Pro bike: Marianne Vos’ Giant TCX Advanced SL

The six-time world cyclocross champ’s machine

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


The TCX Advanced SL has short seat stays 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 Rabobank racer rides a size small frame. It has a 535mm effective top tube a relaxed head angle of 71°. Vos has a very aggressive position on her bike—notable for a 5-foot-6 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.

Vos runs a 10-speed Shimano Dura-Ace Di2 group, which has proven itself reliable throughout frequent muddy races and subsequent power washings. Other notable components include ovalized Rotor chain rings. Vos is a firm believer in their effectiveness in eeking out every last possible watt from her pedal stroke; she uses them for ‘cross as well as on the road.

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.
