Like a cat running for the door when its open, we encourage you and your fatbike to escape to the local groomed single track to feel the thunder and bite that is - Dunderbeist. The 45 North Dunderbeist Fatbike tire plants a 4.6" paw print into the snow, providing enhanced traction and flotation while the aggressive tread delivers unparalleled acceleration and braking traction. Pair Dunderbeist with its sibling front tire, Flowbeist, for the ultimate combination of traction and control.
