Trek Fuel EX 9 XT Di2 Lithium Grey: Shimano electronic precision

No more derailleur cable: the Trek Fuel EX 9 XT Di2 Gen 7 controls its twelve speeds electronically with Shimano XT Di2. Its Alpha NEXT Platinum chassis carries a 36 Factory GRIP X2 (150 mm) and a Float X Factory (145 mm), all slowed by XT M8220 callipers. Trek measures 16.88 kg on a size M; the Lithium Grey/Trek Black Splatter colour blends graphite grey with black splashes.

Who is it for?

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.

XT Di2 shifts electronically: the shifter sends the command to the M8250 derailleur, which positions itself precisely on every shift. No more cable tension adjustments or hesitant shifts after a muddy ride.

We carry out the Di2 configuration and updates in the workshop, and adjust how the shifter behaves to suit your preferences. The drivetrain keeps the durable XT 10-51 cassette, which is easy 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: compared with the cable-operated XT, this electronic version saves 260 g. You need the OCLV Mountain carbon of the 9.8 XT to get down to 15.28 kg, but with a conventional derailleur.

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	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
