GT Avalanche Sport is an entry level hardtail mountain bike with 27.5 inch wheel size. 27.5 inch wheels have quickly gained popularity amongst as they offer an optimal balance between the reduced rolling resistance that characterises 29ers and the agility and handling of smaller 26 incher wheels. Larger wheels are able to hit obstacles at a lesser angle than smaller wheel sizes, meaning reduced resistance and loss of momentum as the bike hits the the obstacle and continues along the trail. There is also improved traction and stability as the big wheels allow for more tyre tread in contact with the ground.

Avalanche is one of GT's longest standing mountain bike platforms, jam-packed with features designed for taking on the trails. Avalanche Sport is designed for riders looking for a versatile bike that can do anything around town, or take on some light off-road riding. A lightweight aluminium frame makes the bike easy to ride and durable.

Shimano components offer quality shifting performance and reliability. drivetrain offers high performance shifting, while helping to keep the bike affordable. 3x9 drivetrain offers a wide range of gears to give plenty of options for any terrain.

Suntour 100mm forks can be locked out to improve riding efficiency when suspension is not required. Hydraulic disc brakes offer precise control over braking. Overall, GT Avalanche Sport is a versatile bike for riders seeking a bike that can handle a some fun out on the trails.
