Strong Aluminium Frame

The Manitou J Unit Sport fork provides 100 mm of air sprung travel with rebound adjustment. It is designed specifically for young riders, offering lighter spring rates and proper tuning. The 15 x 110 mm axle adds stiffness and control on rough terrain.
CUES Drivetrain And Hydraulic Brakes
The Shimano CUES 9 speed drivetrain delivers smooth shifting with a wide range 11 46T cassette for mixed terrain. The short reach shifter is designed for smaller hands. Shimano MT200 hydraulic disc brakes with 160 mm rotors provide strong and predictable stopping power.
Durable Wheels And Grippy Tyres
Marin double wall rims, forged hubs and 2.4 inch Delium Versatile tyres create a tough and stable wheel setup. The tyres use a light construction for easier rolling and are tubeless compatible for improved grip and puncture protection.
