Cannondale's proprietary BallisTec carbon lets them push boundaries and tune rigidity throughout the entire frame – for stiffness where you need it and compliance where you don't. So durable that Cannondale backs it with a lifetime warranty.
For seated comfort, designing the F-Si with a 27.2mm seatpost was just the start. The collarless seatpost clamp takes it even further, lowering the clamping point so that more of the post can flex.
A faster kind of thru-axle. Slotted dropout design lets the axle stay in the hub for quicker, easier wheel changes.
