Hydraulic disc brakes with shorter travel brake levers are tuned with lighter modulation compared to adult brakes. This results in greater control and traction on dirt tracks and trails.

A narrow 125 mm saddle width delivers optimal positioning and fit to help young riders tackle longer rides with greater comfort.
Internal Cable Routing
Derailleur and brake cables are routed internally through integrated ports, saving weight while creating a cleaner look and better performance.
