An Ye Harm None, Do What Ye Will 

The Ouroboros is an all-new platform from the unbound minds at Kona. We bring you four builds – each meant for its own incredibly rowdy ride to the ends of the earth and back. 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, massive tire clearance, and front suspension, giving you a ride feel that is otherworldly and almost mistakable for a modern trail bike.

An absolutely stunning gravel bike for those who seek a more traditional look and feel. This creation prioritizes lightweight features and adheres to the sacred and long-established characteristics of a drop bar bike. We’ve thoughtfully spec’d gear steps that are closer together to help you maintain your ideal cadence. With that sweet spot so easy to find, you won’t lose your rhythm – no matter your load or speed.

Features

• 5 Frame Mounting Points
  Located in the front triangle, these boss mounts allow for limitless custom frame bag options devoid of straps.
• 69.5° Headtube Angle
  Slacker than gravel, steeper than modern trail mountain bikes, we chose this angle for a reason. This angle keeps enough weight on the front wheel to keep things snappy on slappy singletrack, yet relaxed enough to not send you kissing the front tire when things get beguiling. 
• Wider Tire Clearance
  In the never-ending quest to run slightly wider tires just because we said you can, we've broadened the horizons of the rubber fitment journey. Run a 29x2.5" front tire with the carbon rigid fork or run a 700x50mm front tire with a Fox, RockShox, or Suntour 40mm suspension fork. 
• 31.6mm Seatpost
  This. This is a moment of genuine intention. Look past the typical 27.2mm dropper posts and you'll see it. As hardcore riders designing for hardcore riders, we know how the longevity of a dropper is crucial when you're deep in those backcountry moments — only a proper 31.6mm seatpost can ensure riders are able to choose what keeps them going for the long haul.
