Who is it for?

For the trail rider who spends more time looking for lines on the descents than watching their average speed on the climbs, and wants a bike that can take rough trails without getting flustered. It will suit the experienced mountain biker who knows how to make the most of adjustable suspension.

The LVR workshop view

Alpha aluminium, Trek's expertise. For the Gen 7 Fuel, Trek did not keep the new features for carbon alone: its most refined alloy, Alpha NEXT Platinum, gets the same modular platform. The rocker and lower shock mount can be swapped to change the geometry and end-stroke behaviour, and the ABP pivot on the rear axle helps the suspension stay active when you brake. Storage is hidden in the down tube.

	Alpha Silver	Alpha NEXT Platinum	OCLV Mountain
Level	Trek's entry-level alloy	The most refined of the Alpha alloys	Trek's mountain bike carbon
Construction	Alpha aluminium, hardtail frame	Alpha aluminium, adjustable Fuel platform	OCLV process tuned for impacts
Reference bike	Marlin 4 to 7	Fuel EX 5, 8 and 9	Fuel EX 9.8 and 9.9
What it means	Simple and affordable, no rear suspension	4.95 kg frameset in M, tough and more affordable	3.31 kg frameset in M, 1.64 kg less

Put simply: this Fuel EX 9 Eagle 90 puts the money into suspension, brakes and tyres rather than the frame. With equivalent suspension, the carbon of a Fuel EX 9.8 saves weight, not descending performance.

The Lyrik Ultimate is usually fitted to enduro bikes: on a 150 mm trail bike, it brings stiffness and mid-stroke support that reassure through sequences of steps. The DebonAir+ spring with ButterCups filters out the small vibrations that tire your hands on the long descents of the Montagne Noire.

At the rear, the Super Deluxe Ultimate RC2T has a lockout lever for fire-road climbs plus compression and rebound adjustment. We do a first set-up ride with you around the shop, then fine-tune the rebound based on your feedback.

Which Fuel should you choose?

Model	Frame	Fork / rear	Drivetrain	Weight (M)
Fuel EX 8	Alpha NEXT Platinum alloy	Fox Rhythm 36, 150 / 145 mm	SRAM Eagle 70 1x12	16.58 kg
Fuel EX 9 Eagle 90	Alpha NEXT Platinum alloy	RockShox Lyrik Ultimate, 150 / 145 mm	SRAM Eagle 90 1x12	16.58 kg
Fuel EX 9 XT	Alpha NEXT Platinum alloy	Fox Factory 36, 150 / 145 mm	Shimano XT 1x12	17.14 kg
Fuel EX 9 X0 AXS	Alpha NEXT Platinum alloy	RockShox Lyrik Ultimate, 150 / 145 mm	SRAM X0 AXS T-Type 1x12	not disclosed

Our take: compared with the Fuel EX 8, the Fuel EX 9 Eagle 90 moves to RockShox Ultimate, Maven and Maxxis for 310 g less (16.58 versus 16.89 kg). The Fuel EX 9 XT weighs 17.14 kg with Fox Factory.

LVR sizing advice

Between two sizes, we recommend the smaller one if you like playing with the terrain, the larger one if you want stability at high speed. The Line Dropper post goes from 150 mm in S to 200 mm in L and XL; the S rolls on a 27.5-inch rear wheel.

Size	M	L
Rider height (cm)	165-177	177-188
Inseam (cm)	79-83	84-89
Dropper post (mm)	170	200
Wheels front / rear (in)	29 / 29	29 / 29

Your questions

Why a Lyrik on a trail bike?	For its stiffness and support: the bike stays precise when the terrain gets rough.
Can the front travel go up to 160 mm?	The Fuel platform allows it in the MX version; we discuss it with you in the workshop based on your riding.
Which sizes in this colour?	M and L in the Trek data for this version.
Is the speckled grey discreet?	Yes, it is the most understated colour in the aluminium Fuel EX range.

The LVR Cycles verdict

A Fuel EX 9 that goes all out on suspension, with a Lyrik Ultimate worthy of an enduro bike. The understated speckled grey suits riders who prefer to let their riding do the talking.

Pros
+ Stiff Lyrik Ultimate fork
+ Maxxis Minion MaxxGrip tyres
+ Understated speckled grey

Cons
- 16.58 kg in M
- Mechanical drivetrain with no weight saving
