Product Details

2018 GT Avalanche Sport

GT's Avalanche Sport offers high-end geometry and performance with a wallet-friendly price tag. Its aluminum frame and suspension fork keep you on the straight and narrow while soaking up the bumps dotting your path. When the trail gets hilly, you’ve got a huge range of gears—27 of them to be exact—that’ll take you wherever you want to go with the reliable functionality you expect from Shimano. The Avalanche Sport also comes with Shimano hydraulic disc brakes for relentless stopping power, even on long downhill sections when you need to be able to trust your brakes! GT and All Terra kick in handlebar, stem, grips, and saddle to ensure you’re comfortably in control, making it an easy choice to get out and ride.
