Excuse the brag, but we’ve really outdone ourselves here. Proving that true trail-taming capability doesn’t have to come at an intimidating price—the Rockhopper Expert is the culmination of 30 years of redefining the relationship between value and performance.
Start with a painstakingly engineered Premium A1 Aluminum frame, add in modern geometry that keeps one eye on efficiency and the other on confident capability, and you have the rock-solid foundation of our best Rockhopper yet.
Pair that with a parts list that just doesn’t quit (can we get a shoutout for RockShox’s Judy SoloAir fork and Shimanos’s always-in-charge MT-200 hydraulic disc brakes?), and you have a tubeless-ready, SRAM NX 1x12-equipped Rockhopper that’s absolutely prepared to fly.
