Cannondale F-Si HiMod 1 Mountain Bike 2021 - Hardtail MTB
Light, but it's no lightweight.
A pure XC race mountain bike. Loaded with performance features that ensure victory, all while weighing next to nothing.
Key Features:
- Speed Release
A faster, better thru-axle. The slotted dropout design lets the axle stay in the hub for quicker, easier wheel changes. Compatible with standard 148x12 thru-axle hubs. It’s a better way thru.
- Traction Without Compromise
Proprietary Ai offset drivetrain delivers super short chainstays for climb-winning traction and agile handling, without sacrificing mud/tire clearance or limiting you to single ring set-ups.
- Agility Meets Stability
Confidently stable on hectic descents, yet quick and nimble everywhere else - OutFront Steering Geometry gives you the best of both worlds.
- BallisTec Hi-MOD Carbon
Cannondale's premium high-strength, high-stiffness carbon construction. An advanced blend of intermediate, high, and ultra-high modulus fibers yields a frame that’s extremely light, durable, and lively.
Occasionally, without notice, manufacturers change product design and/or specifications.
