On Cannondale's F-Si Hi-MOD 1, speed simply happens. The Hi-MOD Ballistec carbon frame features Cannondale's breakthrough Asymmetric Integration rear triangle, delivering super short chainstays, an optimally dished rear wheel, and tons of mud clearance. New-school System 29 geometry redefines XC handling and speed, showcasing agility, handling, and go-fast prowess in switchbacks and while attacking rough terrain at high speeds. With a 1.5-inch head tube and Cannondale's Lefty 2.0 Carbon XLR fork featuring 100mm of plush suspension travel, keeping your front wheel pinned to your line is easy no matter what the trail throws at you. Shimano's XT/XTR drivetrain gives the F-Si Hi-MOD 1 a fast, smooth 22-speed drivetrain. It's propelled by Cannondale's own Hollowgram Si crank with a pair of FSA chainrings, so putting the power down and leaving the competition behind will become the standard. Shimano's XT brakes have a deservedly high reputation, with power to spare and unmatched real-world performance. The rest of the spec is just as performance-minded with tubeless-ready Mavic CrossMax SLR 29er wheels, Cannondale's own stellar aluminum and carbon components, and a sleek Prologo Nago Evo X8 saddle making sure speed simply happens.
