Trek Fuel LX 9 X0 AXS Lithium Grey: wireless precision for enduro

The Trek Fuel LX 9 X0 AXS Gen 7 brings together an Alpha NEXT Platinum aluminium frame, 160 mm of rear travel, a 170 mm RockShox ZEB Ultimate fork and the wireless SRAM X0 Eagle AXS drivetrain. Trek does not publish the weight of this version; for reference, the Fuel LX 9 Eagle 90, on the same frame, weighs 17.38 kg in a size M. Its Lithium Grey / Trek Black Splatter shade speckles a lithium grey with black splatter.

Who is it for?

It will appeal to the demanding rider who wants crisp shifts, even when stamping on the pedals out of a corner, without paying the price of a carbon frame. It is also a smart choice for the mountain biker who rides a lot and no longer wants to adjust cables.

The LVR workshop view

Why an alloy frame under a wireless drivetrain? Because on an enduro bike, money is better spent on what touches the terrain: suspension, brakes, derailleur. Alpha NEXT Platinum is Trek's most advanced mountain bike alloy, reserved for the Gen 7 Fuel, and gets the same kinematic adjustments as the carbon frame. Trek's lifetime warranty also covers this frame.

	Alpha NEXT Platinum (Fuel LX 9)	OCLV Mountain (Fuel LX 9.8)	Alpha Platinum (Slash 8)
Level	Trek's best MTB aluminium, reserved for Gen 7 Fuels	Trek's mountain bike carbon	Aluminium from the range above
Construction	Alloy engineered for strength, highly adjustable frame	OCLV layup tuned for impact resistance	Tough alloy, simpler kinematics
Reference bike	Gen 7 alloy Fuel EX frameset: 4.95 kg (M)	Gen 7 carbon Fuel EX frameset: 3.31 kg (M)	Complete Slash 8: 16.68 kg (M)
What it means	Takes knocks, more affordable	About 1.6 kg less on the frameset	170 mm alloy enduro, less adjustable

Put simply: this Fuel LX 9 X0 AXS pairs a frame that is not afraid of rocks with an electronic drivetrain that does not go out of adjustment. Trek does not publish its weight: expect a figure close to the 17.38 kg of the LX 9 Eagle 90.

The X0 Eagle AXS drivetrain works without cables: the shifter on the bar communicates wirelessly with the derailleur, which has its own battery. The result: no cable stretch, no housing clogged with garrigue dust, and an adjustment that stays put. The T-Type derailleur mounts directly on the rear axle, making it tougher against impacts.

The XS-1295 cassette and X0 chain deliver crisp shifts under load, useful when you accelerate over the top of a rise before plunging back down. We carry out the AXS firmware update, pairing and set-up when you collect the bike.

Which Fuel should you choose?

Model	Frame	Drivetrain	Travel rear / front	Weight (M)
Fuel LX 9 Eagle 90	Alpha NEXT Platinum alloy	Mechanical SRAM Eagle 90	160 / 170 mm	17.38 kg
Fuel LX 9 X0 AXS	Alpha NEXT Platinum alloy	Wireless SRAM X0 AXS	160 / 170 mm	n/a (reference 17.38 kg)
Fuel LX 9 XT Di2	Alpha NEXT Platinum alloy	Wireless Shimano XT Di2	160 / 170 mm	n/a
Fuel LX 9.8 XT Di2	OCLV Mountain carbon	Wireless Shimano XT Di2	160 / 170 mm	15.97 kg

Our take: compared with the LX 9 Eagle 90 (17.38 kg in M), this X0 AXS keeps the frame and suspension but gains wireless shifting and Maven Silver brakes. For the same approach with Shimano, look at the LX 9 XT Di2.

LVR sizing advice

The frame comes in S, M, L and XL. For aggressive descending, do not size down too much: length keeps the bike stable on steep slopes.

Size	S	M	L	XL
Rider height (cm)	155-165	165-177	177-188	188-195
Inseam (cm)	74-78	79-83	84-89	89-91
Dropper post (mm)	150	170	200	200
