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.
