Reviews Description: What is a Recoil? The dictionary defines recoil as "to spring or come back; react." The Diamondback Recoil takes that definition to heart. Whether it is flying down the wide open trail or making its way through twisty single track, the Recoil will react to what is under its tires and then spring back and be ready to take on what comes next. With an aluminum 4" travel frame, Tuff Shock Coil rear shock, SR Suntour XCT fork and 24 gears to choose from this bike will not cower in fear. Instead it will spring into action and give you a great ride.
