Features /

Speed Concept 9 Series has opened up its lead. It features cleaner, more complete integration, even better performance at low yaw angles, and it's nearly a pound lighter.


11 speed

The new pinnacle of gear shifting performance.

Project One

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

New, faster frame design

Speed Concept was already the fastest bike in the world, and our latest improvements make it even faster.

600 Series OCLV

Advanced aerospace materials and weight-saving, performance-enhancing technology provide the best frame weight/stiffness combinations in the industry.

WSD: fit for women

A great-fitting bike is a joy to ride. The better the fit, the greater your comfort, stability, power, and control. And nothing fits better than Trek WSD, Women’s Specific Design.

The fastest fit

Nothing fits like Speed Concept, thanks to the best fit window in the industry. You'll feel the difference, from the bike leg through to the finish line.

Speed geometry

Tri-specific geometry provides ultra-stable handling when you're in the aero bars, for a more confident ride.

Ultra-clean front end

Incredibly svelte! Fully integrated handlebar with hidden gear shift and brake cables presents 30% less surface to the wind. The lightest, cleanest, most aero front end ever.

Integrated Speed Storage

Bontrager integrated Speed Storage products are so well fitted to the Speed Concept frame that you and your bike are actually more aerodynamic with them than without.

Full-foil fork

We tested every shape possible in the wind tunnel and on the course in pursuit of this no-holds-barred full-foil aero fork.

KVF tube shape

Kammtail Virtual Foil is the most aerodynamic tube shape ever designed for a bicycle. And now it's even faster, with less frontal area and reduced drag at all yaw angles.

Integrated handlebar

Bar is integrated into the frame for the sleekest, lowest-drag profile.

Invisible brakes

Speed Concept is the first bike with front and rear brakes built directly into the fuselage. This innovative setup results in less drag and cleaner lines.

Speed Fin

Our exclusive Speed Fin boosts braking power and improves aerodynamics.

Electronic drivetrain optimisation

No cable ties, no electrical tape, just the cleanest electronic drivetrain integration available on a tri bike.

Direct-mount front derailleur

Provides accurate gear shifting in a lightweight, minimal package.

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.

DuoTrap compatible

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

Bontrager aero skewers

Even the quick-release skewers on the Speed Concept increase its speed. We integrate them into the shape of the bike for faster aerodynamics.
