchez, 21, made the trek from Spain to Boston in late September, with

Can I just have the new crank?Dear Lennard,I have an older Serotta Legend with 9 speed Dura-Ace and I wonderedif I can replace the crank set-up to the new stiffer 10 speed without compatibilityissues as I would like to leave the 9 speed rear end as is.

Center-pull cantilever brakes, once common on mountain bikes, are now completely gone from the racing circuit. However, as summer winds down, the leaves turn and cyclo-cross bikes come out of hiding, the center-pull cantilever can once again enjoy the spotlight. To understand what makes a good cyclo-cross brake, you first have to understand some of the intricacies of cantilever geometry, lever ratios and the whole idea of mechanical advantage. At the most basic level, a brake and its lever must be matched in terms of mechanical advantage. A prime example is a linear-pull brake (the

Insisting on an embargo until Thursday, the SRAM corporation has releasedadditional information on the shifting mechanism behind the company’s newroad components, first introducedat the Eurobike tradeshow in September.While show-goers and consumers have had a look at the group,bikes equipped with the new components were kept behind glass and thosewho who were allowed to play with the shifters were asked to sign a non-disclosure agreement. Few chose to argue the point with SRAM's six-foot-five-inch media rep' Michael Zellman.Now that the embargo is lifted SRAM is touting what calls its

Dear Lennard,Regarding your TechnicalQ&A with Lennard Zinn: Carbon tubes and lubes the consensusis unanimous that no grease be used on carbon seat posts, one thingwas not shared is how you remove grease from a seat tube if you want tochange to a carbon post from an aluminum post. If solvents shouldn’tbe used what can be used to safely remove grease that has already beenapplied? And on new frames should any prep be done to ensure thatthe frame is free of any contaminates before assembly.I want to share what I personally ran into with a new frame and carbonpost. Knowing that no grease was

In an industry increasingly dominated by mega-corporations, pumping outhi-tech, relatively affordable, but admittedly soulless bikes, you haveto wonder if there’s still a place for the small frame builder.How does a guy in a worn shop apron, often operating out of a garage,manage to compete against a sub-$1000 Chinese-made carbon frame?Quite nicely, thank you.“I do maybe 100 frames a year,” notes Ashland, Oregon's Mike DeSalvo.“That's not a lot for Specialized, maybe, but I sure stay busy.”DeSalvo Cycleswill never rival any of the biggies, but its owner and founder says that’snot the

As VeloNews.com has shown over the past week, Interbike offers a smorgasbordof cutting edge, high-end bikes and related goodies. It’s also filled withbizarre, who-would-possibly-buy-that type gizmos. Wading through the blinkingplastic safety vests to find the 100-gram rear derailleur is just partof the fun.

While the 2005 Interbike International Bicycle Expo has wrapped upanother busy week in Las Vegas, we're still sorting through our briefcases,hard drives and digital cameras for those things that left a big impressionon us. Here's a list of stories that our staff produced over a week inthe desert, but keep checking back, we'll be adding to the list for thenext few days.Interbike - Las Vegas '05Leaving Las VegasHighbrow saddles; Hi-Zoot technology; High-end carbonMore product; more photosOrbea:High-end bikes from the Basque countryInsidethe hall, a Day 1 photo galleryTanned,

Thecustom 11.9-pound bike on which Tyler Hamilton won the 2005 Mt. WashingtonHillclimb was on display in the Parlee booth (Parlee makes a Tyler HamiltonFoundation model, the proceeds from which go to Hamilton’s foundation).Parlee also showed a carbon bike with sculpted carbon lugs decorated withthe new superlight Alpha Q orange metallic GS-10 fork and matching Orangemetallic panels on the frame. Built up with Lightweight wheels, there washardly a steel part on it, but it was meant to evoke the steel frames ofold with sculpted lugs and painted frame panels. All Parlees can be

Produced in the heart of the Basque country, Orbea has a long history of producing carbon fiber bicycles. The company has invested heavily in monocoque molding technology and constantly refines and updates one of the broadest lines of carbon bikes in the business. The company is sure enough of its quality to offer a lifetime warranty on all of its frames, even the lightest of its carbon models.

The heavy and retroSurely the most elegant, no-holds-barred booth at the 2005 Interbike Trade Show in Las Vegas has to bethat of Brooks Saddles. The recreation of an English sitting room (exceptfor the fact that smoking is not allowed in the show) drove home the pointof how English this product remains since its purchase and re-vitalizationby an Italian saddle company, Selle Royal.The factory remains in Smethwick, on the outskirts of Birmingham, whichis where the gawdy red carpet with yellow flowers for the booth came from.All of thesaddles remain the same, made entirely out of thick leather

As Day 2 dawned on the most fun part of Interbike, namely riding cool bikes all over the great trails in Bootleg Canyon, the mechanical bull waited, its single horn barely attached but its pride and determination intact. Soon enough, in Yakima’s Bucking for IMBA promotion, one attendee after another came to be spun and tossed about by it while hanging onto a little stub of rope, all under the laughing gaze of people wearing pink foam Yakima-labeled cowboy hats. And sure enough, every would-be bull rider found themselves on his or her back soon enough, thrown off into an inflatable swimming

Fighting desert heat and a big afternoon windstorm, bike manufacturers did their darndest to keep Interbike tradeshow attendees happy for the second day of Outdoor Demo Tuesday, a task made easier by offering up a ton of new and interesting equipment. Giant Bicycles has big news for 2006, two new mountain bikes based on the company’s Maestro suspension technology. Our old colleague, Andrew Juskaitis, now Giant’s communications manager, said the two new bikes are the “bookends” of the Maestro series, offering the suspension design on both cross-country and downhill models. Billed as

Ibis is back and doing its thing... but this time in carbon.Tuesday marked the official return of both Ibis and its founder, ScotNicol, to the bike industry after a three-year absence. The brand thathad a devoted following in the 1990s and floundered on hard times sinceNicol sold the company in 2000.While Ibis fans have suffered the absence of a favorite, Nicol has spent the last few years most constructively: "retired and riding my bike." Not bad work if you can get it. Still Nicol has felt the itch and finally found his way back into bike biz' as a "partner" (read unpaid employee) in a

Interbike’s International Expo opened Tuesday, with more than 10,000 attendees swarming in among next season’s bikes on the red carpets of the Sands Convention Center in Las Vegas. After two dusty days of testing product at the Outdoor Demo in nearby Bootleg Canyon, the show moved indoors to get down to business. More than 10,000 buyers for about 3500 bike shops have registered to check out the 2006 wares that some 750 companies — representing more than 1000 brands— have on display. The business they do here determines what will be cropping up in your local shop in the coming months. That

The tradeshow season culminates with the start of the Interbike tradeshow in Las Vegas. Although the majority of the show takes place at the Sands Expo and Convention Center - in Sin City itself - the show actually starts a couple of days early, with bike demos in Bootleg Canyon roughly 20 miles outside the city limits. The area is renowned for exceptional mountain bike trails (a few have even earned IMBA’s renowned “Epic Rides” label to prove it). The Interbike folks have been coming to Bootleg canyon for the past few years, because the area offers demo’ riders the opportunity to try out

The 2005 Interbike show kicked off with a warm, cloudless day over the rocky, serpentine singletrack trails of Bootleg Canyon above Lake Mead. The venue has a short section of closed, divided paved road for road-bike testing and a vast area riddled with interesting singletrack for testing mountain bikes. The trail system offers so much mileage that, despite the large crowds at this well-attended Outdoor Demo, many of the nicest trails I had almost completely to myself all afternoon. Ah, the freedomA revelation for me was riding the Santa Cruz VP Free, the company’s all-out freeride bike.

Hey, be careful of those split tails!I just discovered a reason not to face your bike rearward on a roofrack, especially if you have a split-tail saddle. And another reason tofile the Nader hooks off of a road fork besides just the convenience ofgetting the wheel in and out! I was driving into my driveway with a bike on my roof as I have doneproblem-free for 15 years here. It’s a long gravel driveway lined withbig trees, and while leafy branches droop down, I keep the large branchescut back so no big ones cross the driveway less than 10 feet up. Both ofmy garages are full of bikes, so cars

The second day at the 63rd International Cycle Exhibition in the Nuova Fiera Milano proved substantially more hectic. In the past the show has been limited to industry insiders for the first two days; this year, only one day was afforded. When the doors opened this morning there was an air of urgency in everyone’s step. For the consumers, it was simple excitement, but for the vendors it was anticipation of a hard day’s work ahead. Highlights Saturday included visits to Shimano and Campagnolo. FSA had Ivan Basso on hand for a marathon autograph session promoting its compact cranks. Components

Milan’s 63rd International Cycle Exhibition kicked off Friday, celebrating Italy’s passion for the road bike and doing so in the massive and very new Nuova Fiera Milano. The new venue put all of the EICMA show’s attendees on the same level: We were all lost and most standing in slack-jawed amazement at the building designed by the famous Massimiliano Fuksass. Its 21,032 square meters of floor space increases the amount of room afforded the show by a whopping 25 percent. The convention center lies just outside of Milan’s city center. It can be reached by a convenient 25-minute subway ride.

The Eurobike trade show in Friedrichshafen first opened its doors in 1991. Back then it was a funky little thing that felt more like a gathering of the tribe than the prestigious international event it has become today. Friedrichshafen city’s old trade fair arrangement contributed to that feeling, consisting as it did of a mismatched hodgepodge of creaky buildings connected by a confusing warren of halls and passageways. The buildings were clumped around an irregular courtyard that the Eurobike show filled with test tracks, jumps, a BMX freestyle arena and the inevitable overflow of

Seat tubes and lube?Dear Lennard,I have been in the bicycle industry for many years and have consistently had conflicting advice about using grease in a frame's seat tube when using a carbon seatpost. With the many materials that frames are using now, are there some frames that should have grease in the seat tube when using a carbon seatpost, or is using grease in a seat tube with a carbon seatpost a big no-no? What do the majority of frame and carbon seatpost manufacturers have to say about this and why isn't it more clear? Also, if grease is a good idea, is there any particular

For our third day at the Eurobike show in beautiful Friedrichshafen, Germany, let’s take a quick tour of some new brands coming to the U.S., and new products from some established brands. Then, in our final report, we’ll take a look at the scene here, inside the halls and out in the courtyard, in an attempt to convey the unique flavor of this terrific show, now in its 14th year. AX LightnessAX Lightness components, much coveted by weight freaks, have been trickling into the U.S. for a couple of years. Production quantities are small, so they are sometimes hard to find. But if you have your

The Eurobike trade show in Friedrichshafen, Germany, is a wonderful place to gather information. It turns out it also is a good place to generate misinformation, as we inadvertently did yesterday. After seeing the Sram road group prototypes, we speculated about the shifting system, noticing that there was one shift lever behind the brake lever on each side, but no apparent way for the brake lever to swing or rotate to provide the other half of the shifting equation. Well, that’s because the one lever does it all. Today, we talked with two people who have used the system -- neither one of
