The Ouroboros CR is a carbon gravel bike designed around the rowdy stuff. Pack it for the long haul, nimbly explore the edges of singletrack or take on multi-day events, and it will feel more like a modern trail bike than a typical gravel machine.
Where many gravel bikes merely tolerate mountain bike parts, the Ouroboros is built around them: 180mm rotors, generous tyre clearance and a 40mm Fox TC32 suspension fork. It's fitted with fat 700x50c Maxxis Ravager tyres, a mountain-standard 31.6mm TranzX dropper and a low, wide-range SRAM Apex Eagle 12-speed drivetrain with an 11-50t cassette, so it's ready for steep climbs and loose descents alike.
Whether you're a gravel-loving mountain biker or a mountain-bike-loving gravel rider, it's a bike that encourages you to go further and ride rougher.
