Fuji's Wendigo is a roll-over-anything tank that's an absolute blast to ride. It was created to go where normal mountain bikes flounder with nearly 5-inch-wide tires on 26-inch wheels. The flotation and traction gained by using large volume, low-pressure tires can get you over and through otherwise unrideable terrain: ice, snow, sand, mud, wet rocks and roots. The drivetrain is ready for anything, too, with Shimano Deore derailleurs, wide-range gears, and a burly aluminum crankset. To help you master the most adverse conditions, you get tough Oval Concepts components as well as Tektro hydraulic-disc brakes.
