The GT Avalanche Comp is an aluminium frame, hardtail mountain bike that is you gateway to the outdoors. The Avalanche is one of GT’s longest running models, and for good reason.

The 6061 T6 aluminium frame w/ Triple Triangle™ and replaceable derailleur hanger is a stiff and durable frame that utilises high-end geometry.  This lightweight frame combines smoothly with the SR Suntour XCM-DS with 100mm travel and hydraulic lockout. You’ll get excellent return for your effort on the Avalanche Comp, with the 2x9 speed Shimano Alivio drivetrain powering you through the wilderness. While you roll on WTB Transition tyres, which give you just the right mix of traction and speed. This is paired with Shimano disc brakes so that you can stop on a dime, every time.

The GT Avalanche Comp is purpose-engineered for the mountain, made to be high on performance but low on cost. The Avalanche Comp will take you from the paths to the trails seamlessly and then really show off its capabilities on the dirt.


  • Shimano Alivio and Deore Drivetrain, 2x9 / Shimano Disc brakes

  • WTB SX19 Double wall Disc rims / WTB Transition 2.25" tires

  • SR Suntour XCM-DS, Coil Sprung Fork, Hydraulic Lockout
