You know who you are. You don't fear the term "oxygen debt", you don't mind getting mud on everything, and you've occasionally mistaken the ringing in your ears for cowbells. Felt created the F55X just for you. This race-ready 'cross machine satiates your needs with an agile aluminum frame and carbon fork that hold your line, damp the ruts, and leave you looking to move up the ranks when the bell lap tolls. The components are race-ready, too, with a 11-speed Rival Cx1 drivetrain powering Felt's own CxR3 rims via SRAM cranks. Tacky Schwalbe tires give you serious grip and Felt's aluminum components round out a ride that's ready for prime-time domination.
