The Fuel EX is still the Fuel EX. It just got a little bit EX-er.
It’s clearly a brilliantly balanced all-rounder.

Push it into a high-speed berm, and it simply doesn’t flinch. At all.

Arguably one of the all-time most popular bike models of any MTB on the planet, the ‘Fuel Ex’ has been at the peak of Trek’s MTB line-up for as long as anyone can remember and it has had no fewer than six major design overhauls during that time. Late last year Trek unveiled their newest reinvention of the ‘do it all trail bike’ which rolls out of the store boasting a ton of rider customisation features, including a choice of […]

The new Gen 6, Fuel EX 9.8 is the burliest, most versatile, and most capable Fuel yet; truly up for whatever you want to ride. Trek completely redesigned...
Highly adjustable
In-frame storage
ABP suspension
Mostly stellar build
A little heavy
SRAM Code R brakes
Bar/stem combo limits adjustability

While the new Trek Fuel EX may have alienated a few riders, it will no doubt be a welcome redesign for a lot more riders!
Fast, confident and ready to rock!
More capable than ever
Great downtube storage solution
Adjustable and versatile geometry options
Med/Large size
Bar/Stem combo
SE5 Tires in the wet
Some may not like the newer, burlier bike’s transition

The downtube storage compartment is on the new bike, and while it seems like Trek has put all the things onto the latest Fuel EX, there's one that they didn't: Knock Block.
Wide range of effective geometry adjustments
Just as much fun on smooth trails as it is on scary trails
Great climber, efficient pedaling
One-piece handlebar might be too stiff for some riders
Paint chips easily

The latest Trek Fuel EX trail bike grows in travel and geometry, but still dominates the climbs.
Capable and adaptable mid-travel trail bike
A lot of adjustability
Great price points, and alloy version
Too many options for adjustability?

New geometry, more travel, and even better suspension improves Trek's mid-weight trail bike.

Trek's top-tier Fuel EX 9.9 XX1 AXS delights on the climbs and tackles downhill terrain with it's slack (and very adjustable) geometry.
