At just 900 grams (size Med, with all paint and hardware), the all-new F-Si is the lightest mountain bike frame Cannondale has ever made. It shaves 80 grams off the previous F-Si, and when you factor in the svelte new Lefty Ocho, you save a whopping 330 grams on the frame and fork (that's around 3/4 of a pound for you imperial folks). Pretty impressive.
What’s even more impressive is that, rather than chasing marketing grams, our engineers focused on features that deliver real performance benefits out on the course. Features like Ai and OutFront, or improved compliance, or improved durability. That’s what wins races, not saving the weight of a few sips of water. Lighten up right, with the all-new F-Si.
