H2 fit

H2 is the optimal fit to put most riders, including many of our Pro Team athletes, in the right position for power and performance.

Invisible weld technology

Revolutionary welding technology creates a better connection with each tube junction, increasing strength while using less material.

Sizing & fit

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 Trek retailer.
