Features

  • X-Fusion Velvet Fork

    The X-Fusion Velvet fork and 02 PRO R rear shock are custom tuned for young shredders light weight, allowing them to get the most out of the 120mm of travel. The air springs can be easily adjusted with a shock pump to match your child's weight and riding style.

  • Shimano 1x10 Drivetrain

    The Shimano Cues 1x10 drivetrain delivers smooth, reliable shifting and the 11-48t cassette offers plenty of range to get up steep climbs. Thanks to the clutch rear derailleur, there is no clunking or rattling from the drivetrain and less dropped chains!

  • Hydraulic Disc Brakes

    Tektro hydraulic brakes provide tonnes of power and all weather performance. Levers specifically designed for small hands are easy to reach and will save any rider in a sticky situation.

  • Dropper Post

    The Tranz dropper post allows for quick and easy saddle height adjustment on the fly, improving your child's control and confidence on descents and technical sections.

  • Wheels & Tyres

    Entity X15 Disc wheels are lightweight and durable, and come pre-taped for easy tubeless setup. The stock Vee Tyres off loads of grip and puncture protection! For a full tubeless setup, you will need valves, sealant and tubeless ready tyres.
