There are all other carbon triathlon bikes... and then there’s Speed Concept 9 Series. Real-world wins confirm wind tunnel predictions: 9 Series is the fastest bike on the planet.


600 Series OCLV

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

KVF tube shape

Kammtail Virtual Foil. It’s the most aerodynamic tube shape ever designed for a bicycle.

DuoTrap compatible

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

Integrated handlebar

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

BB90: light and fast

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.

Draft Box compatible

Bontrager's puncture repair storage fits the Speed Concept frame so well that the bike is actually more aerodynamic with it than without.

Speed Box compatible

Bontrager's super-aero top tube nutrition storage fits the Speed Concept frame so well that the bike is actually more aerodynamic with it than without.

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.

Integrated front brake

Brake is integrated into the fuselage for the lowest possible aero drag. A Speed Concept exclusive.

Integrated rear brake

Brake is integrated into the frame for minimal drag and maximum efficiency.

Internal cable routing

Shift and brake cables are routed through the frame for the lightest, cleanest, best cable management ever.

Electronic drivetrain optimisation

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

Super-stable tri geometry

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

The fastest fit

The Speed Concept was developed for the absolute fastest riders in the sport, but with every rider in mind. No other brand has a wider range of sizes or a more adjustable fit.

Project One

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

Leading-edge technology

Presenting the least amount of surface area at the front of the bike is crucial. It sets the tone for how the rest of the bike will perform.

Wind tunnel data

Trek spent thousands of hours in the wind tunnel applying real-world wind conditions to Speed Concept and our competitors. The results speak for themselves.

StepJoint Technology

StepJoint Technology bonds two carbon structures together perfectly, with no overlap, no excess carbon, and consistent tube wall thickness throughout. Only from Trek.

Direct-mount front derailleur

Provides accurate gear shifting in a lightweight, minimal package.
