Overview
About this bike
The FX is a purebred race machine, created specifically for the rigors of the cyclocross racecourse. Its no-frills, the purpose-built design was developed for one thing: speed. Incredibly lightweight, stiff in all the right places, and unbelievably agile, the FX will elevate every racer’s performance. And that’s not an unsubstantiated claim by any means — the FX is a two-time winner of the cyclocross world championship in the ultra-competitive Elite Men’s division. So if it delivered the very best racer in the world to back-to-back rainbow jerseys, just think what it can do for you. The top step of the podium awaits. Go and take it. Whether you’re racing for a rainbow jersey or just aiming to beat your buddies at the weekend slugfest, you need a bike that will elevate the results of all of the blood, sweat, and tears you put into training. The FX is that bike, and once you take it into the trenches with you, no other bike will compare. - Felt Cyclocross UHC Advanced + TeXtreme carbon fiber frame and fork - Shimano GRX600 2x11 drivetrain - Shimano GRX400 hydraulic disc brakes - Devox Variable Road Cx2.1 tubeless compatible wheels
