Rockhopper Comp 1X

2020 Rockhopper Comp 1X

When the trail calls, you gotta answer, which means having the right bike for the ride. That’s the Rockhopper Comp 1X, with a light, strong A1 Alloy frame, a simple, efficient single-chainring drivetrain, and quality suspension that keeps you shredding stronger, longer.

SINGLE-RING SIMPLICITY

We swept aside unnecessary complexity with a simple, reliable MicroSHIFT single-chainring drivetrain. With just a single shifter to control, you can intuitively pick the right gear so you can concentrate on the trail, while the wide gear range lets you tackle the steepest climbs.

LIGHTWEIGHT MEETS DURABLE

The A1 Alloy sport frame on the Rockhopper Comp 1X is built for durability and stability, with a lightweight, rugged aluminum tubeset for a smooth ride and efficient climbing. Internal cable routing offers attractive visuals and makes it easier to keep sparkling clean.

MicroSHIFT Advent 1X9 drivetrain with clutch rear derailleur to limit chain slap and derailments.

SR SunTour XCM suspension fork features size-specific travel for consistent handling.

Shimano MT200 hydraulic disc brakes offer reliable, powerful, easily controlled braking.
