The Great Bear, Titanium-ified

Why We Love It
The Chumba Ursa Major is a fast fat bike you can ride year around whether you're in deep, powdery snow, singletrack or in the backcountry. The USA made titanium frameset is designed with relaxed geometry and short chainstays that make for a stable, yet nimble ride. With 5.0" tire clearance, sliding rear dropouts and space for 4 water bottles the Ursa Major is a true adventure bike.
