Trek Road Bikes Size Chart
*Bike and frame are based off pre-production painted frames at time of publication. Weights may vary in final production.
**The chart below shows TREK's 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 their 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 Scheels.
