2024 Trek Bicycle Speed Concept SLR 9 XL

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.

Features may include:

• Fast aero shapes

This Speed Concept is the fastest bike we’ve ever tested—and it’s six minutes faster than the previous model at Kona. The ultralight 800 Series OCLV Carbon frame’s drag-reducing Kammtail Virtual Foil tube shapes cut through the air.

• Smart storage

Integrated fuel and hydration storage makes it simple and stress-free to stay strong without leaving your aero position.

• Dial in the perfect fit

Our system is designed to fit as many triathletes as possible. It’s fully customizable, simple to adjust, and preserves your fit while you travel

• Smooth ride

Top Tube IsoSpeed takes the edge off rough roads, keeping you fresher and less fatigued not only on your ride, but on your run as well.

• Shimano Dura-Ace Di2

The pinnacle of Shimano road technology and innovation, the new 12 speed Dura-Ace Di2 R9200 is Shimano's fastest ever. Speed was the driving force behind this next-generation road group. That’s why every component was refined, designed, and fine-tuned to make you faster – whether you’re sprinting to the finish on the Champs-Elysees or crushing your local climb.

• Don’t forget your pedals

This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.
