Features

  • A Frame That Keeps Up With Their Progression​

    Designed for young riders, the lightweight alloy frame delivers agile handling without compromising durability. As their confidence grows, the frame is also dropper-post compatible, giving them more control for future trail adventures.​

  • Steady handling​

    Comes with tapered headtube design, 640 mm handle bar, and 140mm crankarm for a steady handling.​​

  • Kid-Sized Crank Arms​

    Short crank arms are designed to match young riders, promoting a more natural pedaling motion, improved comfort, and reduced strain on growing knees.​

  • Ride Fast. Ride With Confidence

    ​Just like every Xtrada, the Xtrada 24 is built with cross-country geometry designed for efficient, fast riding. Combined with powerful hydraulic disc brakes, it gives young riders the control and stopping power they need to ride confidently on every trail.​

  • Air Spring Fork With Lockout​

    Designed specifically for young riders, the air spring fork can be tuned to their weight for smoother suspension performance and better comfort on the trail. When the terrain becomes smoother, the hydraulic lockout helps improve pedaling efficiency by reducing unwanted fork movement.​
