Trek Fuel EX 5: the complete trail frame at entry level

The Gen 6 Trek Fuel EX 5 is an Alpha Platinum aluminium full-suspension trail bike, with 140 mm of rear travel, a 150 mm RockShox Recon fork and a Shimano Deore 1x12 drivetrain, weighing 15.29 kg in size M. It keeps all the qualities of the Fuel EX frame: storage hatch, adjustable geometry and a 170 mm dropper post. Its Matte Dnister Black colour, a deep matt black, stays elegant even when covered in dust.

Who is it for?

For the tall rider discovering full-suspension mountain biking who wants a bike that can evolve, or for someone who regularly rides local trails without aiming to race. It also works very well for family rides or outings with friends, on two- to three-hour trail loops.

The LVR workshop view

Alpha Platinum aluminium, the frame of the big brothers. The Fuel EX 5 does not get a cut-price frame: it uses Alpha Platinum and all the Gen 6 features (Mino Link, adjustable leverage ratio, adjustable head angle headset, down tube hatch). It is the build that changes, simpler, which makes it a very good base to upgrade over time.

	OCLV Mountain	Alpha Platinum (Gen 6)	Alpha NEXT Platinum (Gen 7)
Level	Trek's mountain bike carbon	High-end aluminium	Trek's most refined aluminium
Construction	OCLV layup reinforced against impacts	Hydroformed tubes, smoothed welds	Refined tube shapes
Reference bike	Gen 7 Fuel EX frameset: 3.31 kg (M)	Gen 6 Fuel EX 5 / 8	Gen 7 Fuel EX frameset: 4.95 kg (M)
What it means	About 1.6 kg less on the frameset	Proven, robust base	Alloy version of the new generation

Put simply: the value of this bike lies in its frame. The fork, shock or brakes can be replaced later, as we regularly do in the workshop, without changing bikes.

The 12-speed Shimano Deore with a 10-51 cassette offers a very wide range: you can climb the steep tracks of the Béziers hinterland without putting a foot down, and maintenance stays affordable. It is a groupset we know inside out in the workshop, with wear parts that are easy to find.

The Recon Silver fork and X-Fusion Pro 2 shock cover the essentials, with a handy lockout for the road home. If you progress quickly, the frame happily accepts a higher-end fork: it is the upgrade we recommend most often on this bike.

Which Fuel EX should you choose?

Model	Frame	Travel rear / front	Drivetrain	Weight (M)
Fuel EX 5 (Gen 6)	Alpha Platinum alloy	140 / 150 mm	Shimano Deore 1x12	15.29 kg
Fuel EX 8 GX AXS (Gen 6)	Alpha Platinum alloy	140 / 150 mm	SRAM GX AXS T-Type 1x12	15.88 kg
Fuel EX 8 (Gen 7)	Alpha NEXT Platinum alloy	145 / 150 mm	Shimano 1x12	16.58 kg
Fuel EX 9.9 XTR (Gen 6)	OCLV Mountain carbon	140 / 150 mm	Shimano XTR 1x12	13.98 kg

Our take: the Fuel EX 5 is even slightly lighter than the Fuel EX 8 GX AXS (15.29 kg versus 15.88 kg), thanks to narrower 2.40-inch tyres. The 8, on the other hand, brings a Fox 36 fork, wireless shifting and four-piston brakes.
