For the rider who links run after run at the region's enduro spots, around Lodève or Lake Salagou, and wants to climb back up the tracks rather than take a shuttle. It suits the mountain biker who wants to adjust the geometry to the terrain of the day.
OCLV carbon, Trek's signature. OCLV is Trek's in-house method: carbon layers pressed at high temperature to produce a dense laminate with no micro-voids. The Mountain version, reserved for mountain bikes, prioritises impact resistance over gram-shaving, a logical choice when the motor and battery add weight. This Fuel+ LX uses exactly the same frame as the Fox-equipped version, with adjustable head angle and progression, under the Trek lifetime warranty.
| OCLV Mountain (Fuel+ 9.7 to 9.9) | Alpha NEXT Platinum (Fuel+ EX 8) | Road OCLV (Madone, Domane) | |
| Level | Mountain bike version of OCLV carbon | The pinnacle of Alpha aluminium | OCLV 500 to 900 on the road |
| Construction | Hot compaction, reinforced impact zones | Hydroforming, variable wall thicknesses | Hot compaction, weight is the priority |
| Reference bike | Fuel+ EX 9.8 XT: 20.10 kg (M) | Fuel+ EX 8: 21.08 kg (M) | not applicable |
| What it means | Lighter frame, lifetime warranty | Cheaper, 0.98 kg heavier | Road use only |
Put simply: this version replaces the Fox 38 and DHX2 shock with a RockShox ZEB Ultimate fork and Vivid Ultimate shock, without changing the 160 / 170 mm travel. Trek does not publish its weight; the Fox version, with the same frame and motor, serves as the benchmark at 20.88 kg in M.
The adjustable head angle changes the bike's character: slacker, it gains stability on steep slopes and landings; steeper, it becomes lively again on twisting singletrack. We make this adjustment in the workshop and tell you which position suits your routes.
On the red earth of Lake Salagou, dusty in summer and slippery after rain, the Assegai MaxxGrip up front keeps consistent grip in the turns. The TQ motor stays within the legal framework for e-bikes, 250 W nominal and assist cutting out at 25 km/h, but it is enough to link the climbs between descents.
| Model | Motor / battery | Rear / front travel | Drivetrain | Weight (M) |
| Fuel+ MX 9.8 XT Di2 | TQ HPR60 / 580 Wh | 150 / 160 mm | Shimano XT Di2 | 19.79 kg |
| Fuel+ LX 9.8 Eagle 90 (Fox) | TQ HPR60 / 580 Wh | 160 / 170 mm | SRAM Eagle 90 | 20.88 kg |
| Fuel+ LX 9.8 Eagle 90 (RockShox) | TQ HPR60 / 580 Wh | 160 / 170 mm | SRAM Eagle 90 | not disclosed |
| Fuel+ LX 9.8 XT | TQ HPR60 / 580 Wh | 160 / 170 mm | Shimano XT | not disclosed |
Our take: for bike parks, this Fuel+ LX keeps its 29-inch wheels while the Slash+ 9.9 adopts a mixed 29 / 27.5 setup for 21.83 kg in M. Compared with the Fuel+ MX 9.8 XT Di2 (19.79 kg), the LX adds 10 mm of travel at each end.

LVR sizing advice Torn between two sizes? Take the smaller one if you like jumping and tight, technical riding, the larger one if stability at high speed is your priority. From S to XXL, the Line Dropper goes from 150 to 200 mm of travel.
