The LVR workshop view

Alpha aluminium, Trek's expertise. The Fuel EX 9 XT Di2 pairs Shimano's electronic groupset with Trek's most advanced aluminium, Alpha NEXT Platinum, the top tier above Alpha Platinum and Alpha Silver. The frame retains all the Gen 7 options: adjustable progression, geometry changes via interchangeable parts, a down tube storage hatch, a ZS headset and an easy-to-maintain threaded BSA bottom bracket.

	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

In short: the Di2 version weighs 16.88 kg in M, 260 g less than the mechanical Fuel EX 9 XT, with identical suspension and brakes. The aluminium frame remains 1.64 kg heavier than the carbon kit, but it gives you electronics without moving to carbon.

An electronic drivetrain updates like a smartphone: new features, fixes, fine-tuning. We carry out these updates in the workshop and check the drivetrain at every service, so the bike is always running perfectly.

After a crash, the M8250 derailleur is easy to check, and electronic diagnostics quickly identify any problem. The cassette and chain remain conventional XT parts, simple and inexpensive to replace.

Which Fuel should you choose?

Model	Frame	Fork / rear	Drivetrain	Weight (M)
Fuel EX 9 XT	Alpha NEXT Platinum alloy	Fox Factory 36, 150 / 145 mm	Shimano XT 1x12	17.14 kg
Fuel EX 9 XT Di2	Alpha NEXT Platinum alloy	Fox Factory 36, 150 / 145 mm	Shimano XT Di2 1x12	16.88 kg
Fuel EX 9 X0 AXS	Alpha NEXT Platinum alloy	RockShox Lyrik Ultimate, 150 / 145 mm	SRAM X0 AXS T-Type 1x12	not disclosed
Fuel EX 9.8 XT	OCLV Mountain carbon	Fox Factory 36, 150 / 145 mm	Shimano XT 1x12	15.28 kg

Our take: in the aluminium range, this Di2 slots in between the Eagle 90 (16.58 kg) and the cable-operated XT (17.14 kg). The X0 AXS, its SRAM equivalent, has no published weight.

LVR sizing advice

If you are between two sizes, go for the smaller if your trails are slow and technical, the larger if you prioritise speed and stability. Post travel follows frame size; the S gets a 27.5-inch rear wheel to keep clearance.

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	200	200
Wheels front / rear (in)	29 / 27.5	29 / 29	29 / 29	29 / 29
