Diamondback Response Comp Mountain Bike (2011 Model, 26-Inch Wheels)

The Response Comp provides the same good times and rugged reliability of the Response Sport, but with the addition of an upgraded Rock Shox Tora fork, SRAM crank set with sealed cartridge bearing Power Spline bottom bracket, 9 speed SRAM shifters and derailleurs, and reliable Avid mechanical disc brakes.

It may seem shocking to some, but there are still several situations where you're better off on a hardtail than a full-suspension mountain bike, such as when riding to class, dirt jumping, riding on smoother trails, or just cruising around the neighborhood. Enter the Diamondback Response Comp mountain bike, which offers the perfect blend of hardtail performance and rugged utility. The Response Comp--which shares the same good times and reliability of the lower-priced Response Sport--offers several upgrades over its sibling, including an improved Rock Shox Tora fork, an SRAM crankset with sealed cartridge bearings, a Power Spline bottom bracket, nine-speed SRAM shifters and derailleurs, and reliable Avid mechanical disc brakes. It's the perfect multipurpose mountain bike for riders everywhere.

The Response Comp offers an ideal blend of hardtail performance and rugged utility.
