Maybe you're finding your legs on the singletrack, or perhaps you're just dirt-curious? Either way, the Rockhopper Sport 29 is the only bike you need to live out your trail fantasies. It places a focus on long haul performance, and we're not talking about 100-mile trail rides. Its corrosion-resistant hardware is built to last, while all of the components are purposely selected for their balance of strength and capability. And setting everything over the top is our Trail 29 Geometry that's guaranteed to leave you feeling planted, confident, and efficient out there on the dirt.
  • The frame is constructed from A1 Premium aluminum in order to provide a lightweight, durable platform to support our acclaimed Trail 29 Geometry. Combined, you get a bike that's efficient on climbs and eager on descents.
  • Custom SR Suntour XCM 29 fork pairs a coil spring with our Multi-Circuit Damping technology to eliminate any "pogo" effect by delivering 80/100mm (size-specific) of hydraulic damped suspension and rebound that smooths out rough terrain.
  • With reliable traction, puncture-resistance, and sheer speed over the dirt, our 29x2.1" Ground Control Sport tires will keep you rolling with confidence over almost any terrain.
  • 29" alloy Stout rims have been laced to our Stout hubs to form wheels that allow you mow over everything in sight, climb gracefully, and get to the bottom of the trail eager for more.
