Scott's Voltage JR 24 Disc is a rugged ride that offers endless fun. This tough park bike features a Scott aluminum frame that's ready for the aspiring dirt jumper. An SR Suntour suspension fork soaks up landings and stutter bumps. The wheels are built tough with burly Alex rims and grippy tires that keep them rolling from one session to the next. The tough-as-nails 21-speed Shimano drivetrain provides excellent shifting and is built to last. Plus, the powerful Tektro discs offer pinpoint control.
