All the fun of a fat bike with the performance of a Specialized. The Fatboy Pro combines a lightweight frame, RockShox Bluto fork, and 4.6" Ground Control tires to create a geometry similar to Specialized 29er geometry for nimble handling in the most extreme conditions.
  • Fat 26" disc, alloy single wall rims are designed to handle even the worst terrain
  • Specialized Ground Control Fat 26x4.6" tires roll over anything
  • Race Face Next SL crankset w/ 100mm spindle is built for power no matter the terrain
  • Shimano XT, hydraulic disc brakes w/ Ice Tech pads and rotors for max stopping power
  • SRAM X0, 11-speed derailleur w/ carbon cage for reliable and precise shifting
  • Fully butted M4 Premium Aluminum frame w/ up to 5-inch tire clearance is lightweight and stiff
  • RockShox Bluto RL Solo Air spring shock w/ TurnKey damping for traction in all conditions
