The Ouroboros is a mountain-bike-inspired gravel bike that's a real blast on rough off-road trails. It takes the best parts of Kona's gravel range and blends in the character of the brand's mountain bikes, resulting in a drop-bar bike that's happy to leave the tarmac far behind.
The butted aluminium frame is paired with a Suntour GVX32 suspension fork offering 40mm of travel to take the edge off rough tracks, and a TranzX dropper post lets you get low and loose on descents. Microshift Sword 1x10 with a 40t ring and 11-48t cassette keeps things simple with plenty of range, and TRP Spyre C brakes with 180mm rotors at both ends give consistent control. Big 700x50c Maxxis Ravager tyres on wide WTB i27 rims add grip and comfort.
It's designed for getting off the grid and exploring with confidence. Pedals are not included.
