Kona Ouroboros

The aluminum Ouroboros is impressively capable, with componentry that is unwavering in reliable performance. Designed with the intention to stay off the grid, escape into the wilderness – worry free. We took the best parts of our award-winning gravel bikes, and the enchanting characteristics of our iconic mountain bikes, and delivered a drop bar bike that doesn’t rip by accident. Shred on, dear traveler, and let nothing hold you back.

Built around a robust Kona 6061 butted aluminum frame, this version of the Ouroboros blurs the line between gravel and mountain. It features a bump-eating Suntour GVX32 40mm suspension fork, a reliable Microshift Sword 1x10 drivetrain, a TranzX dropper post, and massive 700x50c Maxxis Ravager tires to keep you planted on the rowdiest terrain.

 

Key Features:

• Mountain Bike DNA: Equipped with a 125mm TranzX dropper post, wide 20-degree flared gravel bars, and mountain-bike-sized 180mm TRP brake rotors, this bike is built to confidently tackle steep descents and technical singletrack.

   

• Front Suspension: The Suntour GVX32 fork provides 40mm of travel to absorb harsh impacts, reduce hand fatigue, and keep your front wheel tracking smoothly over rocks, roots, and washboards.

   

• Microshift Sword Drivetrain: Purpose-built for drop-bar off-road riding, the 10-speed drivetrain pairs a 40t chainring with an 11-48t cassette for incredible climbing range, while the clutched derailleur keeps your chain secure through the rough stuff.

   

• Massive Traction: High-volume 700x50c Maxxis Ravager tires mounted to wide WTB ST i27 tubeless-ready rims provide incredible grip, floatation, and puncture resistance when the trail gets loose and chunky.

   

• Limitless Bikepacking Potential: With its durable butted aluminum frame and comfortable upright geometry, the Ouroboros is ready to be loaded up with bags and gear for your most ambitious off-grid overland adventures.
