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.



Integrated power meter
This bike helps you get the most out of every ride with a SRAM power meter that measures your input and provides accurate data, allowing you to track your progress and tailor your training to crush your goals.

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.
