Pro Bike: Marianne Vos’ Giant TCX Advanced SL

Marianne Vos proved she was a force to be reckoned with one again, securing her sixth Cyclocross World Championship in Louisville, Kentucky. The 25-year-old Dutch powerhouse road effortlessly away from her competition aboard her Giant TCX Advanced SL.

The TCX Advanced SL has short seatstays that join the seat tube about a hand’s width below the top tube and is one of the few ‘cross bikes still sporting a seatmast.

The Rabo Women racer rides a size small frame. It has a 535mm effective top tube and a relaxed head angle of 71°. Vos has a very aggressive position on her bike - notable for a 5ft 6in (1.68m) female - with a staggering 10cm of saddle to handlebar drop. The fit does appear to be optimized for riding on the hoods; Vos also runs top-mounted brake levers.

Like many other Shimano-sponsored ‘cross racers Vos uses Shimano’s 35mm deep C35 carbon tubular wheels. She chose to run Dugast Typhoon tires for the frozen-yet-slowly-thawing world championship course.
