Considered by many to be the best in the bike the business, Felt’s TeXtreme carbon fiber makes the F3x cyclocross bike exceptionally stiff, strong and light.

Felt completely revamped their new 2016 cyclocross and gravel bike line and fans of dirt roads, liege waffles, frites and cowbells are rejoicing. Their new disc-specific carbon FX ‘cross platform is lighter, stiffer and has better tire clearance for fat tires and muddy races. We think the F3x cyclocross / gravel bike is the sweet spot in the new CX lineup. It features Felt’s UHC Advanced + TeXtreme carbon fiber, Shimano hydraulic disc brakes , an 11-speed Shimano Ultegra drivetrain, and DT Swiss disc-specific thru-axle wheels rolling on Schwalbe X-One rubber. Like the Bionic Man, Felt rebuilt their ‘cross line faster, lighter and stronger and it’s one of the most exciting and competitive out-of-the-box cyclocross bikes on the market. If the TeXtreme carbon fiber alone isn’t sexy enough, the new Belgian-inspired graphics push it right over the top. It even comes with a cow bell.

Frame: The F3x frame is constructed of from Felt’s UHC Advanced + TeXtreme carbon fiber MMC with InsideOut construction, resulting in an extremely light, stiff and polished frame. The frame design has been refined for increased stiffness at the headtube and bottom bracket, as well as added tire clearance. However, Felt claims that even though the new frame is generally stiffer, overall compliance and comfort have not be compromised. The new FX frame design features internal routing brakes and shifter cables, including Di2-compatibility. They even included an extra port for a dropper seatpost, for riders who want to get extra rad going over the barriers.
Disc Brakes: Disc brakes have taken over in cyclocross. They offer superior braking power and control regardless of conditions and they’re now light enough that there’s no significant weight penalty. The Felt F3x frame is disc-only and comes with a disc-specific DT Swiss wheelset and Shimano R785 hydraulic disc brakes so you can stop on a dime – even in the mud and snow.
Drivetrain: The Felt F3x ‘cross bike is spec’d with an 11-speed Shimano Ultegra drivetrain. Offering performance and value, Ultegra is the flank steak of road bike drive trains – it’s delicious and affordable. If that’s not good enough for you, or you want to upgrade down the road, the Felt designed the F3x frame to be electronic drivetrain-compatible, with built-in ports for Di2 wiring.
