The ride, not just the specs
Speed Concept is made for one job: getting you from the start to the finish as fast as possible. It's the bike for triathletes and time trialists who train with a goal in mind.
We'd love to help you dial in the fit, because on a bike like this, fit is speed.
What makes it special
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.
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
Perfect fit, the first time. When you buy a Speed Concept frameset, size-specific proprietary components like the seatpost and cockpit parts are sold separately to ensure you get the right parts for your unique measurements.

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.
