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.
