  • Specialized Ground Control Fat 26x4.6" tires roll over anything
  • Specialized FACT carbon fork w/ 5-inch tire clearance for stiff handling
  • Shimano Deore, hydraulic disc brakes w/ dual piston stopping power in all conditions
  • SRAM X0 Type 2, 10-speed, medium cage derailleur for crisp and reliable shifting
  • Custom e.thirteen, PF30, crankset w/ 100mm spindle delivers power and shifting precision
  • Fully butted M4 Premium Aluminum frame w/ up to 5-inch tire clearance is lightweight and stiff
