Technical Specifications
ATB - All Terrain Bike SOLID AS A... From the mean streets to demanding dirt trails, the Hardrock® delivers performance and durability in a package that looks good and is built to be solid as a rock.

Inside Tech Building a hardtail frame that'll last a lifetime and is still light enough to ride isn't easy, but in the 25-plus years that we've been building mountain bikes, we've learned a thing or two. For the Hardrock we use a 100% proprietary, butted A1 alloy tubeset that is light, but still tough because we put the material only where it needs to be. Optimized Radius Engineering top and down tubes add even more brawn and still manage to shave weight.
