Heyday! C Deore 12 is the best fat-tire bike for off-track adventures. Its 26 x 4.6″ tires float over snow, sand, dirt…you get the idea. Stable geometry (with Alternator dropouts) and a lightweight carbon frame and fork help you overcome anything in your path. And if your path is long enough to keep you out all day — or more — frame and fork cargo mounts give you plenty of places to stash food, water, layers, and camping gear. Top it off with Shimano’s wide-range Deore 12-speed drivetrain, and you’re ready for just about anything you can put your imagination to.
