F-Si bike cannondale 2019


If your life revolves around the quest for podiums; if you weigh, measure and analyze every element of your preparation, if your idea of fun is turning yourself inside out till your eyes bleed and your competitors drop; basically, if you’re obsessed with XC, the all-new F-Si is the bike for you. Built to climb faster, descend harder, and sprint better than any other hardtail out there, it’s serious XC goodness for those with serious XC issues.

The fastest, best climbing, best descending XC hardtail on the market.


One of the lightest XC hardtails in the world, the new F-Si is over 300g lighter than the previous version. Frame shaves 70g and the new Lefty Ocho chops a whopping 250g.


Slacker head angle than previous F-Si adds even more stability and control on sketchy descents. Custom 55mm long fork rake on the Lefty Ocho keeps handling precise and agile at slower speeds.


Ai offset drivetrain delivers even shorter chainstays than the original, for climb-winning traction and agility, with clearance for big tyres, 2x chainring compatibility and a stiffer, stronger rear wheel.


Reach to the head tube is increased slightly for improved control. An integrated seat binder looks super clean and exposes more seatpost length for improved comfort.


New race-tuned stiffness keeps things stout where needed for power transfer, but adds even more bump-eating comfort so you can go harder longer
