Delve deeper into the woods and explore new terrain on Diamondback's Response 29. Its nimble 6061-aluminum frame provides an excellent platform for off-road mastery. The big 29-inch wheels and SR Suntour suspension fork smooth out the rough stuff so you ride in control and have more fun on every trail. Plus, this sweet mountain bike boasts a 21-speed Shimano drivetrain for crisp shifting and easy climbing. You'll also love the powerful Tektro disc brakes that offer excellent stopping power and the aggressive WTB tires that grip great.
