Technical Specifications
With a plush SR Suntour fork featuring lockout, powerful Tektro hydraulic disc brakes, and double-walled 29-inch alloy wheels, the Hardrock Sport Disc is prepared for mountain trails and urban jungles.

  • Specialized Fast Trak Sport tires use Adaptive Tread Technology for lower rolling resistance, but have plenty of grip for confidence on the trail
  • SR Suntour XCT crankset with Shimano Acera rear derailleur and 8-speed Sunrace cassette offers a wide range of gear selections and reliable shifting
  • Tektro hydraulic disc brakes/levers with Light Wave rotors create increased control and superior stopping power for more confident braking
