Internal derailleur routing
Sleek ports at the head tube and near the seat tube let you route your derailleur cables through the frame to keep your bike running smooth and clean.

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.
