The F40x is race-ready for any cyclocross course, but it can also double down as a capable bike for any road ride, daily commute or adventure ride. Its rugged FLite custom-butted aluminum frame is paired with a carbon fiber fork to mitigate bumps and front-end vibrations, while its oversized bottom bracket makes for a stiff and ultra-efficient pedaling platform. The F40x also features a Shimano Tiagra drivetrain, Shimano hydraulic disc brakes, and tubeless-ready wheels, so it’s ready to jump the barriers, seek out undiscovered roads or tackle the urban commute.
