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.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
