The Ouroboros CR is a carbon drop-bar bike for riders who split their time between gravel and mountain bike trails, and want one bike that's properly at home on both. It's light and lively enough for fast gravel, but built around the things that matter when the ground gets rough: big tyres, big rotors, a dropper post and a wide gear range.
The carbon frame pairs with a 40mm-travel Fox AX32 suspension fork with GRIP damper, which takes the sting out of rough gravel and rooty singletrack, and the frame is UDH equipped and ready for SRAM Transmission. Shimano GRX 820 levers and brakes work with a Deore 10-51t 12-speed cassette and GRX derailleur, while 180mm rotors give real stopping power on long, loose descents.
WTB Resolute 700x50 tyres on WTB KOM Team i27 rims add grip and comfort, and a TranzX dropper lets you get low and loose when the trail demands it. For 2027 it comes in Gloss Metallic Silver.
