Technical Specifications
Description
With Rx Tune on Rockhopper, the lockout-equipped SR Suntour XCM with custom Multi-Circuit damping brings size-specific travel and spring rates to the show in a performance that’s sure to impress while also ensuring consistent geometry, handling and suspension performance, regardless of frame or wheel size.
Beautifully beastly, Tektro HD-M275 hydraulic disc brakes pack a mean bite but deliver their power with a refined, intuitive feel to make for a package that punches way above its pay grade.
Keep things simple with a durable 1x MicroSHIFT drivetrain that offers plenty of range along with a clutch-equipped rear derailleur that keeps your ride quiet—and your chain on.
Pair dead-reliable hubs from Shimano with our 25-millimeter internal diameter, hookless Stout rims for a wheelset hat-trick: strong, light and durable.
