    Leaving little to be desired, the Cannondale F-Si Carbon 1 hardtail mountain bike has lightness at its core. Cannondale have turned to their top-grade BallisTec Hi-MOD carbon fibre to build the F-Si Carbon 1 MTB, and the result is quite impressive. The frame is unbelievably light and stiff, and that makes it super agile to ride. Cannondale have engineered in their Speed SAVE micro-suspension technology to help give the bike extra smoothness and impact absorption over rough ground – you’ll really feel the difference when you hit those unexpected braking ruts. 29er wheels play their part in ironing out the fined lumps & bumps in the trail surface, and the Lefty 2.0 100mm suspension fork ensures the front wheel stays in contact with the ground at all times.

    Key Features:

    • BallisTec Hi-MOD carbon fibre, with Asymmetric Integration, and Speed SAVE micro-suspension
    • Cannondale Lefty 2.0 Carbon 100mm fork, with 2spring and PBR Isolated Damper, tuned for XC racing
    • Shimano XT/XTR Di2 1x11 speed gearing delivers rapid 7 effortless electronic gear shifting
    • Shimano XT disc brakes with 160mm Ice-Tech rotors give you unprecedent levels of braking control
    • Sizes: Small (27.5” wheel), Medium (29er), Large (29er), X Large (29er)
    • Colour: Acid Red/Jet Black
    • The Cannondale F-Si Carbon 1 hardtail mountain bike is available with 0% APR finance
