Product Information

Specialized S-Works Crux Men's Cyclocross Frameset

The S-Works Crux Frameset is the start to building the "ultimate" cyclocross bike. Built with Fact 11r carbon fibre in a brand new paint job, the S-Works takes cyclocross to new depths. 400g lighter than its predecessor thanks to re-designed tube shapes and bottom bracket shape, the Crux is as lightweight and it's stiff and responsive on technical descents and tight turning courses. Flat mount disc brakes, through a thru-axle design, ensure reliable braking at every opportunity, no matter how tough the weather conditions get and how difficult the surface becomes. Finally, 8mm of clearance even on 33mm tyres guarantee plenty of space to add mudguards and racks for winter training or commuting as well as removing any risk of your wheels becoming clogged up in muddy conditions.

Jamie Bedwell Says

In 2016 I bought the Crux frameset and kitted it out with a Shimano 105 hydraulic disc groupset and the Mavic Aksium wheelset. Since then it has become my go-to for every session, on ride, off-road or on the gravel paths, the Crux is the ultimate training bike.10/10
