It was hard to resist showing a complex formula to illustrate how our widest gear ratio options allow you to conquer every type of terrain. But that wouldn’t have made you feel any better, would it? So we decided not to. But then again, a gear range of 612% is pretty impressive.
It’s tight and precise. Designed to withstand full force pedalling on the roughest trails, while shifting gears as smooth as ever. Our best chain stability yet, though we do expect to drop some stokage on you from its performance.
