Purpose-engineered for the mountain, high on performance but low on cost. Avalanche, a staple of the GT mountain lineup. Often referred to as the little brother to the Zaskar, the Avalanche packs a great offroad punch with truly amazing value for money. With a highend aluminium frame and geometry similar to the Zaskar, you will be able to tear up the trails without busting your wallet.

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 is the perfect platform for the value-conscious rider who isn’t willing to skimp on performance.

Speed, speed and even more speed.
