The GT Avalanche Expert 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 spec on this bike is excellent quality and amazing value on a  bike in this price range.

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 RockShox Recon RL fork with remote lockout and 100mm to smooth the bumps. You’ll get excellent return for your effort on the Avalanche Expert, with the 11-speed Shimano SLX drivetrain powering you through the wilderness. While you roll on WTB Ranger Comp tyres, which give you just the right mix of traction and speed. It is paired with Shimano disc brakes so that you can stop on a dime, every time.

The GT Avalanche Expert is purpose-engineered for the mountain, made to be high on performance but low on cost. The Avalanche Expert will take you from the paths to the trails seamlessly and then really show off its capabilities on the dirt. The Expert pairs an excellent alloy frame, with the superb RockShox fork and 11-speed Shimano SLX drivetrain. You can’t beat the value of the Avalanche Expert as this bike is sure to be hours of fun out and about.
