Let's go ahead and forego the sales pitch. After all, you're eager to get out there and start exploring the dirt on a Hardrock Disc. The only question is, what wheel size should you go with? No matter your height or experience level, our Hardrock will fit you perfectly, but if you're more inclined to get a little rowdy or you need a little more standover than a 29er can afford, the Hardrock Disc 650b is the perfect choice for you. And with durable, performance-driven components, powerful disc brakes, a bump absorbing suspension fork, and our nimble, playful Sport Trail 650b Geometry, you'll be left feeling confident and inspired.
  • With reliable traction, puncture-resistance, and sheer speed over the dirt, our 650bx2.0" Ground Control Sport tires will keep you rolling with confidence over almost any terrain.
  • 650b alloy rims have been laced to a pair of our sturdiest 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.
  • The frame is constructed from A1 Premium Aluminum in order to provide a lightweight, durable platform to support our acclaimed Sport Trail 650b Geometry. Combined, you get a bike that's efficient on climbs and eager on descents.
  • SR Suntour M303 fork features a coil spring that delivers 75mm of trail absorbing travel.
