Cannondale F-Si Carbon 3 29" Mountain Bike 2020
The lightweight hardtail Cannondale F-Si Carbon 3 29" Mountain Bike is fine-tuned for thrashing the XC race course. The proprietary BallisTec carbon frame is both stiff for power whilst also being compliant in the right areas and the unique layup of the SAVE rear triangle delivers comfort and control. Up front, the eye-catching Lefty Ocho balances form and function, offering 100mm of smooth travel in a stiff and responsive package so that the front wheel feels agile and obedient. Internal cable routing keeps the look sharp and clean, as well as reducing wear on vulnerable parts of the build and there's an integrated wheel sensor for accurate tracking of all aspects of your activities.
A 12-speed SRAM GX Eagle 1X drivetrain with 11-50t cassette offers plenty of range for any terrain and the SRAM Level T hydraulic brakes provide capable stopping performance no matter the conditions. The bike rolls on Stan's NoTubes 29" wheels with assured traction from the Schwalbe tubeless-ready tyres.
