Endurance fit
As befits the world’s most advanced endurance racing bikes, we’ve developed the world’s most stable racing geometry. Still racy, but with a slightly higher head tube for better stability and greater comfort through the entire ride.
Endurance geometry
Performance. Stability. Victory. Trek endurance geometry is a triple threat, maximizing control, handling, and responsiveness through perfectly tuned rider weight bias.
Fender compatible
Fender mounts allow for full-coverage fenders so you can ride comfortably in less-than-ideal conditions.
IsoSpeed fork
It's a one-two punch: generous ride-tuned sweep and shape increases compliance for a smoother ride, and unique dropout placement optimizes the wheelbase.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
Additional Tire Clearance
Additional tire clearance allows Domane to go where no road bike has gone before. Race, ride, explore.

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.
