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

Compared to a full-suspension mountain bike, a hardtail is better suited to several situations, such as riding to class, dirt jumping, riding on smoother trails, or just cruising around the neighborhood. Combining the perfect blend of hardtail performance with rugged utility, the Response Sport--which shares the same frame and several of the components of the pricier Response Comp--is equipped with an aluminum all-mountain hardtail Response trail frame with a strongbox top tube, a SR Suntour XCM suspension fork, eight-speed Rapidfire trigger shifters, Kenda Klaw XT tires, and a DB All-Mountain saddle. The Response Sport also offers several upgrades from the base-model Response, including a SR Suntour SCT crank set with replaceable chain rings, Tektro Novela 6-inch disc brakes, and Weinmann doublewall rims.

Shimano front and rear derailleurs and 8-speed Rapidfire shifters ensure a smooth ride.
