Shuttles, lifts and marked trails: the Trek Fuel LX 9 XT Gen 7 feels at home there with its 170 mm Fox Factory 38 fork and 160 mm DHX2 coil shock. 12-speed Shimano XT and four-piston XT brakes complete a package weighing 17.79 kg in size M.

The LVR workshop view

Alpha NEXT Platinum: aluminium designed for enduro. This third and highest tier of Trek's MTB aluminium is reserved for the Gen 7 Fuels. On this Fuel LX 9 XT, it provides a frame that can be adjusted every which way: progression, rocker, shock mount. The threaded BSA bottom bracket does not creak and is easy to remove in the workshop, the ISCG 05 mounts accept a chain guide, and storage is built into the down tube.

	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

In short: a frame made to last and to be tinkered with, without the fear of cracking carbon on a rock. The 17.79 kg in size M are those of a true descending bike that gets back up the hill under its own steam.

At the bike park, repetition wears out kit. The DHX2 coil shock keeps the same behaviour from the first run to the last, with no variation due to heat. Paired with the Fox 38 fork and its 38 mm stanchions, it provides a stiff, precise platform for landing jumps.

After a day of laps, a check is a must: axle tightness, tyre condition, pad wear. The Maxxis Assegai and Minion DHR II tyres with EXO+ casings hold up well, but a pressure suited to landings remains essential. We advise you on pressure and a possible insert.

Which Fuel should you choose?

Model	Frame	Drivetrain	Travel rear / front	Weight (M)
Fuel MX 9 XT	Alpha NEXT Platinum alloy	Mechanical Shimano XT	150 / 160 mm	16.91 kg
Fuel LX 9 Eagle 90	Alpha NEXT Platinum alloy	Mechanical SRAM Eagle 90	160 / 170 mm	17.38 kg
Fuel LX 9 XT	Alpha NEXT Platinum alloy	Mechanical Shimano XT	160 / 170 mm	17.79 kg
Fuel LX 9.8 XT Di2	OCLV Mountain carbon	Wireless Shimano XT Di2	160 / 170 mm	15.97 kg

Our take: for the bike park, this LX 9 XT and the LX 9 Eagle 90 share the same Fox suspension; the XT weighs 410 g more and offers Shimano brakes. The Fuel MX 9 XT is lighter, but less at ease on big jumps.
