Description

The Speed Concept SLR 7 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.

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 ultra-light 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 customisable, 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.
