All the fun of a fat bike with the performance of a Specialized, what more could you ask for?! The 2015 Specialized Fatboy Fat Bike combines a lightweight M4 premium aluminum frame and a carbon fork with 4.6 inch Specialized Ground Control tires for nimble handling in the most extreme conditions. Add in Tektro Draco 2 hydraulic disc brakes, and a Sram 2x10 drive train and you have a high performing dream of a fat bike.

  • New, full monocoque, Specialized FACT carbon fiber fork with 5-inch tire clearance is super-lightweight and stiff
  • Wide, 4.6 inch Specialized Ground Control tires with foldable aramid bead are light, fast rolling, and provide excellent traction regardless of the terrain
