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.

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...
Apr 2023 · Drew Rohde
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!

Great downtube storage solution
Adjustable and versatile geometry options

Excellent suspension
Solid feel to the frame
Great geometry
Doesn’t feel as sprightly on climbs as some
Tyres give up corner traction too easily in loose or muddy conditions
Sep 2022
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.

Trek’s alloy Fuel EX trail mountain bike lacks the latest features but is the overall package still a winner?
Tight, precise frame
Sorted all round handling
Very efficient suspension feel
Durable Shimano kit
Excellent sizing options
Heavy frame
No internal storage
Press fit bottom bracket
Top Fuel is more playful
