Project One

Our exclusive custom bike program. 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.

H2 fit

The right fit for most riders. Our classic H2 fit has a slightly higher head tube to put less strain on your back and neck.

KVF fork

Aero fork legs minimize drag, while increasing lateral stiffness for ultimate speed, comfort, and precise handling.

KVF head tube

Super-aero head tube is optimized at the leading and trailing edges for minimum drag.

KVF tube shape

We’ve optimized our revolutionary KVF tube shape to give you the stiffness and comfort you expect from Madone in an even lighter, more aero package.

Performance cable routing

Our sleek, race-optimized cable routing system virtually eliminates friction for the crispest shifting in any conditions. Three years in the making, and well worth the wait.

Electronic drivetrain integration

No zip ties, no electrical tape, just the cleanest electronic drivetrain integration available.

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 fender mounts

Discreet mounts accommodate full-coverage fenders for added utility.

BB90

BB90 is the widest bottom bracket available on a road bike. This Trek-exclusive carbon BB makes the frame lighter, stiffer, and quicker to accelerate.

3S integrated chain keeper

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

Direct-mount front derailleur

Provides accurate 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.
