Who is it for?

For the experienced mountain biker who rides a lot, knows their set-up preferences and wants the best original equipment, without having to change wheels, cockpit or seatpost in the months after purchase.

The LVR workshop view

OCLV Mountain carbon, Trek's signature. At the top of the Fuel MX range, the 9.9 X0 AXS keeps the OCLV Mountain carbon frame of the 9.8: a mountain bike carbon compacted under heat and pressure, with fibres laid out to withstand repeated impacts rather than break lightness records. What sets it apart is the kit fitted around it: carbon wheels, carbon handlebar and wireless electronics. Trek lifetime warranty on the frame.

	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: on a 9.9, it is no longer the frame that makes the difference but the parts that complete it. The Line Pro 30 carbon wheels and the Race Face ERA cockpit reduce rotating mass and weight up front, which you feel above all when changing direction and accelerating.

The Line Pro 30 carbon wheels reduce rotating mass, which you feel at every acceleration out of corners and over successive bumps. The 800 mm Race Face ERA carbon handlebar dampens some of the scree vibrations before they reach your wrists, delaying forearm fatigue.

The Fox Transfer Neo dropper post is operated without a cable, like the SRAM X0 AXS derailleur: the cockpit keeps only the brake hoses and becomes very clean. We configure these electronic components and update their firmware at handover.

Which Fuel should you choose?

Model	Frame	Travel rear / front	Drivetrain	Weight (M)
Fuel EX 9.9 X0 AXS	OCLV Mountain carbon	145 / 150 mm	Wireless SRAM X0 AXS	14.08 kg
Fuel MX 9.8 XT Di2	OCLV Mountain carbon	150 / 160 mm	Wireless Shimano XT Di2	not disclosed
Fuel MX 9.9 X0 AXS	OCLV Mountain carbon	150 / 170 mm	Wireless SRAM X0 AXS	not published
Fuel LX 9.8 XT Di2	OCLV Mountain carbon	160 / 170 mm	Wireless Shimano XT Di2	15.97 kg

Our take: the Fuel EX 9.9 X0 AXS, claimed at 14.08 kg in M, makes do with 145/150 mm; this MX adds 5 mm at the rear and 20 mm up front. Compared with the MX 9.8 XT Di2, it brings the 170 mm fork and carbon wheels.

LVR sizing advice

Between two sizes, choose the smaller one for playful handling, the larger one for stability on long descents. The Fox Transfer Neo goes from 150 mm in S to 175 mm in M and 200 mm above.

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	175	200	200	200

Your questions

Are carbon wheels fragile?	They are designed for mountain biking; a properly inflated tubeless set-up limits the risks from impacts.
How is the seatpost operated?	Without a cable: the Fox Transfer Neo is electronic, like the X0 AXS derailleur.
Which batteries need charging?	The AXS derailleur one, supplied with its charger, and the dropper post one.
Is the marbling unique?	The light green veins vary slightly from one frame to another.
