    Don’t be fooled by its unassumingly simple appearance – the Cannondale F-Si Carbon 4 29er hardtail mountain bike is every bit the tech-packed XC race bike. Using Cannondale’s own BallisTec carbon fibre, with in-built Speed SAVE micro-suspension, the F-Si MTB boasts an incredibly lightweight, stiff, strong, and surprisingly comfortable frame. Cannondale’s famous single-sided Lefty fork comes complete with 100mm of travel and PBR isolated damper technology with an XC+ tune, giving it impeccable poise and control over rough ground. Talking of rough ground, the 29er wheels help smooth out the trail with their reduced rolling resistance. Coupled with the 2x11 speed gears, super-stiff Asymmetric Integration rear triangle, and the shortest-in-class chainstays, and you’ve got a bike that could lead you to your next race win.

    For shorter riders who prefer a 27.5” wheel, there’s also the Cannondale F-Si Carbon 4 27.5” hardtail mountain bike, available in a Small frame size.

    Key Features:

    • BallisTec carbon fibre frame, with Speed SAVE micro-suspension and Asymmetric Integration
    • Cannondale Lefty 2.0 100mm fork, with 2spring and PBR Isolated Damper technology, tuned for XC racing
    • Shimano SLX/XT 2x11 speed gears give you an incredible range for climbing and descending
    • Shimano Deore MT500 hydraulic discs with 180mm rotors deliver ample stopping power for any trail
    • Sizes: Medium, Large, X Large
    • Colour: Jet Black/Neon Spring Gloss
    • The Cannondale F-Si Carbon 4 29er hardtail mountain bike is available with 0% APR finance
