The Cannondale F-Si Hi-Mod 1 Hardtail Mountain Bike 2018 is quite like no other, designed to let you out-kick them on the climbs and out-rip them on the descents, this ultralight hardtail rocket is your ticket to the top of the podium. OutFront Steering Geometry gives the best of both worlds, slack and stable on hectic descents, yet quick and nimble everywhere else. Proprietary Ai offset drivetrain delivers super short chainstays for climb-winning traction and agile handling, without sacrificing mud/tyre clearance or limiting you to single ring set-ups. The F-SI Hi-Mod Carbon is stiff in all the right places thanks to an evenly-dished Ai rear wheel, super-short chainstays and BallisTec Hi-Mod Carbon construction. With its unbelievable rigidity and confident steering precision, Lefty out-corners, out-handles and flat-out rides circles around its flexy XC competition. To achieve the best possible fit for all riders, the size small frame is designed around 27.5 wheels, while M through to XL get 29 wheels.
