GT Avalanche Sport Mountain Bike


Unfortunately we are not able to sell our bikes ready-made on our website. Please visit one of the stores below where our trained mechanics will happily help you find the right bike for you.

Getting your feet wet in the world of mountain biking should be about raging across that first stream on two wheels, not emptying your pockets for the toll. With hydroformed alloy tubing and 27.5” wheels, the GT Avalanche Sport is the perfect platform for the value-conscious rider who isn’t willing to skimp on performance.
