Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8?, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
