The Sigth Youth 650B is based on Norco's Ride Aligned™ design system. This means that the frame is specifically tailored for young riders between 148 cm and around 160 cm tall, who find a standard adult bike too large, while the current 24" kids' bike lacks the geometry and travel potential for their next step. The 140 mm RockShox Deluxe R Select shock at the rear, the 150 mm Pike fork at the front, and the adjustable seat post have all been specially tuned to meet the needs of lighter riders, allowing the young thrill-seekers to really push their limits. The SRAM SX Eagle 12-speed drivetrain offers crisp, reliable gear changes with minimal maintenance, and the 180 mm Shimano MT500 brakes bring the kids to a stop before they get into trouble.
