On Cannondale's F-Si Carbon 1, speed simply happens. The HI-MOD Ballistec carbon frame features Cannondale's breakthrough Asymmetric Integration rear triangle and drivetrain, delivering super short chainstrays, an optimally dished rear wheel, and tons of mud clearance. New-school System 29 geometry redefines XC handling and speed, showcasing agility and handling in switchbacks or 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 your. 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 tubless-ready Mavic CrossMax SLR 29er wheels, Cannondale's own stellar aluminum and carbon components, and a sleek Fabric Scoop saddle keeping the F-Si Carbon 1 race-day-ready.
