The Fuel EX 9.8 XT is an all-around trail bike that blends the light, smooth ride of a carbon frame with upgraded parts made for hard rides. Decked out with 150 mm of front and 140 mm rear FOX Performance suspension, you'll be ready to float through the tough stuff, while carbon wheels keep you tracking through rowdy terrain. A Shimano XT drivetrain tops things off for precise shifting for power on descents and relief on long climbs.

You're chasing long flowy and technical descents, and want to pedal back to the top for more, lap after lap. You want the vibration-damping benefits of a carbon frame and carbon wheels, plus upgraded suspension that smooths out the rough and rowdy.

A light and stiff carbon frame with a full FOX Performance suspension package that smooths out rowdy rock gardens and root latices. Plus, carbon wheels that keep your set-up light, while a Shimano XT drivetrain for smooth shifting and brake modulation. Finally, you'll find adjustable geometry and in-frame storage for keeping your set-up dialled just for you.

The Fuel EX 9.8 is the culmination of years of trail riding and progression, with longer front end geometry for tackling steeper and hairier descents, and a steeper seat tube to keep you perched on climbs. It's equipped with the cherry-picked components you want, like upgraded suspension, carbon wheels and a Shimano XT drivetrain.

- You'll get the light weight and vibration-damping benefits of a full carbon frame, and geometry built to handle anything

- It comes with light and stiff carbon wheels that make quick work of technical terrain and keep you on your line, even when things get hairy

- With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations

- We expanded our size range to ensure a better fit for all riders, and use the best-fitting wheels for each frame size: XS frames get 27.5? wheels, S frames get to choose between 27.5? or 29?, and sizes M and up get 29? wheels

- You get the precise shifting and brake modulation of a Shimano XT drivetrain, plus the simple reliability of a threaded bottom bracket

Mountain Bike Buying Guide

Mountain biking is an incredibly diverse sport. Mountain bikes now come in three main flavours. They are XC, Trail and Enduro.

XC – short for cross country, are quick race bikes. They will normally have 29” wheels and come with 100mm of suspension. If you are mainly going to be riding bridleways and natural trails in the South East of England, where our shops are, an XC bike will be the quickest and most efficient option.

Trail – these bikes are designed to be pedalled up and down hill and for use on bridleways and natural trails, but also at dedicated trail centres. They normally come with 130mm or 140mm of suspension travel and can have either 27.5” or 29” wheels, but 29” is quickly becoming the norm. Trail bikes are good all-rounders. They won’t be as fast as an XC bike on the flat but they can handle a lot more challenging terrain, and a few jumps. If you plan on taking your bike to trail centres in Wales, or to the Alps, then a trail bike may be your best option.

Enduro – enduro racing is a thing in and of itself but many people buy enduro bikes for ‘aggressive’ trail riding and uplift days at places like Bike Park Wales. This generally means challenging downhill trails with some big jumps. With around 160mm of suspension travel enduro bikes can take some big hits. They are designed to be efficient enough to pedal up hills but really come into their own when pointed downhill. You get enduro bikes in either 27.5” or 29” wheel sizes as well as mullet setups of 29 at the front and 27.5 at the back.


Men’s and women’s mountain bikes

Nearly all the mountain bikes we sell are now unisex. All of the big brands have gradually stopped doing dedicated men’s and women’s bikes over the last few years. Instead they are focussed on producing bikes in a bigger range of sizes. So, for instance, the Trek Marlin 5 is a unisex bike that now comes in sizes from XXS to XXL large. This means it will fit riders from 4’ 5” to 6’ 5” and everything in between.
