Trek Speed Concept Slr 7 Axs Road Bike
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
