For This Bike

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

The Trek Fuel EX is the most expensive bike in this group test, yet is still awarded our Best Buy – how is that possible? Read our review to find out what makes this bike so good.
Performs on every kind of trail
Fantastic spec
A great balance of composure and agility
Expensive
Seat tube angle could be steeper

The Fuel EX 8 is an impressively capable, versatile, and well-rounded trail bike that is ready for anything you are. Trek redesigned the Fuel EX models for...
Relatively affordable
Good component spec for the price
Great small bump compliance
Versatile/well-rounded
Frame sizing feels a little small
Can be overwhelmed in super aggressive terrain

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

We've been testing two 2019 130mm travel 29er trail bikes; the GT Sensor Expert and the Trek Fuel EX 9.7. Here we review the Trek Fuel EX.
