Pro bike: Marianne Vos
By Ben Delaney in Boulder, Colorado | Tuesday, August 14, 2012 1.40am
Holland's Marianne Vos is arguably the world's most successful multi-discipline racer active today. Having won world titles on the road, on the track and in cyclocross, not to mention her victories in prestigious road events like the Giro d'Italia Femminile, Vos added another impressive line to her palmarès in London with a win in the Olympic road race.
Vos won the Olympic race in the rain aboard a Giant TCR Advanced SL.
Olympic cycling competition rules dictate that branding be kept to a minimum - one logo per side of each wheel, one company name on each side of the bicycle - but after the Olympics, of course, those rules are off. Rabobank, the trade team for which Vos rides the rest of the year, quickly capitalized on their rider's success and bling'ed up her bike with gold graphic on the frame and wheels.
Vos' Olympic bike features a fairly straightforward, if expensive, set-up. Electronic Shimano Dura-Ace Di2 shifters are mounted on a carbon Pro Vibe handlebar (40cm), and Shimano C35 tubulars are wrapped with 23mm Continental Competition tires.
Vos uses Rotor Q-rings, however, with a 52/39 ring configuration.
Giant's TCR Advanced SL frame is built using carbon fiber made in Giant's own carbon facility. The top tube and seat tube are woven together, then remolded under heat and high pressure. The frame also gets a carbon nanotube polymer added into the resin, which Giant says greatly improves impact resistance.
The OverDrive 2 fork features a tapered steerer tube that runs from a 1.25-inch top bearing to a 1.5-inch lower bearing.
Her bike shown here is the TCR Advanced SL she raced in London, after Rabobank gave it the golden once-over.
