On a timed stage, every detail counts: the Trek Fuel MX 9 X0 AXS Gen 7 brings together a wireless SRAM X0 Eagle AXS drivetrain, four-piston Maven Silver brakes and RockShox Ultimate suspension with 150 mm at the rear and 170 mm up front, on an Alpha NEXT Platinum aluminium frame. Its weight is not published by Trek; for reference: 16.91 kg in M for the Fuel MX 9 XT with the identical frame. The Matte Sedona Red/Pennyflake Splatter is a matte ochre red scattered with copper flecks.

For the rider getting into regional enduro races and cup rounds in Occitanie, who wants a reliable bike from the transfer to the final stage. It also suits the mountain biker who rides hard in a group and likes to test themselves on the descents.
Alpha NEXT Platinum: first-rate alloy for a top-end build. The Fuel MX 9 X0 AXS combines Trek's most advanced aluminium, above Alpha Silver and Alpha Platinum, with the plushest spec of the alloy Fuel MX range. Trek has not published the weight of this version; the closest reference remains the Fuel MX 9 XT, which shares the same frame, at 16.91 kg in a size M. To put the material in context, the alloy Gen 7 Fuel EX frameset weighs 4.95 kg in M, the carbon version 3.31 kg.
| 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 |
Put simply: you invest in the components (electronic drivetrain, RockShox Ultimate suspension, Maven Silver brakes) rather than in carbon. For a rider who breaks derailleurs more often than uphill time records, it is a very sensible way to spend the budget.
In racing, reliability comes first: an AXS T-Type derailleur that does not go out of adjustment when it clips a rock means a stage that ends without trouble. Managing shifts under load also lets you accelerate at full power out of corners without losing time.
The ZEB Ultimate and the Vivid handle long, repeated descents without losing their effectiveness. We recommend a seal service before the race season, and a check of the Maven Silver bleed, whose power must stay consistent as the rotors heat up.
| Model | Frame | Travel rear / front | Drivetrain | Weight (M) |
| Fuel MX 9 Eagle 90 (RockShox) | Alpha NEXT Platinum alloy | 150 / 170 mm | SRAM Eagle 90 1x12 | 16.78 kg |
| Fuel MX 9 X0 AXS | Alpha NEXT Platinum alloy | 150 / 170 mm | Wireless SRAM X0 Eagle AXS | not published |
| Fuel MX 9 XT | Alpha NEXT Platinum alloy | 150 / 160 mm | Shimano XT 1x12 | 16.91 kg |
| Fuel LX 9 Eagle 90 | Alpha NEXT Platinum alloy | 160 / 170 mm | SRAM Eagle 90 1x12 | 17.38 kg |
Our take: for racing, the X0 AXS is the best-armed alloy Fuel MX; the Fuel LX 9 Eagle 90 (17.38 kg) offers 10 mm more at the rear but a simpler drivetrain. The RockShox MX 9 Eagle 90 keeps the same suspension with a mechanical Eagle 90.

LVR sizing advice To help you decide: the smaller size if you want a lively bike to jump and place, the larger one if you mostly ride fast on open tracks. The Line Dropper goes from 150 mm in S to 200 mm in L and XL.
