Cannondale F-Si Hi-Mod 1 29" Mountain Bike 2020
The Cannondale F-Si HI-MOD 1 29" Mountain Bike is a genuine XC race weapon, upon which you can make yourself a podium contender from any start line. The lightweight Hi-MOD BallisTec carbon frame is both rigid and compliant in the right areas, so that power and comfort aren't compromised in the pursuit of glory. Then it's a who's who of performance components, from the ENVE carbon handlebar and seatpost to the full Shimano XTR groupset, and the build then being finished with lightweight HollowGram Hi-Impact carbon wheels.
The rear triangle uses SAVE technology that is engineered with a unique carbon layup for improved control and the integrated seat collar not only looks sleek, but further improves the ride experience. At the front, the standard-setting Lefty Ocho fork delivers control, agility and a smooth feel, with enough stiffness to encourage power when it's required. A 1X 12-speed drivetrain with a 10-51t cassette has the right gear for any situation, however steep the terrain, and the XTR Shadow Plus derailleur controls the chain and won't struggle to change gear even during intense race moments when you are going full gas.
