The 2023 Trek Fuel EX 9.9 combines a light and nimble carbon frame with Shimano's best drivetrain and top-shelf suspension for a ride that's ready to rally wherever you point it. It's dripping with high-end upgrades like buttery-smooth Kashima coat, quick-engaging carbon wheels, a super-slick one-piece bar and stem, and handy multi-tool hidden in the steerer tube.

A light and stiff OCLV Mountain Carbon frame with a 150 mm FOX Factory 36 fork with EVOL air spring and GRIP2 damper and FOX Factory Float rear shock with 2-position damper that makes light work of the gnarliest rock gardens on the mountain. Carbon wheels that keep weight down while offering stiff and reliable tracking through rowdy terrain, and Shimano's finest drivetrain with the lightweight, reliable and precise XTR component package. Plus, you'll get adjustable geometry for fine-tuning your ride and in-frame storage that lets you keep your set-up tidy without leaving behind trail essentials.

The Fuel EX 9.9 is a top-tier trail bike that's built for riders with an affinity for the finer things in life. It's a complete package, with the industry's best components from the ground up, with Shimano's XTR drivetrain, FOX Factory fork, carbon wheels and frame, and geometry that's ready to be tuned for how you ride.

- You can tackle any trail on the mountain with its progressive geometry that makes light work of steep, punchy climbs and turns around to rally the descents

- Its cream of the crop component package has you fully equipped with the finest shifting group set from Shimano, and buttery-smooth suspension from Fox

- 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

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.
