A capable mountain bike for little rippers. For the up-and-coming trail rider, Diamondback makes the Sync'r 24—a completely capable mountain bike with top-shelf components for your little ripper. The 24-inch wheels and low-slung geometry provide just the right fit and handling for the smaller rider, and the 6061 aluminum alloy construction can take plenty of abuse. With big-bike components like a SRAM SX Eagle 1x12 drivetrain, 80mm Suntour fork, and Shimano hydraulic brakes, this bike gives young riders all they need to get to that next level. This model fits riders 53"-62" tall, aged approximately 8-12 years old.
