Rockhopper Expert 27.5
Rockhopper Expert 27.5
We deliver! Just say when and how.
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 SRAM’s always-in-charge Level hydraulic disc brakes?) and you have a tubeless-ready, SRAM Eagle 1x12-equipped Rockhopper that’s absolutely prepared to fly.
