For This Bike
Jun 2021 · Peter Walker
The Trek Fuel EX has proven itself as an excellent all-rounder in the past. This year, the American brand enters the race with the € 5,999 Trek Fuel EX 9.8 GX, which combines a high-end frame with a mid-level spec but still features Trek's Thru Shaft shock technology. So does it always have to be top-spec? How big is the difference in performance and how does the Fuel EX 9.8 GX fare against its more expensive peers?
Very comfortable uphill
Intuitive handling
High-quality frame with integrated storage compartment
Tires are very puncture prone and generate little traction
Brakes don't do the bike’s potential justice

The Trek Fuel EX 9.9 is an absolute classic in the trail bike segment. Could it also be the perfect bike for the next bikepacking adventure with its modern geometry and spare parts compartment in the down tube? We put the Fuel EX to the test.
Maximum fun on the descents
Intuitive and good-natured handling
Storage compartment in the down tube for tools or snacks
Too sluggish on easy terrain
Too much bike for long straights
Chain slap

A classic trail bike, with a fun and engaging ride built around a solid frame
A solid feeling frame backed up by a ride quality that encourages you to pop and play around
The long Shimano brake levers kill the feel, while the supple rear suspension shows up the budget fork

Trek recently redesigned their popular Fuel EX mid-travel trail bikes for the 2020 model year. The updated geometry brings this bike in line with modern...
Supple rear suspension
Versatile
Fun on a wide range of terrain
Affordable
Moderately heavy
Short dropper post
Frame sizing runs a little small

The updated Trek Fuel EX now features storage in the downtube, 29er wheels, more travel and a gorgeous frame… oh and it’s rollicking fast too.
Punchy trail bike with great handling.
Low profile tyre tread lacks bite.

Having spent a load of saddle time with the 2020 Trek Fuel EX 9.8 on home soil, we've been getting very familiar with this 130mm travel trail brawler. It hasn't all been smooth sailing though. Read on to see what the Fuel EX does well, what it's struggled with, and what changes we've made to our long term review rig.
Stupendously plush rear suspension
The Fox 36 has really stepped up the EX's appetite for gnar
New geometry brings masses of high-speed stability
Rattling from the downtube trapdoor
Knock Block system works but creates practical annoyances
The 35mm carbon bars are overly stiff
Aug 2019 · Mike Levy
Trek's trail bike gets an all-new frame with tweaked suspension and fresh geometry, but where does sit compared to the competition?
Forgiving, deep feeling suspension
It's a wizard on technical climbs
New geometry increases capabilities
It might be too forgiving for some riders
You'll be using the pedal assist lever often
Trek could have gone further with the geometry
