Trek Fuel EX 9.9 X0 AXS Lava: a carbon trail bike that does not go unnoticed

With its Lava finish, a deep, luminous lava red, the Gen 6 Trek Fuel EX 9.9 X0 AXS T-Type makes its ambitions clear: OCLV Mountain carbon frame, Fox Factory suspension and SRAM Maven Silver brakes, weighing 14.78 kg in size M. The size S version offered here rolls on 27.5-inch wheels, with 140 mm of travel at both ends according to Trek's spec. SRAM X0 AXS wireless shifting and the Reverb AXS post leave the handlebar completely clean.

Who is it for?

For the smaller rider looking for a lively, precise bike on descents, able to keep up with a taller group on technical trails. It will also suit the fast-progressing young mountain biker who wants a high-level bike in their size.

The LVR workshop view

OCLV Mountain carbon, the all-electronic version. This Fuel EX 9.9 pairs the Gen 6 OCLV Mountain carbon frame with SRAM's wireless ecosystem: an X0 AXS T-Type rear derailleur mounted directly on the UDH hanger and a radio-controlled Reverb AXS post. The mountain bike carbon layup is designed to resist rock strikes, and the frame keeps its storage hatch and adjustable head angle headset. Trek lifetime warranty on the frame.

	OCLV Mountain	Alpha Platinum (Gen 6)	Alpha NEXT Platinum (Gen 7)
Level	Trek's mountain bike carbon	High-end aluminium	Trek's most refined aluminium
Construction	OCLV layup reinforced against impacts	Hydroformed tubes, smoothed welds	Refined tube shapes
Reference bike	Gen 7 Fuel EX frameset: 3.31 kg (M)	Gen 6 Fuel EX 5 / 8	Gen 7 Fuel EX frameset: 4.95 kg (M)
What it means	About 1.6 kg less on the frameset	Proven, robust base	Alloy version of the new generation

Put simply: this build is not the lightest (14.78 kg versus 13.98 kg for the XTR version), but it is the most modern: no more derailleur or dropper cables to adjust, and Maven brakes built for long descents.

The Fox Factory 36 GRIP X2 fork has a damper with separate adjustments, from the same family as on top enduro bikes. On a 140 mm trail bike, this lets you keep the fork riding high through steps while making it very supple over roots; we offer a base set-up and then a second appointment after a few rides.

The frame has a storage hatch in the down tube: inner tube, tool and tubeless plugs travel without a backpack. The Mino Link and adjustable head angle headset let you adapt the geometry to the steep trails of the Espinouse or the more flowing loops around the Salagou.

Which Fuel EX should you choose?

Model	Frame	Travel rear / front	Drivetrain	Weight (M)
Fuel EX 8 GX AXS (Gen 6)	Alpha Platinum alloy	140 / 150 mm	SRAM GX AXS T-Type 1x12	15.88 kg
Fuel EX 9.9 X0 AXS (Gen 6)	OCLV Mountain carbon	140 / 140 mm (size S page)	SRAM X0 AXS T-Type 1x12	14.78 kg
Fuel EX 9.9 XTR (Gen 6)	OCLV Mountain carbon	140 / 150 mm	Shimano XTR 1x12	13.98 kg
Fuel EX 9.8 XT (Gen 7)	OCLV Mountain carbon	145 / 150 mm	Shimano XT 1x12	15.28 kg

Our take: with the same carbon frame, the 9.9 XTR drops to 13.98 kg; this 9.9 X0 AXS puts ease of use first with its electronics. The Gen 7 Fuel EX 9.8 XT weighs 15.28 kg, 500 g more.

Your questions

Enough travel for enduro?	For occasional enduro, yes; for racing, look instead at the Slash and its 170 mm.
Suspension set-up?	We set the sag, rebound and compression to your weight in the workshop before the first ride.
Is the Lava red glossy?	It is an intense lava red; gentle cleaning is enough to keep it bright.
Can it be converted to 29-inch?	Trek designed the S frame for 27.5; we advise against changing wheel sizes.

The LVR Cycles verdict

A wireless carbon Fuel EX, high-end and proportioned for smaller riders, with top-level suspension. Its Lava red gives it character without overdoing it.

Pros
+ Highly adjustable Fox Factory GRIP X2
+ Powerful, progressive Maven brakes
+ Vibrant lava red

Cons
- Only available here in size S
- Heavier than the XTR version
