Trek Fuel EX 5 Lithium Grey: a sound base for upgrading your bike

Behind its sensible spec, the Trek Fuel EX 5 Gen 7 hides the Alpha NEXT Platinum aluminium frame that Trek also fits to the Fuel EX 8 and 9. A 150 mm RockShox Recon fork, a RockShox Deluxe Select shock for 145 mm of travel and Shimano Deore 1x12 equip it, for a quoted weight of 16.88 kg in size M. Its Lithium Grey/Trek Black Splatter paintwork blends a dark lithium grey with black spatters like mud splashes.

Who is it for?

For the pragmatic mountain biker who would rather invest in a good frame and upgrade the rest as it wears out than buy a highly specced bike straight away. It is also an excellent choice for a first full-suspension bike shared between family rides and sportier outings.

The LVR workshop view

Alpha aluminium, Trek's expertise. Trek groups its alloys into three tiers: Alpha Silver for the Marlin, Alpha Platinum for the Procaliber and Slash 8, then Alpha NEXT Platinum, reserved for the Gen 7 Fuel. So the Fuel EX 5 does not get a cut-price frame: it is the same structure as on the Fuel EX 8 and 9, with its kinematics, storage hatch and progression adjustments. Only the kit fitted to it changes.

	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: buying a Fuel EX 5 means buying the frame from the top of the aluminium range with simpler components. The day the fork or shock shows its limits, you can replace them without changing bikes; the 4.95 kg frameset in M is the same as on the more expensive versions.

The frame is the one part you do not change: on this Fuel EX 5, it already has adjustable progression, ISCG 05 mounts and down tube storage. A stiffer fork, 4-piston brakes or lighter wheels can come later, without losing anything of what makes the bike handle the way it does.

The flecked grey is a practical choice: everyday chips and scratches barely show. On the maintenance side, the threaded BSA bottom bracket and standard bearings avoid nasty surprises in the workshop, and the 12-speed Deore chain remains cheap to replace.

Which Fuel should you choose?

Model	Frame	Fork / rear	Drivetrain	Weight (M)
Fuel EX 5	Alpha NEXT Platinum alloy	RockShox Recon 150 / 145 mm	Shimano Deore 1x12	16.88 kg
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 9.8 XT	OCLV Mountain carbon	Fox Factory 36, 150 / 145 mm	Shimano XT 1x12	15.28 kg

Our take: with an identical frame, the difference from the Fuel EX 8 comes down to the fork, shock and brakes, for a 300 g gap in M. The Fuel EX 9.8 XT moves to OCLV Mountain carbon and 15.28 kg.

LVR sizing advice

The Fuel EX is chosen mainly by rider size: if you are between two sizes, the smaller makes the bike more playful in switchbacks, the larger more stable on fast descents. The dropper post is matched to each size; in S, the bike runs a 29-inch front and 27.5-inch rear wheel.

Size	S	M	L	XL
Rider height (cm)	155-165	165-177	177-188	188-195
Inseam (cm)	74-78	79-83	84-89	89-91
Dropper post (mm)	150	170	170	170
Wheels front / rear (in)	29 / 27.5	29 / 29	29 / 29	29 / 29

Your questions

Which upgrades come first?	Tyres and tubeless first, then the brakes; the fork comes next if you do a lot of descending.
Can a chain guide be fitted?	Yes, the frame has ISCG 05 mounts.
What can I store in the frame?	An inner tube, a tyre lever and a small tool, in the down tube hatch.
Does the flecked grey age well?	Very well: the black spatters hide small scratches.

The LVR Cycles verdict

A smart entry point into the Fuel family: you start with the right frame and upgrade the rest at your own pace. The lithium grey flecked with black is understated and forgiving of wear and tear.

Pros
+ Frame shared with the Fuel EX 8 and 9
+ ISCG 05 mounts and integrated storage
+ Flecked finish that hides dirt

Cons
- Braking only just adequate for long descents
- 16.88 kg in M
