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.

  • A1 Premium Aluminum frame, disc only, double butted TT, ORE DT, externally relieved head tube, reinforced disc mount, forged dropouts
  • SR Suntour SF7-XCM-HLO Fork, with 100mm travel, lockout, abd 30mm Hi-Ten stanchions
  • Avid BB5 brakes, mechanical disc, 6" G2 Clean Sweep rotor
  • Shimano FCM-341-8 crankset, Octalink Spline, replaceable rings
  • Specialized/Alex HRD 26 rims, double wall disc w/ eyelets
