The battery pack tucks under the stem.

Old Shimano Flight Deck buttons were wired into a Di2 group and mounted snug against the grips.

TT bikes weren’t the only ones with Di2 at the show. Fair Wheel Bikes built up a mountain bike with a modified electric road group.

Besides a sweet stem paint job, Martin also runs Di2.

Tony Martin placed third at the world time trial championships this week. His other TT bike was at Interbike.

No brake back here. It’s down under the bottom bracket.

Kestrel’s 4000LTD will run you a cool $10,829.

2009 Interbike: With Di2, you can shift at the end of the bar extensions and at the brake levers.

Adding electric shifting to a bike adds options for shifting positions. It also adds a substantial cost.

Orbea’s Ordu is one of an increasing number of time trial bikes running Shimano’s electric Di2 group.

Cannondale engineers shoot for the moon with concept bikes, such as this commuter option, then work down to something viable for the marketplace.

Cannondale’s Flash weighs 16.6 pounds. The frame features continuous carbon fiber strands that run the length of the design. For example, the top tube fibers run from the head tube, around the seat tube, down through the chain stays.

Dubbed a “Bead Seat Clincher,” the Reynolds system features a two-depth inner. The clincher sits in the deeper valley when mounted. When the tube is inflated, the clincher’s bead is pushed out into the top valley. Since the tire’s bead circumference is substantially smaller than the rim’s outer, the tire sits snugly.

“We didn’t pick the depth, the depth picked us,” said Paul Lew. The original mold had to be modified, as the inner trailing edge was sharp to the touch. The rim will be built up early in 2010 with a RZR hub and spokes.

The Reynolds 92.2 rim is remarkable in two ways: it’s a carbon clincher without a bead hook, and the rim is substantially wider than a standard tire.

With its RZR wheelset, Reynolds has plenty of buzz in its booth at Interbike. But the company’s forthcoming 92.2 rim is equally as remarkable, as the carbon model redefines how a clincher tire mounts to a rim. Paul Lew works as a consultant for Reynolds. In addition to his cycling experience, Lew has built unmanned flying vehicles. His inspiration for the 92.2 came from aerospace designs. “No aircraft wheel uses a hook,” Lew said, referring to the inner lip of a clincher rim that typically holds a clincher tire in place.

Out of the Arizona desert comes the Titus crew and their dually carbon 26ers, alu and ti options and a Rockstar 29er.

The Tour of Ireland will return to a five-day schedule in 2010, organizers announced Friday. The dates for the 2010 edition were confirmed at the UCI Congress in Mendrisio, Switzerland, this week. The dates for the five-day tour are 18th to 22nd August 2010.

Unlike a grand tour or a classic, or any other major annual bike race, the world road championships is the sport’s only prestigious event that has the whole world looking on — and the organizers have only one chance to do it right. That’s because the Union Cycliste International selects a different country (and city) every year to be the host.

Markus Storck has long wanted 2005 Ford Ironman Hawaii Triathlon World Champion Faris Al-Sultan to race on his bikes, and when the sale of Cannondale opened up the opportunity to put his fellow German on a Storck, he quickly got to work. Even while working on prototyping a new electric bike and constructing a new building, Storck came up with the Aero 2. “I got no sleep for four months,” says Storck, “and now I need a vacation.”

Garmin-Slipstream’s Bradley Wiggins has disputed reports that he is looking for ways to get out of the final year of his contract with the American-sponsored team. Responding to interpretations of an earlier BBC report that implied that staying with Garmin-Slipstream is unlikely to boost his hopes of finishing on the Tour de France podium next year, Wiggins said he has no plans to leave his team. “I have a lot of love for Garmin and these stories are not my thoughts on Garmin,” Wiggins said in an email to VeloNews.

We got a first look at a new 2010 DT Swiss wheel line in Germany, at the Eurobike show. Like so many things over there, we ran out of time to have a good look and get the story out. Fortunately, DT Swiss is well supported here in the States with a U.S. office, and they put on a great show here at Interbike as well. DT Swiss’s “Tricon” line includes one road wheelset and one mountain bike wheelset. Tricon technology refers to a complete system of hub, spokes and rim, which are not sold as separate components, only built into a complete wheel.

Rabobank sprinter Theo Bos has signed a two-year contract with the Cervélo TestTeam. The 26-year-old Dutchman and the team made the announcement at the world road championships in Mendrisio, Switzerland. Bos originally made his mark as a track racer, earning five world titles and a silver medal in the matched sprint at the 2004 Olympics in Athens. Bos made the move to road racing in 2009, winning several events including the Ronde van Noord-Holland and the Omloop der Kempen.

A court in St. Petersburg, Russia, has sentenced the murderer of Olympic gold medalist Dmitry Nelyubin to 18 years in prison and fined him 45,000 Euros. The court had earlier found Alim Azagoyez guilty of stabbing Nelyubin in the early hours of January 1, 2005. Nelyubin was a member of the gold-medal-winning Soviet team pursuit squad at the 1988 Olympics in Seoul Olympics.

Running unopposed, UCI president Pat McQuaid was reelected to another four-year term Friday following a UCI congress held in conjunction with the world road race championships. The 60-year-old Irishman was the only candidate for the post, which he took over from Dutchman Hein Verbruggen in 2005. A former professional racer in the 1970s, McQuaid has also worked as a cycling coach, race organizer and president of Ireland's national federation. During his tenure McQuaid has worked hard to help globalize the sport, especially in Asia, the Americas and Oceania.

Australian Cadel Evans said he has virtually no chance of winning cycling's coveted rainbow jersey on home soil next year when the world road race championships are held in Geelong. Evans, who finished runner-up in the Tour de France in 2007 and 2008, is among a handful of contenders looking to end Spain and Italy's domination of the competition's road race here on Sunday. And he feels the profile of the 13.8km circuit that the peloton will race 19 times for a total distance of 262.2km suits his climbing talents better than the 2010 course.

Heading into its sixth season, the U.S. Gran Prix of Cyclocross kicks off Saturday in Madison, Wisconsin, with The Planet Bike Cup, a new event to the series. The timing of the addition makes it possible for riders such as Katie Compton and Jonathan Page, both sponsored by Planet Bike, to participate in the USGP — an opportunity both have had to forgo in the past due to their World Cup racing schedules.

Vuelta a España stage-winner Ryder Hesjedal has agreed to stay with Garmin-Slipstream through the 2011 season. “I’ve signed to stay with the team for two more years. The team has been pleased with me and I am very happy with the team,” Hesjedal told VeloNews. “It was pretty simple. We were always on the same page. We were in agreement early in the year to work out an agreement.”

Eric Barlevav won the final race of the USA Crits series Thursday night in Las Vegas, with his Mountain Khakis teammate Mark Hekman winning the field sprint behind to claim the series title. To put the cherry on top, Mountain Khakis won the team overall prize for the 2009 USA Crits. “It’s huge to win here,” said Barlevav. “USA Crits was definitely a big goal for our team. We tried to win all the races, and we tried to win the overall, so this is great for us.”

Kona wanted what all full-suspension bike manufacturers want in a trailbike, a platform that does everything well. But the solution isn't always so simple.

Diadora’s ProTrail 2.0 is the off-road counterpart to the ProRacer 2.0. A unique feature is the included Multi-Pad (with red bumpers), which secures the contact for pedals like the crankbrothers Egg Beater.

The middle Velcro strap uses a cam lock to secure the fit.

The ProRacer 2.0’s upper strap is removable.
