Trek Fuel+ LX 9.9 X0 AXS Lichen Green: choosing between Fuel+ LX and Slash+

29-inch wheels at both ends, a 170 mm RockShox ZEB Ultimate fork and a Vivid Ultimate shock for 160 mm at the rear: the Trek Fuel+ LX 9.9 X0 AXS is the high-end TQ enduro bike that sticks with big wheels. It gets a TQ HPR60, a 580 Wh battery and the most complete equipment in the family. As for its weight, Trek specifies: not published for this version; benchmark, Fuel+ LX 9.8 Eagle 90 at 20.88 kg in size M. The Lichen Green/Keswick Green Splatter splashes intense green over a soft lichen green.

Who is it for?

For the rider torn between two TQ enduro e-MTBs who prefers the rollover of a 29-inch rear wheel, which handles holes better and carries momentum. It is aimed at those who alternate big mountain days with committed descents.

The LVR workshop view

OCLV carbon, Trek's signature. OCLV carbon is born from a hot compaction process that eliminates voids between the fibres: the sounder the laminate, the less material is needed for a given stiffness. The OCLV Mountain variant applies this principle to durability against the impacts typical of mountain biking. On the Fuel+ LX 9.9, this frame gets the most refined parts in the family, a wireless drivetrain, Maven Silver brakes and a carbon-railed saddle, and carries a Trek lifetime warranty.

	OCLV Mountain (Fuel+ 9.7 to 9.9)	Alpha NEXT Platinum (Fuel+ EX 8)	Road OCLV (Madone, Domane)
Level	Trek mountain bike carbon	Alpha aluminium, alloy range	Trek road carbon
Construction	Dense laminate, impact resistance	Tube shaping by fluid pressure	Dense laminate, lightness
Reference bike	Fuel+ EX 9.8 XT: 20.10 kg (M)	Fuel+ EX 8: 21.08 kg (M)	not applicable
What it means	The lightest platform in the range	0.98 kg heavier in EX	Irrelevant for enduro

Put simply: the 9.9 X0 AXS is the best-equipped Fuel+ LX: Line Pro 30 wheels, Maven Silver brakes, SRAM wireless drivetrain, Fox Transfer Neo dropper and carbon handlebar, built around RockShox Ultimate suspension. Trek does not give its weight; the 9.8 Eagle 90, with an identical frame and motor, serves as the benchmark at 20.88 kg in M.

A 29-inch rear wheel rolls over steps and holes more easily, and holds its speed on rough tracks. The Slash+ 9.9 makes the other choice, a 27.5-inch wheel at the back for more clearance and liveliness; on the long loops of the Montagne Noire, the big wheels of the Fuel+ LX make progress smoother.

The ZEB Ultimate and its ButterCups filter out fine vibrations, while the Charger 3.2 RC2 damper deals with the big hits. The TQ, limited like any European e-bike to 250 W nominal with assist that stops at 25 km/h, helps you climb without turning the bike into a heavy machine.

Which Fuel+ should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Fuel+ LX 9.8 Eagle 90 (RockShox)	TQ HPR60 / 580 Wh	160 / 170 mm	SRAM Eagle 90	not disclosed
Fuel+ LX 9.8 XT Di2	TQ HPR60 / 580 Wh	160 / 170 mm	Shimano XT Di2	not disclosed
Fuel+ LX 9.9 X0 AXS	TQ HPR60 / 580 Wh	160 / 170 mm	SRAM X0 AXS	not disclosed
Slash+ 9.9 (mixed 29 / 27.5)	TQ HPR60 / 580 Wh	170 mm fork	SRAM X0 AXS	21.83 kg

Our take: compared with the Slash+ 9.9 (21.83 kg in M, mixed 29 / 27.5, 170 mm up front), the Fuel+ LX 9.9 X0 AXS keeps 29-inch wheels and 160 / 170 mm. The benchmark weight for the Fuel+ LX family is 20.88 kg in M for the 9.8 Eagle 90.

LVR sizing advice

Between two sizes, choose the more compact one for a lively bike on twisting trails and the longer one for speed on descents. The Fox Transfer Neo offers 150 mm in S, 175 mm in M and 200 mm from L upwards.
