Rockhopper Expert 2X

2020 Rockhopper Expert 2X

When you’re ready to take your riding to the next level, the Rockhopper Expert 2X is the perfect riding partner for those new adventures. We outfitted our light, strong A1 SL Aluminum frame with the best parts in its class to create the ideal companion for any trail.

AIR-SPRUNG AWESOMENESS

The air spring in the SR SunTour XCR-Air 29 suspension fork not only keeps things light up front, it offers the ideal balance of responsiveness and efficiency, soaking up big hits and ironing out small bumps. The adjustable rebound lets you further tune the ride.

GET ALL THE GEARS

With a 20-speed Shimano Deore drivetrain, there’s pretty much nowhere you can’t go. The Shadow Plus™ rear derailleur tucks out of the way of roots and rocks, while Rapidfire Plus™ shifters offer fast, precise gear changes without shifting your grip on the bars.

Powerful, easy-to-control Shimano hydraulic disc brakes offer reliable stops no matter the conditions.

Ground Control Sport front and Fast Trak rear tires provide optimal traction on all terrain.

Stout XC handlebars offer the perfect ergonomic contact points for optimal comfort and control.
