Specialized Rockhopper Expert

The Specialized Rockhopper Expert is the top model in Specialized's affordable line of Rockhopper hardtail mountain bikes designed for riders new to mountain biking. It is available in 2 models; the Rockhopper Expert Disc which has 26" wheels, and as the Rockhopper Expert 29 which has 29" wheels and matching 29" frame geometry.  Both have a fully butted M4 alloy frame for lightweight strength and feature a smooth hydraulic damping RockShox Dart 3 fork with preload adjustment. The crankset uses Octalink-splined BB interface for reliable power transfer and SRAM X5 medium-cage rear derailleur and 9-speed trigger shifters give precise gear shifting. Dual-piston hydraulic disc brakes with 160mm rotors deliver smooth, controlled, powerful stops and the alloy double-walled rims give lightweight durability. The Rockhopper Expert Disc comes in a Silver/Dark Silver finish while the Rockhopper Expert 29 comes in a Black finish.
