For XC hardtail riders looking to upgrade their trail adventures or maybe even nab their first real deal mountain bike, the Rockhopper® is impossible to beat. A lightweight and responsive M4 chassis, capable MTB components and straight-out-of-the-box performance make this bike feel like a much more expensive ride
  • Trail-inspired, fully butted M4 alloy frame for lightweight strength
  • Crankset uses Octalink-splined BB interface for reliable power transfer
  • Dual-piston hydraulic disc brakes with 160mm rotors deliver smooth, controlled, powerful stops
  • SRAM X5 medium-cage rear derailleur and 9-speed trigger shifters for precise, sure-fire shifting
  • RockShox Dart 3 80/100mm-travel fork features preload adjustment and size-specific spring rates for fine-tuned performance
