Engineered for the most punishing conditions of cyclocross, the F1x is the pinnacle of the Fx family and the choice of World Champion Wout Van Aert. By removing the seat-stay bridge, Felt engineers were able to increase tire clearance while maintaining lateral stiffness from a wider BB386 bottom bracket. The frame is both incredibly responsive and exceptionally durable thanks to its UHC Advanced + TeXtreme construction, which features internal routing and comes equipped with a SRAM Force CX1 drivtrain with hydraulic disc brakes. Other top-shelf components include a Quarq Prime Carbon crankset, 3T handlebar, stem, and seatpost and DT Swiss wheelset with Schwalbe X-One tires.
