The Cannondale F-Si has always been about pushing the limits of what an XC hardtail is capable of, & the new version pushes it harder & further than ever. No other hardtail descends as fast, climbs as nimbly, or kicks harder, smoother. With the otherworldly performance of the new Lefty Ocho, youve got a whole-new level of XC capability, tailor-made to feed the needs of the XC obsessed. At just 900 grams, the all-new F-Si is the lightest mountain bike frame Cannondale have ever made. It shaves 80 grams off its predecessor, & when you factor in the svelte new Lefty Ocho, you save a whopping 330 grams on the frame & fork. Whats even more impressive is that, rather than chasing marketing grams, Cannondale engineers focused on features that deliver real performance benefits out on the course
- features such as Ai & Out Front, or enhanced compliance or enhanced durability. Thats what wins races, not saving the weight of a few sips of water. The all-new Lefty Ocho is the smoothest, stiffest ultra-light XC fork ever made. It floats through chop & steers through the choss like nothing else. Short chainstays do wonders for traction & nimble handling, but they usually come at a cost. Not with Ai
- this proprietary Asymmetric Integration drivetrain offset moves the gears & rear triangle over, helping creating space for much shorts stays while still having the clearance for big tyres & 2x drivetrains if you so desire. It even creates a stiffer, stronger rear wheel by evening out the dish.
