Kona Ouroboros CR

The Ouroboros CR is a high performance carbon gravel bike built for rough terrain, ambitious bikepacking routes, and riders who expect more from a drop-bar bike. Whether you’re a gravel-loving mountain biker or a mountain-bike-loving gravel biker, the Ouroboros Carbon was made to get your attention. Its lightweight carbon frame is paired with fat tires, large rotors, mountain-bike-standard dropper compatibility, and a wide gear range to deliver real control and capability when the riding gets rowdy. Every part earns its place—and every dollar earns its share of shred. Hop on and let the journey unfold.
