Big rides are big fun in the right company, and the Rockhopper Comp 2X is up for any adventure. The 18-speed Shimano drivetrain lets you climb strong deep into the day, and the A1 alloy frameset’s smooth, comfortable ride keeps you feeling fresh and ready for anything.
SUPERIOR SHIFTING
Settle in for any climb with the Shimano Altus 18-speed drivetrain, with two chainrings and a wide-range cassette for the perfect gear on any terrain. Ergonomic Rapidfire Plus™ trigger shifters offer precise gear changes without changing your grip compromising control.
