Love big forests, balcony trails and singletrack that snakes between the trees? This Fuel offers you comfort and precision, especially if you would rather explore than race the clock.
Alpha aluminium, Trek's expertise. Alpha is the generic name for Trek's alloys; the NEXT Platinum version, introduced with the Gen 7 Fuel, is the most advanced. This Fuel EX 9 XT benefits from a frame that does more than just be strong: you can change its progression, flip suspension parts to adjust the geometry, slip a repair kit into the down tube and fit a chain guide on the ISCG 05 mounts.
| Alpha Silver | Alpha NEXT Platinum | OCLV Mountain | |
| Level | Trek's entry-level alloy | The most refined of the Alpha alloys | Trek's mountain bike carbon |
| Construction | Alpha aluminium, hardtail frame | Alpha aluminium, adjustable Fuel platform | OCLV process tuned for impacts |
| Reference bike | Marlin 4 to 7 | Fuel EX 5, 8 and 9 | Fuel EX 9.8 and 9.9 |
| What it means | Simple and affordable, no rear suspension | 4.95 kg frameset in M, tough and more affordable | 3.31 kg frameset in M, 1.64 kg less |
In short: with identical Fox Factory suspension and XT drivetrain, the carbon Fuel EX 9.8 XT weighs 15.28 kg in M, 1.86 kg less than this aluminium version. The extra weight is felt on long climbs, much less once the slope tips downhill.
In the forests of the Espinouse, trails alternate between flowing sections, roots and mossy stones: the Fox Factory 36 GRIP X2 filters out small bumps while staying firm as the slope steepens. The Float X Factory keeps good traction when accelerating over roots.
The XT brakes with a 203 mm front rotor stay easy to modulate on damp ground, and the XT drivetrain copes well with mud and leaves. We recommend checking the pivot bearings after a wet season.
| Model | Frame | Fork / rear | Drivetrain | Weight (M) |
| Fuel EX 8 | Alpha NEXT Platinum alloy | Fox Rhythm 36, 150 / 145 mm | SRAM Eagle 70 1x12 | 16.58 kg |
| Fuel EX 9 Eagle 90 | Alpha NEXT Platinum alloy | RockShox Lyrik Ultimate, 150 / 145 mm | SRAM Eagle 90 1x12 | 16.58 kg |
| Fuel EX 9 XT | Alpha NEXT Platinum alloy | Fox Factory 36, 150 / 145 mm | Shimano XT 1x12 | 17.14 kg |
| Fuel EX 9.8 XT | OCLV Mountain carbon | Fox Factory 36, 150 / 145 mm | Shimano XT 1x12 | 15.28 kg |
Our take: the carbon 9.8 XT version, with the same Fox Factory suspension and groupset, is 1.86 kg lighter. In between, the aluminium XT Di2 version comes in at 16.88 kg.

LVR sizing advice To choose between two sizes, think about your terrain: the more compact for twisty singletrack, the longer for fast, open descents. The dropper post grows with the frame, up to 200 mm in L and XL; the S switches to 27.5 inches at the rear.
