A carbon fiber cyclocross bike has been the weapon of choice for cyclocross professionals from Belgium to Portland! Here's one that's actually affordable!

The frameset F5X checks plenty of boxes that would make a professional's wish list:


  • An ultralight UHC Advanced + TexTreme carbon fiber frame and fork that keeps total bike weight very low and torsional strength high

  • A tapered head tube and 12mm thru-axles reinforce the chassis further, producing razor-sharp handling on technical circuits

  • A BB386 bottom bracket anchors the crankset, ensuring instant pedaling response out of every corner

  • Internal cable routing keeps the F5X looking clean and extends the life of shifter cables and housing


All this combines to make the F5X an excellent performer on twisty and challenging courses. Even the underside of the top tube is flattened and shoulder-friendly, making run-ups just a little easier. Flat-mount disc brake installation all but eliminates caliper flexing, improving braking response and lever feedback.

Shimano's 11-speed RS505 dual-control levers operate a set of Shimano 105 derailleurs with precision, even during hard pedaling loads. RS505 levers offer adjustable lever reach for small hands without rubber spacers that might fall out on rough courses. The F5X's alloy FSA Gossamer Pro 46/36T crankset and 11-28T Shimano cassette provides classic cyclocross gearing. Tubeless-ready alloy CxR3 Disc wheels and 700x33c tubeless-ready Schwalbe X-One Allround MicroSkin tires bring low rotating weight and aggressive grip to the F5X; critical attributes for any competitive 'cross machine. Shimano RS505 hydraulic disc brakes ensure confident stopping power in all conditions, rain or shine (or mud)!

Prologo's Nago Evo x10 saddle sits atop an alloy Felt CxR2 seatpost, while an alloy CXR SuperLite stem and alloy CXR SuperLite road handlebars complete the F5X.
