Please select options


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 chainstays, 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 you. Shimano and SRAM team up to give the F-Si Carbon 1 a fast, smooth 20-speed drivetrain with gears for the ups and downs of any race. Matched to Cannondale's own Hollowgram Si crank with a pair of FSA chainrings, 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 Fabric Scoop saddle keeping the F-Si Carbon 1 race-day-ready.

This bike is absolutely the best feeling bike i have ever had! it feels like all this time i have been riding good bikes but this bike just feels like your cheating and you have an advantage. I have way more confidence with this bike i can go into corners faster then ever before and i can go in to a really technical rock garden or a bumpy section this bike just floats through it with no flex in the front end because of the lefty which it great to feel and this bike isn't a hard tail it is a soft tail you get flex in the back triangle of the frame up and down and not side to side which feels great in the rock garden, nice and soft and nice to push a corner fast and keep that line. i have never ridden a bike like this and i won't go back i am set.
