"Overall, we loved our time on the Speed Concept. The improved comfort, storage features and adjustability alone make it worth the wait over the previous version. Add in the claimed speed benefits, and you have a superbike that’s up there with the very best in 2022."

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.
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.
