GT Stomper Ace 26 Inch Mountain Bike Green

Brand:GT

Code:C:1GT54101U20

Built with the same attention to detail as our adult bikes – the Stomper Ace 26” has a lightweight aluminium frame with geometry perfected for younger rippers wanting to hit the singletrack. Suntour suspension forks, Shimano gearing, disc brakes and Kenda tires means this bike is built right, and rides right.

Features:

  • Improved Geometry bikes with the LegitFit system feature geometry adjustments to improve ergonomics for youth statures. The result: Increased stability, comfort and confidence for a wider range of riders.
  • Easier Pedaling bikes with the LegitFit system have their pedal positions moved slightly forward. The result: Makes it easier to pedal.
  • Better Positioning bikes with the LegitFit system have narrower crank and pedal positions that match the width of a child’s hips. The result: A stronger, more natural pedal stroke.
