Pro bike: Zdenek Stybar’s Specialized S-Works CruX

A look at the 2014 Cyclocross World Champion’s race rig

Although a skilled cyclocross racer who already had two world titles to his name, Omega Pharma-QuickStep rider Zdenek Stybar came into this year’s World Championships as an unlikely contender. He’d participated in only one ’cross race this season prior to pinning on a number for worlds, and his start position was three rows behind race favorites Sven Nys and Lars van der Haar.


But it appears the many miles he’s been logging in Mallorca, Spain, in preparation for the Spring Classics is beginning to pay off. The 28-year-old Czech racer powered from his position near the back of the pack to battle Nys for victory aboard his Specialized S-Works CruX.

Not the latest for the greatest

Despite his victory on the rough and rutted Hoogerheide course, cyclocross is not Stybar’s focus this year, a fact made evident by his equipment. While most of Stybar’s competitors ride bikes outfitted with the latest 11-speed groups, Stybar had older 10-speed SRAM Red kits mounted to his S-Works CruX framesets.

In fact, Stybar’s carbon S-Works CruX framesets are kitted out with nearly same components as when we last profiled his pink alloy CruX in 2012.

Introduced in 2012, the s-worx crux was designed with stybar’s input to be a ‘tarmac for the dirt’:

In addition to the 10-speed SRAM Red group, Stybar runs the very capable Avid Shorty Ultimate cantilever brakes set in the narrow position for increased stopping power. His cockpit consists of a Zipp Service Course handlebar and stem with a carbon Zipp Service Course SL Speed carbon seatpost with a Specialized S-Works Toupe saddle. Wheels are also provided by Zipp in the form of the 404 Firecrests. On race day Stybar opted to run Dugast Rhino treads front and rear.
