Hardrock Disc
Technical Specifications
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.
  • Mechanical disc brakes with 160mm rotors for easy stopping power
  • Specialized Fast Trak LK Sport tires use a reduced knob height for lower rolling resistance
  • 80mm smooth-travel fork with preload adjustment and size-specific spring rates for fine-tuned performance
  • SRAM 7-speed cassette for increased durability, with X3 trigger shifters for smooth, accurate gear changes
  • Fully butted A1 Premium Aluminum frame with double ORE down tube makes for a lighter weight, more compliant and longer lasting bike
