The Rock Blaster hardtail mountain bike with features found on big brother's bike as well as Dad's. Tuned travel front shock absorbs the bumps and the sturdy steel frame keeps the bike tracking straight. Shifting is handled by industry leader Shimano with their seven-speed drivetrain featuring twist shifters. Huge monster truck three-inch knobby tires for ultimate traction. Front and rear linear pull brakes keep speed in check. Supple padded seat is easily adjusted with no tools thanks to a quick-release lever clamp. With the Rock Blaster, the fun doesn't stop when the street ends.
