Will my bike have a curved top tube?
Size Small frames have a top tube that dips down as it approaches the seat tube. This makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders typically don't have the same issues.
Blendr stem
Bontrager stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.

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.
