Well, the manuscript of the third edition of Zinn and the Art of Road Bike Maintenance is due today, and I’ve been burning the midnight and daybreak oil for some time now, especially the last week, to get it done. Still not certain I’ll make it. But somehow, despite not riding or answering the phone these days, I got sucked into answering this question in some serious detail while writing Chapter 8 on cranksets. Back to the book now. Lennard

Web site: www.hutchinsontires.com[nid:85576][nid:85577] Have you been looking to run tubeless tires on your road bike? If not, here's a few reasons why you should: no pinch flats; ability to run lower pressure for better traction and a smoother ride; less weight than traditional tube-dependent clinchers; less expensive than tubulars. Now Hutchinson offers a variety of 127 tpi tubeless road tires. The Atom is a single compound, slick-type road tire that offers low weight, safety, and dry weather race performance.
Price: $95 to $125[nid:85546][nid:85548] Web site: www.sanmarcovintage.com In the world of cycling, fashion is determined by small details that are typically overlooked by the "noobs" and those not involved in the sport. One of the more subtle, yet convincing ways to step up your cycling fashion is with a classy saddle.
Matching your tire to a course’s conditions is a key to achieving the best possible result. There are currently three major tubular tire manufacturers that design, manufacture and produce complete tire lines: Challenge, Dugast and Tufo. Each manufacturer’s line is made up of three models — file tread, all-condition and mud — in a multitude of sizes.
Katie Compton, four-time national champion and worlds silver medalist, does not have a component sponsor. Compton and her mechanic husband Mark Legg, are not entirely pleased about this state of affairs, but the pair does enjoy the freedom to choose the parts they prefer.
Dear Lennard,
I'm a 39-year-old, 175 lb., 150-200 miles-per-week recreational rider who frequently rides long charity rides and occasionally races. I recently switched to Specialized Armadillo Elite tires to avoid a rash of flats I'd been having, and they've worked wonders (no flats at all since the switch.) I had most recently been riding Schwalbe Stelvios, and Michelin Lithions prior to them.

The price of 11s
Dear Lennard,
I have been riding Campagnolo components for years and years. The new 11s stuff looks great, but the new 11s cranks are not inexpensive.
I cannot understand why given a 5.5 to 5.9 mm difference in changes the 10s crank would not work fine. Do you have any experience with the 11s parts used with a 10s crank. I happen to have a carbon 10 crank, first generation, Record.
Jeff
Dear Jeff,
I think you’ll find that your Record crank will work just fine with the 11-speed group.

To a cycling enthusiast, the fall Garmin-Chipotle team camp may look like Christmas for the 28 riders on the squad, but to them it’s another day at the office. Whether they’re thumbing through Fi’zi:k’s ‘Blackbook,’ the brand’s 2009 saddle catalog, trying to decide which saddle to choose or test, or they’re submitting sizes for 2XU compression gear, or sitting through a lecture on wheel selection by sponsor Zipp — it’s all work.

One of the neatest features of Garmin Edge GPS bike computers is the "Virtual Partner," which lets you race against a previous trip over the same course, with your relative positions marked by little cartoon riders on the screen. It's a geeky fun distraction, even if its name is a little creepy. But what if you are a professional racer, looking for tools, not amusement? How could you use that feature?

Kona Bicycle has a new line of gloves with models for mountain biker, freeriders, roadies and kids. The men’s Chevron glove ($25) is intended for cross-country. It features a Chamude palm for increased durability, silicone grip finger tips for better braking control and a terry snot wipe thumb. The women’s XC glove offers an air-mesh palm with Chamude overlays for added durability and circulation, 4mm gel palm pad and gripped finger tips.
Fairwheel Bikes makes colored hoods for recent Campagnolo and Shimano's Dura-Ace, Ultegra and 105 shift/brake levers. Hoods for SRAM levers will be available later this year. The company says the hoods are exact replacements and are available in six colors. Suggested retail is $25.
Joy Industrial's Novatec hubs may become a popular item among wheelbuilders, because they allow relatively easy swaps between four different front hub/fork drop out standards. Riders with multiple wheels and forks in their garages also might find these hubs convenient. The 4in1 front hubs can interchange — without tools — to fit standard quick releases, or 9mm, 15mm or 20mm thru axles.
Kenda showed a 650B (also known as 27.5-inch) John Tomac Nevegal at the Taipei Cycle show last month. The company showed the new tire diameter in a 2.35-inch width and said a 2.1-inch width will be available soon. The diameter splits the difference between traditional 26-inch mountain bike sizes and the fast growing 29-inch hoops, said Kenda's Jim Wannamaker. "From a design standpoint, this new wheel size makes sense. It allows a bigger wheel to be
Fox has a slew of improvements to its product line for 2009, but two stand apart: A remote lockout for the F80, 100, 120 RL forks and a new thru-axle standard called 15QR, which is an option for all of its 32mm stanchion forks.
The Everti 29R is a hardtail titanium 29er frame, designed and built in British Columbia. Kurt Knock of Everti said the frame has been in development for about a year. It features 3/2.5 titanium, with double-butted top and seat tubes, and straight-gauge elsewhere. The downtube is oversized and ovalized at the head tube, and the head tube is longer than most 29ers to distribute the extra stress created by a longer fork, Knock said. The frame also features a mini-gusset at the head tube/downtube juncture and full length cable housing.
It might surprise you to find out just what it takes to build a one-off bike. Travis Brown can sure tell you. The Trek test rider and product developer lost one after last year’s early fall single-speed world championships. Trek built Brown a custom polished one of a kind 69er single speed for the event in September. After a pre-ride, derby and race, Brown UPS’d his bike back to the U.S. and the men in brown promptly lost it.
As the Sea Otter Classic swings into full force in addition to people pouring in for the festival and the races kicking into gear, there proved to be no shortage of new stuff to see. The weather is holding, which is always a question in April on the Monterey Peninsula, so without further ado let us dive right into it.
Trek development rider Travis Brown was at the Trek team truck at the Sea Otter Classic sporting a never-before-seen set of white and red Bontrager mountain bike shoes. The shoes have a large RXL logo on the middle strap that threw many for a loop. "People keep asking me if they’re from Polo Sport," said Brown. Ralph Lauren was a common sight at Sea Otter in previous years with his now dissolved RLX Polo Sport mountain bike team.
With the world’s best racers descending upon Houffalize, Belgium, for the World Cup opener, the Sea Otter Classic needed to supplement this year’s world class downhill races with something extra to keep the event growing. For the Sea Otter, now in its 18th year, the answer was to bolster the festival and promote the tradeshow aspect of the event. It’s a trend that has been building for the last few years as more and more manufacturers are using the Sea Otter as a launching point for new product coming down the pike.
A Nevada court has delayed ruling on a request by the owners of Lew Racing to bar competitor Edge Composites from displaying or selling products that Lew alleges were made using a “secret process” it developed.
Dear Lennard,
I've just read your article article about the SRAM ceramic bottom bracket and its maintenance. We at CeramicSpeed have been working with ceramic bearings for the past 11 years, introducing systems for bicycle applications eight years ago.
In this four-part video tutorial, VeloNews Tech Editor Matt Pacocha walks us through the procedures involved in properly gluing tubular tires.
You’re saying there’s a chance? Well, when there was, Mario was ready to turn some heads. Carbon Sports, the manufacturer of Lightweight wheels, was commissioned to build Rock Racing's Mario Cipollini something special for Milan-San Remo, but when Cipo and Rock Racing didn’t get an invite, then parted ways, this special wheelset became obsolete — to Cipollini anyway.

The Beijing Olympic mountain bike course is punctuated by short, steep, smooth climbs that favor a powerful rider like Giant’s Adam Craig. The descents on the Chinese course, too, are smooth. It’s the sort of terrain that doesn’t offer advantage to Craig’s Anthem Advanced full suspension bike; rather it calls for a light, stiff frame able to transfer maximum power on smooth trails. Giant just delivered on Craig’s special request for an Olympic hardtail.
Rapha’s pricy, chic line of retro-modern cycling clothing is built from a mix of technical and natural fibers including Merino wool, wool hybrids and synthetic fabrics by Swiss Schoeller.

Are ceramics that delicate?
Dear Lennard,
In your article on ceramic bearings in the recent VeloNews Buyers Guide I got the impression that these things were not only smooth but durable as well. As a result, I ordered a ceramic SRAM bottom bracket with the Red crankset on my new bike.
To say the least, I was surprised when I read the SRAM maintenance instructions that came with it and saw the recommendation that one should disassemble and lube the bearings after every 100 hours of use and immediately after riding in the rain or wet.
Revising its original plan to reserve its Record Red Ergopower shifters for professionals, Campagnolo announced Thursday that it will offer a limited run of the special heavy-action shifters to the public. The pro Ergo levers incorporate stronger springs for a more tactile action. Campagnolo says that the change was made to appease elite riders who use the crisper action to “feel the shifts at the hardest moments of the race.”
Shimano’s electric Dura-Ace is becoming more and more common in the ProTour peloton. Gerolsteiner rider Stefan Schumacher scored a podium placing on it at last year’s world championships. For three years now an electric prototype group has been raced in the spring classics and semi-classics. Last year it was also in cycling’s biggest show, the Tour de France.
Dear Lennard, Question for you re: forks for long head tubes. I'm 6'4" and have a Seven Axiom with a roughly 30cm head tube and a Seven rebadged Reynolds carbon fork on it. It is a bit flexy when braking while cornering and I'd like to improve that. What options are out there and how do they rate vs. each other? I know Alpha Q makes one with a steerer long enough (as seen on your bike) as does Storck, but want to understand if they are better than the Reynolds vis a vis flex/rigidity. Ted Dear Ted,
NEWS FLASH: I put Centaur Ergopower levers on my SRAM Red-equipped bike and have been riding it happily ever since with nary a hiccup in the shifting. I have a SRAM 10-speed chain, SRAM Red chainrings, SRAM Red front derailleur, SRAM Red rear derailleur, and SRAM Red 10-speed cogset mated with the Centaur 10-speed Ergopower levers. This means that Campagnolo and SRAM 10-speed road shifters, including their bar-end models, pull almost exactly the same amount of cable with each click.
Titus Cycles, Inc., an Arizona high-end bicycle makers, has been purchased by Great Arizona Investments, a group that has holdings in a variety of industries. The new owners have created a business called GAI Cycles to operate Titus and any other cycling projects they enter. Titus, based in Tempe, had been owned by Vyatek Sports. The company was founded in 1991 and makes road and mountain bikes in stock and custom sizes, from aluminum, carbon and titanium. Titus CEO Pat Hus said the company has grown significantly in the last three years.
After racing the final 22 kilometers alone, off the front, Francaise des Jeux rider Philippe Gilbert crossed the finish of Omloop Het Volk last week in victory. It was the second Het Volk win for the Belgian; his first came in 2006. The 2008 win was special to two of his sponsors and was a milestone for road technology, because Gilbert crossed the line on a tubeless wheel and tire.
Dear Lennard,
In a recent article you make mention of the fact that you do not use adhesive tapes, like that produced by Tufo, on tubular wheels, preferring instead to use the old system of building up with glue.
A German rider with a penchant for lightweight rides has put together a 3195-gram (7.04-pound) road bike that he says is sturdy enough for him to ride up to 1000 kilometers a week. Günter Mai from Lampertheim has modified virtually every part on the bike, including the set of custom Lew Racing Pro VT-1 wheels. Off the shelf VT-1 wheels weigh 850 grams a pair and are made for use by riders up to 185 pounds. They sell for about $6000, while custom wheels like Mai's cost $15,000.
A recurring pain
Dear Lennard,
I'm writing because I just read the shoe review in the VeloNews Buyer's Guide, and you mention in there that you use a custom orthotic.
I was happy to see that the Shimano SH R300's I just purchased got high marks, but I am still having issues with my right foot even with the new shoes. I got the new shoes because I was having the problem with my four-year-old Northwave Evolutions.
Last month, Travis Ott, Gary Fisher’s brand manager and Subaru-Gary Fisher team director, personally delivered a new cross-country racing version of the brand’s HiFi full suspension frame to team riders Jeremy Horgan-Kobelski and Heather Irmiger. During our meeting in their hometown of Boulder, Colorado, at one of the coffee shops preferred by the pros, Horgan-Kobelski and Irmiger, who are married, gave the bikes a good look over while Ott ran through the basics of the new design.
Craig Calfee hopes to prove that one person with one idea can make a difference in some of the poorest corners of the planet. The maker of some of the most exclusive and sought after carbon-fiber bikes on the market, Calfee plans to use his knowledge to teach Africans how to build themselves bamboo cargo bikes.
The original Blur LT was introduced three years ago and the all-mountain rig has become the brand’s bestseller. But the company is releasing a remodeled design intended to keep it at the top of its heap. The most visible new feature is the use of a carbon fiber upper VPP link. Less visible but more important is a careful re-tooling of the linkage’s shock rate. Santa Cruz engineers mellowed the rate out to offer a supple beginning stroke and and a linear feel all the way through to bottom out.
This past weekend’s trip to the Wisconsin north woods for the 35th American Birkebeiner, which for many cyclists is a festival of extreme winter cross-training, got me thinking about traditions. Being able to count on the recurrence of a tradition is comforting. Yet underneath, traditions can be fragile, no matter how long they have survived.
From the perspective of executives at Pearl Izumi, the company’s sale to Shimano American Corp., announced Tuesday, was a relief. Other potential buyers — mostly venture capitalists — were eyeing the Colorado-based clothing company like a house flipper eyes a fixer-upper: something to throw a new coat of paint on, then re-sell for a huge profit. Shimano officials, however, look at Pearl like a young family sees a home, with plans to move in for the long haul. At least that’s how Pearl officials see it.
One more gear?
Dear Lennard,
We have a 27-mile climb just outside of town that I ride up occasionally. My problem is that I tend to spin out on my way back down and find it difficult to keep up with some of my riding partners. A friend of mine told me that I could swap my 10-speed Shimano cassette (12-25) for a SRAM (11-26), which would give me both a better climbing and descending gear. Although I understand 45MPH is plenty fast, is the swap compatible?
Brian
Dear Brian,
Gerolsteiner rider Fabian Wegmann is the one rider in the Amgen Tour of California on the latest prototype version of the Shimano Dura-Ace group. VeloNews spotted it before the start of stage 1 in Sausalito, and got the walkthrough with Gerolsteiner's Michael Rich, a friend and training partner of Wegmann, and the team's directeur sportif in California.
Dear Lennard,
I'm confused about the BB30 design. How do they increase the spindle diameter from 24mm to 30mm and put the same sized bearings inside the BB shell? Is a larger diameter BB shell the design change the article mentions?
James
Dear James,
Yes, the bottom bracket shell is larger. Here are specs: www.bb30standard.com.

The North American Handmade Bicycle Show was quite a draw this year for boutique frame builders and their fans — including Lance Armstrong, Brian Lopes and Robin Williams.
A half hour before the doors opened for day two of the North American Handmade Bicycle Show in Portland, the crowds piled into the Oregon Convention Center’s lobby to wait. Each had paid $18 for a day’s worth of access to more than 150 of North America’s finest small- and medium-sized frame builders, as well as a few big-time component manufacturers.
