Trek Fuel MX 9.8 XT Chameleon Green: one mountain bike to do it all

OCLV Mountain carbon frame, Fox Factory suspension with 150 mm at the rear and 160 mm up front, Shimano XT M8200 1x12 drivetrain with 10-51: the Trek Fuel MX 9.8 XT Gen 7 covers a very wide range of riding. Weight not published by Trek for this version; Trek gives 15.28 kg for the Fuel EX 9.8 XT and 15.97 kg for the Fuel LX 9.8 XT Di2 in a size M, two good points of comparison. Its Gloss Chameleon Green/Matte Black finish pairs a glossy, colour-shifting chameleon green with a matte black.

Who is it for?

For riders who will only have one mountain bike in the garage and want to do everything with it: Wednesday evening rides, weekend trail rides, a few enduro descents and a trip to the mountains. They ride often and appreciate parts that are easy to find and replace.

The LVR workshop view

OCLV Mountain carbon, Trek's signature. Since 1992, Trek has been eliminating micro-voids from its frames by compacting the fibres under heat and pressure: this is the OCLV process. Its Mountain version, used on the Fuel MX 9.8 XT, prioritises impact resistance, essential on a bike that spends its rides in scree. The frame integrates storage, a threaded BSA bottom bracket and ISCG 05 mounts for a chain guide, under Trek's lifetime warranty.

	OCLV Mountain (Fuel MX 9.8 / 9.9)	Alpha NEXT Platinum (Fuel MX 9)	Carbon Fuel EX / LX
Level	Trek's mountain bike carbon, tuned for impacts	Trek's most advanced aluminium	Same Gen 7 Fuel platform
Construction	Plies compacted under heat and pressure	Alpha NEXT Platinum alloy	Identical OCLV Mountain carbon
Gen 7 Fuel frameset (M)	3.31 kg (Fuel EX figure)	4.95 kg (Fuel EX figure)	3.31 kg for the EX
What it means	Around 1.6 kg less on the frame, lifetime warranty	Heavier, gentler on the budget	145 / 150 mm (EX) or 160 / 170 mm (LX)

Put simply: here, carbon is not about climbing faster by a few grams, it lightens the frame by around 1.6 kg compared with Fuel aluminium, making the bike easier to handle and carry. The 9.8 XT pairs this frame with Fox Factory suspension and a proven cable-actuated Shimano groupset.

A mountain bike ridden several times a week wears out its drivetrain: on the 9.8 XT, the Shimano cassette, chain and pads are common parts, replaceable without any exotic references. The frame also accepts a chain guide thanks to its ISCG 05 mounts, useful if you lean more towards descending.

The integrated frame storage lets you head out without a backpack on short rides: spare tube, tyre lever and small tool all fit inside. For long days, the universal UDH hanger makes repairs easier, since most bike shops stock it in case of breakage.

Which Fuel should you choose?

Model	Frame	Travel rear / front	Drivetrain	Weight (M)
Fuel EX 9.8 XT	OCLV Mountain carbon	145 / 150 mm	Shimano XT 1x12	15.28 kg
Fuel MX 9.8 Eagle 90	OCLV Mountain carbon	150 / 170 mm	SRAM Eagle 90 T-Type 1x12	not disclosed
Fuel MX 9.8 XT	OCLV Mountain carbon	150 / 160 mm	Shimano XT 1x12	not published
Fuel MX 9.8 XT Di2	OCLV Mountain carbon	150 / 160 mm	Wireless Shimano XT Di2	not disclosed

Our take: versatile, the 9.8 XT sits at the centre of the carbon Fuel MX range: 10 mm less up front than the Eagle 90, the same suspension as the XT Di2. Compared with the Fuel EX 9.8 XT (15.28 kg in M), it brings a little more travel, 150/160 versus 145/150 mm.

LVR sizing advice

If you are unsure, go for the smaller size for agility on technical trails, the larger for stability on fast descents. The Line Dropper goes from 150 mm (S) to 170 mm (M) then 200 mm.

Size	S	M	L	XL	XXL
Rider height (cm)	155-165	165-177	177-188	188-195	195-203
Inseam (cm)	74-78	79-83	84-89	89-91	91-97
Dropper post (mm)	150	170	200	200	200
