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 throughout the entire ride.
Endurance geometry
Performance. Stability. Victory. Trek endurance geometry is a triple threat, maximising control, handling and responsiveness through perfectly tuned rider weight bias.
Mudguard compatible
Mudguard mounts allow for full-coverage mudguards 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 optimises the wheelbase.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
Additional Tyre Clearance
The additional tyre clearance allows the Domane to go where no road bike has gone before. Race, ride, explore.
