The FX Sport SL 5 is a carbon fibre fitness bike for riders who want the speed of a lightweight road bike with the comfort and control of a flat handlebar. It steps up to an 11-speed SRAM Apex 1x drivetrain with a wide 11-42 cassette, and keeps the 400 Series OCLV Carbon frame, carbon fork, hydraulic disc brakes and tubeless-ready rims, making it ideal for everything from solo workouts to fast group rides.
