The GT Stomper Ace 26 is a youth mountain bike that bridges the gap between kids’ bikes and full-sized adult mountain bikes.

Designed with growing riders, it has a lightweight frame, reliable components and kids geometry.

This helps kids develop skills and enjoy every ride; whether it’s on the street, bike path, or trail.

LegitFit System Designed Just for Kids

GTs LegitFit System is the heart of the Stomper range.

Instead of shrinking down adult frames, LegitFit bikes are built from the ground up with kids proportions in mind. This means:

• Shorter crank arms for more efficient pedalling.
• Narrower Q-factor (the space between pedals) for improved alignment and control.
• Optimised geometry to improve balance, stability, and handling.
• As a result, the Stomper Ace 26 is easier to ride, more comfortable and better for younger riders moving up from 24 bikes or smaller.
• Suspension for Trail-Ready Comfort.

The bike is equipped with an SR Suntour XCT suspension fork, delivering 100mm of travel.

This allows the fork to absorb bumps and vibrations from uneven surfaces.

This gives young riders a smoother, more controlled experience. And especially helpful on gravel paths, dirt trails, or light off-road sections.

Simple and Dependable Gearing

A 1×8-speed Shimano drivetrain keeps gear shifting simple and reduces maintenance. With just one shifter to manage, kids can focus on their ride without the confusion of a front derailleur.

The wide-range cassette provides enough gearing for climbs, descents, and everything between.

All-Condition Braking Power

The mechanical disc brakes offer strong and consistent stopping performance in all weather. Whether it’s dry pavement or muddy trails, these brakes give young riders the control they need to stop safely and confidently.

Lightweight Wheels and Trail-Ready Tyres

With 26-inch wheels, the Stomper Ace 26 is the perfect size for pre-teens.

Kenda Small Block Eight tyres are fast-rolling with enough grip for unsealed surfaces. It makes them ideal for everything from neighbourhood rides to weekend trail sessions.

Comfortable and Durable Touchpoints

GT includes thoughtfully chosen components for comfort and durability, including:

• GT Junior MTB saddle for youth-specific fit.
• Alloy handlebars and stem sized for smaller hands and upper bodies.
• Junior platform pedals with grip for all-weather riding.
