The Avalanche is a GT classic and a hardtail MTB that performs well regardless of how you ride it and what you take it over. The Avalanche 3 comes fitted with Tektro hydraulic disc brakes, Shimano components and Suntour forks.

The Avalanche is ridden by Race Whippets and Weekend Warriors alike and feature great strength and durability with a lightweight frame and great reliability. This means these bikes are equally at home on the singletrack, the sprint for the finish line or a Sunday thrash with your friends.

The Avalanche is ideally suited to the leisure rider who wants to experience the thrills of off-roading either on the local trails or tracks, or who wants a bike with greater versatility (on/off road).

From the all-day ride ability of the Sensor, to the classic aluminium hardtail approach of the Avalanche and Aggressor, there's a trail bike for whatever you ride however you ride it.

Each bike is fully built, tested and tuned by Wiggle's team of qualified bike mechanics to ensure you're bike arrives in perfect condition. To find out which size fits you use the size chart below.

About Hard Tail Mountain Bikes

If you are looking for a mountain bike that can comfortably negotiate bumpy, cross-country, singletracks yet still be quick and nimble on the road, then a hardtail bike is for you. Hard tail mountain bikes have front suspension, weigh less and are more pedal efficient when the terrain is smooth, than full suss bikes. A good number of single track racers still use hardtails for these reasons. At wiggle, we stock a wide variety of hardtail mountain bike brands including Felt, Focus, GT, Kona, Mongoose, Saracen and more. So if you are searching for superb, quality spec hardtail mountain bikes at great value with a legendary service to match, then you've come to the right place.
