Hardrock Sport
Technical Specifications
AN OLD FAVORITE MADE NEW, the Hardrock is still the most versatile hardtail for kicking around town, but its lighter weight, more efficient alloy chassis and category-leading specifications make it the perfect introduction to XC Trail riding.
  • This fully butted A1 Premium Aluminum frame offers improved fatigue life and comfort in a high performance and lightweight chassis, with an ORE top/down tube, externally relieved headtube and reinforced disc-brake mount.
  • An SR Suntour suspension fork lends 80mm of travel, with external preload adjustment for quick fine-tuning and a mechanical lockout for minimizing power-robbing movement.
  • The Specialized 3D-forged alloy stem offers a 10-degree rise for perfect bar positioning.
  • A Sram X4 rear derailleur and X4 8-speed trigger shifters allow sure, precise and quick shifts with the flick of a finger.
  • The crankset utilizes Shimano’s Octalink splined bottom-bracket interface for maximum power transfer.
  • Specialized Fast Trak LK Sport tires have a low knob height for efficiency and shoulder knobs for precise cornering.
  • The Specialized XC saddle features abrasion-resistant side patches for enhanced durability.
