Who is it for?
For the mountain biker who wants a reliable bike, easy to maintain and able to swallow every descent in the region, without worrying about batteries or electronics. It suits the regular rider who goes out every week. This version is available in M and L.
The LVR workshop view
Why an aluminium Fuel MX? The frame is built from Alpha NEXT Platinum, the top tier of Trek's alloys, ahead of Alpha Platinum and Alpha Silver. On the Gen 7 Fuel platform, the aluminium frame kit (4.95 kg in M, measured on the Fuel EX) weighs 1.64 kg more than the carbon kit (3.31 kg): that is the price of toughness and a controlled budget.
| Alpha NEXT Platinum (Fuel 9) | OCLV Mountain (Fuel 9.8 / 9.9) | Alpha Platinum (Slash 8) | |
| Level | Trek's best aluminium | Trek's mountain bike carbon | High-end alloy, one step below NEXT |
| Designed to | Take knocks at a sensible cost | Save weight, resist impacts | Aluminium enduro frames |
| Gen 7 Fuel EX frameset (M) | 4.95 kg | 3.31 kg | not applicable |
| What it means | Heavier, but unbothered by small knocks | 1.64 kg less on the frameset | Previous aluminium generation |
In short: you gain a frame that forgives knocks and crashes, and you lose a few hundred grams on the climbs. For a bike that is ridden every week, it is a sensible compromise.
The Shimano XT drivetrain is a benchmark for toughness: parts are easy to find, adjustments are simple and the whole thing lasts several seasons of intensive use. With a 10-51 cassette and a 30-tooth chainring, the gear range covers steep climbs as well as accelerations.
The four-piston XT M8220 brakes, with a 203 mm rotor at the front, offer power and endurance that are invaluable on long descents. Bleeding them is simple; we recommend doing it once a season to keep a consistent lever feel.
Which Fuel should you choose?
| Model | Frame | Travel rear / front | Drivetrain | Weight (M) |
| Fuel EX 9 XT | Alpha NEXT Platinum alloy | 145 / 150 mm | Shimano XT 1x12 | 17.14 kg |
| Fuel MX 9 XT | Alpha NEXT Platinum alloy | 150 / 160 mm | Shimano XT 1x12 | 16.91 kg |
| Fuel MX 9 XT Di2 | Alpha NEXT Platinum alloy | 150 / 160 mm | Shimano XT Di2 1x12 | not disclosed |
| Fuel LX 9 XT | Alpha NEXT Platinum alloy | 160 / 170 mm | Shimano XT 1x12 | 17.79 kg |
Our take: at 16.91 kg, the MX 9 XT weighs 230 g less than the Fuel EX 9 XT (17.14 kg) and has more travel. The Fuel LX 9 XT, at 17.79 kg and 160/170 mm, is aimed squarely at enduro.

LVR sizing advice If you are between two sizes, the smaller favours handling in switchbacks and slow sections, the larger brings stability as speed rises. Dropper post travel follows frame size.

Your questions
| Shimano or SRAM? | A matter of preference; XT is renowned for its feel and ease of maintenance. |
| Is a 203 mm rotor useful? | Yes, it dissipates heat better on long descents. |
| Which sizes are available? | This version is available in M and L; we confirm the size with you. |
| Does the grey show the dirt? | No, the black flecks hide everyday marks well. |
|
The LVR Cycles verdict A solid, predictable Fuel MX, equipped with a proven Shimano XT drivetrain and brakes. Its grey flecked with black goes with any kit.
