Aluminium full-suspension mountain bike Trek Fuel EX 8 GX AXS: 140/150 mm, Fox 36, wireless GX AXS, 15.88 kg

Trek Fuel EX 8 GX AXS: wireless shifting on an aluminium trail bike

The Gen 6 Trek Fuel EX 8 GX AXS T-Type is an Alpha Platinum aluminium trail bike, with 140 mm of rear travel, a 150 mm Fox Rhythm 36 fork and the SRAM GX Eagle AXS T-Type wireless drivetrain, weighing 15.88 kg in size M. 2.50-inch XR5 tyres and four-piston brakes complete a package ready for rough trails. Its Matte Keswick paint, a dark matt teal, makes a change from the usual black.

Technical specifications

Who is it for?

For the tall rider who rides technical trails all year round and wants a tough bike, without worrying about knocks to an aluminium frame. It also suits the mountain biker moving from a hardtail to their first full-suspension trail bike who wants a modern drivetrain from the outset.

The LVR workshop view

Alpha Platinum aluminium, strong and well finished. The Gen 6 Fuel EX 8 shares its suspension kinematics, Mino Link, adjustable leverage ratio and storage hatch with the carbon versions; only the material changes. Alpha Platinum is Trek's high-end aluminium: hydroformed tubes and smoothed welds, for a frame that forgives knocks and crashes better than you might think.

Put simply: here you get wireless electronic shifting, rare on an aluminium frame, without paying for carbon. The trade-off shows on the scales: 15.88 kg, which is 1.1 kg more than the carbon 9.9 X0 AXS.

The Fox Rhythm 36 uses the chassis of the famous 36, with a simpler GRIP damper: it offers reassuring stiffness in the rock gardens of the Caroux, with an easy-to-use compression dial. Paired with the Float X shock, it gives the Fuel EX 8 very serious downhill behaviour.

The SRAM CenterLine rotors, 200 mm at the front and 180 mm at the rear, gripped by four-piston DB8 callipers, provide a comfortable margin on a large frame carrying a heavy rider. The 2.50-inch XR5 tyres grip well on dry earth and the loose stones of the garrigue.

Which Fuel EX should you choose?

Our take: 1.1 kg more than the carbon Fuel EX 9.9 X0 AXS, but the same kinematics and the same wireless T-Type. The Gen 7 Fuel EX 8 moves to 145 / 150 mm on a NEXT Platinum frame, at 16.58 kg.
