                                                                                              At just 900 grams, the F-Si Hi-Mod is the lightest mountain bike frame we’ve ever made. Better still, our engineers built in real compliance, real durability, and the handling and features that really win races.

                                                                                              F-Si attacks the steepest climbs and nastiest descents of modern World Cup XC courses. The Ai offset drivetrain and OutFront steering geometry deliver an uncanny mix of stability, agility and traction.
