GT Avalanche Sport 2019 Mountain Bike Black

Season : 2019

Brand : GT

Code : G27429M10

Weight : 0.24KG

The 2019 GT Avalanche Sport is a full-on hardtail mountain bike with 27.5" wheels on the small frame and 29" on the larger sizes offering a perfect fit for anyone.

One of the longest-running GT models. Often called the little brother to the Zaskar the one thing you cannot call the Avalanche is short on features. With a high-end aluminium frame and geometry similar to the Zaskar, you will be able to be out riding hard without busting your wallet.

With WTB tyres and rims that offer low rolling resistance and comfort, you can eat up the miles with ease, even more so with the Avalanches light aluminium frame and 3x9 Shimano drivetrain.


This Bike Is Perfect For

The rider that covers a lot of miles and so needs a mountain bike that is great for cross country riding. The Avalanche is equally good for riding around town with its 29er wheels and low rolling resistance tyres, and with the smaller 27.5" wheels on the small frame, it would make a great bike for teenagers or smaller riders.

GT was founded in 1979 by Gary Turner and is still one of the big names in the cycling industry today. Many of the names in the GT mountain bike range have been around since the beginnings of the sport and older mountain bikers will know names like the Zaskar and Karakoram. GT Bicycles don't just trade off their heritage though, they continue to make cutting-edge bikes with regular updates to their range to reflect the latest trends in technology and the mountain bike scene. GT continues to impress with their trusted Aggressor and Avalanche models that are well suited to the beginner or intermediate rider alike.

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
