Cannondale F-Si Carbon 3 27.5″ Mountain Bike 2018 – Hardtail MTB



Cannondale’s F-Si Carbon 3 27.5” hardtail mountain bike is packed full of high-tech wizardry to help you reach the top step of the podium. Starting with the BallisTec carbon fibre frame, with Speed SAVE micro-suspension, the F-Si makes excellent use of Cannondale’s carbon fibre expertise to deliver a frame that’s lightweight, stiff, strong, and has a small amount of vertical compliance to help the rear wheel stay planted on rough ground. Up front, the F-Si Carbon 3 MTB features a Cannondale Lefty fork that is packed with advanced tech like the PBR Isolated Damper, tuned for XC+ riding. Between the bike and the ground lies a pair of 27.5” wheels. Lightweight and with a low rotational inertia, these help ensure you get the absolute best agility and handling response when tackling tight & twisty trails, and give you excellent manoeuvrability at all times.

If the F-Si Carbon 3 27.5” mountain bike is exactly what you’re looking for, but you would prefer a larger bike with 29er wheels, the Cannondale F-Si Carbon 3 29er mountain bike is available in frame sizes Medium, Large and X Large.
