Ouroboros CR 2026

The Kona Ouroboros CR is an all-new platform from the unbound minds at Kona.  Pack it expertly for the long haul, nimbly explore the edges of singletrack, or complete multiple days of the most wonderfully weird and delightfully chaotic of events. While other gravel bikes may technically tolerate mountain bike components, the Ouroboros is intentionally designed around the rowdy stuff – like 180mm rotors, 2.1 tire clearance, and front suspension, giving you a ride feel that is otherworldly and almost mistakable for a modern trail bike.

Whether you’re a gravel-loving mountain biker or a mountain-bike-loving gravel biker, the Ouroboros Carbon is the lure to catch the attention of both. Kona made sure each coin spent is met with corresponding value in shred performance. The Ouroboros Carbon is meant for big things, so we put big things on it – like fat tires, large rotors, a mountain standard dropper post width, and a low, yet wide gear range. Hop on and let the journey unfold.
