Product Description

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 Comp 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.

Equipped with an SR Suntour XCM-HLO fork, the GT Avalanche Comp has 100mm of suspension travel to keep the front wheel in contact with the ground. While climbing, a quick flick of the switch locks the fork out, making sure all your effort goes to the wheels, and not into the suspension.

The 3x9 speed gearing comes courtesy of a Shimano Alivio/Acera/Deore mix, ensuring reliable gear changes every time you click the lever. Shimano also take care of the brakes too – a set of hydraulic discs give you ample stopping power that isn’t fazed by dirt or rain.

Fun. Affordable. Tough. The GT Avalanche Comp 27.5 is engineered for the mountain.
