Better than ever after all these years, our Hardrock is still the best performing mountain bike in its class ... and for good reason. With its lightweight frame, stable geometry and outstanding specification, no other entry-level hardtail on the market can match this combination of performance, versatility and value.
  • XC crankset uses Shimano's Octalink-splined BB interface for reliable power transfer
  • Specialized Fast Trak LK Sport tires use a reduced knob height for lower rolling resistance
  • Avid BB5 mechanical disc brakes with 160mm G2 Clean Sweep rotors for controlled stopping power
  • 80mm smooth-travel fork with preload adjustment and size-specific spring rates for fine-tuned performance
  • Fully butted A1 Premium Aluminum frame with Trail 29-inch geometry for greater control, leverage and bump performance
