Product Description

With an affordable price tag, and a build capable of taking you to new heights in the hills, the GT Avalanche Sport 27.5 mountain bike is purpose-engineered for the mountain.

Built using a high-grade 6061-T6 aluminium, the hardtail MTB frame is a superb foundation on which the Avalanche is built. Designed with a tapered head tube that enhances steering precision, and GT’s trademark Triple Triangle seatstay design which reduces flex and enhances durability, the Avalanche is ready to take on the mountains.

The GT Avalanche Sport is offered with two wheel sizes depending on the size of the frame. Here, the X Small and Small models come with 27.5 inch wheels, while the Medium, Large and X Large models are offered with 29er wheels here.

To smooth out the lumps and bumps in the trail, the GT Avalanche sport comes equipped with an SR Suntour XCT-HLO suspension fork that has 100mm of travel. For added efficiency when climbing, a quick turn of the lever is all it takes to lock out the fork.

Giving you plenty of range for all the highs and lows of the mountain, a mix of Shimano Altus & Alivio 3x9 speed gears has you covered. No doubt you’ll want the bike to live up to its name, too, and when the Avalanche comes down the hill, you’ll have a set of Shimano hydraulic disc brakes to keep you comfortably in control the whole way down.

Engineered for the mountain, without breaking the bank. Enjoy the GT Avalanche Sport 27.5 mountain bike.
