Discover your true potential. The Cannondale F-Si Carbon 5 29er mountain bike is an XC race machine with victory in its veins. Built around a BallisTec carbon frame, with Speed SAVE micro-suspension and an Ai (Asymmetric Integration) rear triangle, the F-Si is both incredibly lightweight and agile, without sacrificing an ounce of strength. In fact, the Ai system allows the F-Si hardtail MTB to boast as much as 60% increased stiffness at the rear wheel, and the shortest chainstays in its class. Add to that the smooth-rolling 29er wheels, 100mm travel fork, and wide-range gears, the result is a cross-country race bike with incredible trail manners and unrelenting traction in the climbs, with handling that lets you overcome any obstacle on the descents.
Also available with a 27.5” wheel in the Small frame size, check out the Cannondale F-Si 27.5” hardtail mountain bike.
A race hardtail like no other. Designed to let you out-kick them on the climbs and out-rip them on the descents, this ultralight rocket is your ticket to the top of the podium.
