Speed Concept SLR 9 is an aerodynamic carbon triathlon bike engineered for incredible speed and seamless integration. Every bit of this bike-from the light aero frame to ride-smoothing IsoSpeed to cutting-edge fuel and hydration systems-has been painstakingly designed to help you beat your PR again, and again, and again.

It's right for you if…
You leave it all on the course and want a tri bike that does the same. You want blazing fast aero speed, a Shimano Dura-Ace wireless electronic drivetrain for precise shifts, and loads of integrated accessories that make hydrating and re-fueling easy.

The tech you get
Ultra-lightweight 800 Series OCLV Carbon frame, drag-reducing Kammtail Virtual Foil (KVF) tube shaping, Speed Concept full foil carbon fork, road-smoothing IsoSpeed, integrated fuel, hydration, and flat kit storage, Shimano Dura-Ace wireless electronic 12-speed drivetrain, fully integrated handlebar and stem, Bontrager Hilo Pro Carbon triathlon-specific saddle for an aggressive aero position, disc brakes for reliable stopping power, and aero Bontrager Aeolus RSL 51 OCLV Carbon wheels.

The final word
Speed Concept is as fast as it is smart. Its simple, thoughtful design and integrated features ensure a less stressful race day, help you achieve your fastest bike splits ever, and set you up for a successful run. SLR 9 also gives you the performance boost of Shimano's best drivetrain and high-end Bontrager carbon wheels.

Why you'll love it:
- Smart integrated fuel and hydration storage makes it simple and stress-free to stay strong without leaving your aero position
- Top Tube IsoSpeed takes the edge off rough roads and is damped with an elastomer so it rebounds in a smooth, controlled, stable motion
- Easy build, easy travel: fast assembly makes it easier to travel to races
- All-new wireless Dure-Ace Di2 delivers ever faster, smoother, and more responsive shifts than ever
- Make it yours: it's fully customizable through Project One. Choose your model. Choose your paint. Choose your parts.
