Who is it for?
For the demanding rider who feels the difference a carbon bar makes in the hands after a long descent and wants a complete bike without changing a thing. This colourway is only available in M, L and XXL, so it is mainly aimed at riders from 165 to 188 cm and very tall riders.
The LVR workshop view
OCLV carbon, Trek's signature. For its mountain bikes, Trek adapts its OCLV process into a Mountain version: the fibres are oriented and reinforced where an enduro frame takes the hits, under the down tube and around the pivots. The result is a frame that is lighter than aluminium without being more fragile, covered by Trek's lifetime warranty. On the Gen 7 Fuel platform, the frame kit difference reaches 1.64 kg in size M according to Trek (3.31 kg versus 4.95 kg, measured on the Fuel EX).
| OCLV Mountain (Fuel LX 9.8 / 9.9) | Alpha NEXT Platinum (Fuel LX 9) | Alpha Silver (Marlin) | |
| Level | Trek's most advanced mountain bike carbon | Higher-grade MTB aluminium | Entry-level aluminium |
| Construction | OCLV layers reinforced in impact zones | Hydroforming, neat welds | Standard tubes |
| Complete Fuel LX (M) | 15.97 kg (9.8 XT Di2) | 17.79 kg (9 XT) | not applicable |
| What it means | 1.82 kg less to haul uphill | Heavier, more affordable | Hardtail range |
In short: 15.97 kg in size M for a 160 / 170 mm coil-sprung bike is the lowest published weight in the whole Fuel LX family. Compared with the aluminium Fuel LX 9 XT, the 1.82 kg difference comes from the carbon frame but also from the Di2 drivetrain, which is lighter than the cable version.
An 800 mm carbon bar does more than save a few grams: its construction filters out some of the high-frequency vibration that tires your forearms in rock gardens. The 800 mm width provides plenty of steering leverage, and we are happy to cut it down in the workshop if you have narrow shoulders.
The XT Di2 M8250 drivetrain is controlled wirelessly from the bar and its shifting is programmable: you choose the function of each button and the speed of multiple shifts. The frame is the same as on the other Fuel LX 9.8 models, with its progression adjustments and ISCG 05 mounts.
Which Fuel should you choose?
| Model | Frame | Travel rear / front | Drivetrain | Weight (M) |
| Fuel MX 9 XT | Alpha NEXT Platinum alloy | 150 / 160 mm | Mechanical Shimano XT 1x12 | 16.91 kg |
| Fuel LX 9 XT | Alpha NEXT Platinum alloy | 160 / 170 mm | Mechanical Shimano XT 1x12 | 17.79 kg |
| Fuel LX 9.8 XT Di2 | OCLV Mountain carbon | 160 / 170 mm | Shimano XT Di2 1x12 | 15.97 kg |
| Slash 9.8 XT Di2 | OCLV Mountain carbon | 170 / 170 mm | Shimano XT Di2 1x12 | 16.63 kg |
Our take: this 9.8 XT Di2 with carbon bar has the lowest published weight of the Fuel LX range, 15.97 kg in M, 1.82 kg less than the aluminium Fuel LX 9 XT. The Slash 9.8 XT Di2 offers 170 mm at the rear for 16.63 kg.

Your questions
| Can the 800 mm bar be cut down? | Yes, we adjust it to your build during preparation in the workshop. |
| Why only M, L and XXL? | That is Trek's offer for this colourway; the other sizes exist in other colours. |
| Does the Di2 need charging often? | No, battery life covers many rides; we show you how to charge it. |
| How should I care for the purple? | A gentle cleaner and an adhesive protection film on the lower down tube are all it needs. |
|
The LVR Cycles verdict The Fuel LX with the most refined finishing kit, with a carbon bar and saddle that improve comfort on long descents. Its dark purple veined with amethyst gives it a character all its own.
