FOR OVER TWO DECADES the Rockhopper has been the best hardtail for any rider looking for thrills and adventure over a wide variety of terrain. The Rockhopper's M4 alloy frame and premium specs deliver category-leading efficiency, value and dependable handling.

  • Shimano’s Deore 9-speed rear derailleur uses a wide-link parallelogram design for increased rigidity, which means accurate shifting and long life.

  • Shimano’s Deore Rapidfire trigger shifters feature Dual Control for extra-fast shifts from thumb and/or forefinger.

  • Tektro’s Auriga Comp dual-piston hydraulic disc brakes feature smooth lever action and easy-to-control stopping power.

  • The Fast Track Control 29x2.0-inch tires feature a dual compound tread for superior traction and durability, whether you opt to go 2Bliss or not.

  • The Indie XC saddle uses our patented Body Geometry design to protect your soft parts.

  • The Rockhopper Expert Disc 29’s M4 manipulated alloy frame features our 29er-specific geometry for a lower center of gravity and increased stability. A fully butted tubeset adds to its lightweight strength.

  • The Specialized 3D-forged alloy stem is stiff and strong and features an oversized 31.8mm bar-clamp area for precise steering.

  • The front suspension features 32mm Cr-Mo stanchions and a smooth 80mm of coil-sprung travel, rebound and preload adjustments, and lockout.

  • The triple-chainring crankset features Shimano’s splined Octalink BB connection, which gives maximum power transfer and smooth pedaling action.
