Features /

Domane 4 Series flies past any other carbon endurance race bike in its class, with IsoSpeed for race comfort, endurance geometry for stability, and Power Transfer Construction for speed.


Project One

Our exclusive custom bike programme. You dream it, we build it.

400 Series OCLV

Ultra-high performance, within reach. The areal weight range and modulus mix of 400 Series OCLV provides an exhilarating sense of acceleration and confident handling.

Endurance fit

As befits Domane, the world’s most advanced endurance racing bike, we’ve developed the world’s most comfortable racing geometry. Still racy, but with a slightly higher head tube.

Endurance geometry

Performance. Stability. Victory. Domane endurance geometry is a triple threat, maximising control, handling, and responsiveness through perfectly tuned rider weight bias.

IsoSpeed decoupler

A technological revolution. IsoSpeed isolates the seat tube from the rest of the frameset, doubling compliance and comfort with zero performance drawbacks.

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.

Power Transfer Construction

Trek Power Transfer Construction puts more power to the road by optimising the head tube/down tube/bottom bracket/rear wheel connection.

E2 head tube and fork

E2 head tube tapers from a 1.5" lower to a 1-1/8" upper, placing more material where it matters most for the lateral rigidity of a 1.5" system without the added weight.

Vanishing mudguard mounts

Discreet mounts accommodate full-coverage mudguards for added utility.

3S integrated chain keeper

Our 3S chain keeper is integrated directly into the bike frame. It's an elegant solution that provides flawless gear shifting even on rough roads and under heavy loads.

Direct-mount front derailleur

Provides accurate gear shifting in a lightweight, minimal package.

DuoTrap compatible

DuoTrap seamlessly integrates the computer sensor into the frame to measure speed, distance, and cadence with no added aerodynamic drag.

Crank: compact

Two front chainrings with shorter gearing, for the best combination of climbing ability and flat-terrain speed.

10 speed

The standard in race-performance gearing.
