Who is it for?

For the mountain biker who heads out for the day in the Espinouse or the Montagne Noire, with several hours of climbing and proper descents on the menu, and prefers to carry their repair kit in the bike rather than on their back. It suits riders from 155 to 195 cm.

The LVR workshop view

Alpha NEXT Platinum aluminium, the pinnacle of Trek alloy. Trek grades its aluminium in three tiers: Alpha Silver on the Marlin, Alpha Platinum above it, and Alpha NEXT Platinum, reserved for the 7th generation of the Fuel. It is the latter that forms the base of the Fuel MX 9 Eagle 90. On the Fuel EX of the same generation, the alloy frameset weighs 4.95 kg in M, against 3.31 kg for the carbon version: the gap is real, but a well-made alloy frame takes rocks and crashes without leaving you worrying about the slightest invisible crack.

	Alpha NEXT Platinum (Fuel 9)	OCLV Mountain (Fuel 9.8 / 9.9)	Alpha Platinum (Slash 8)
Level	Trek's best aluminium	Trek's mountain bike carbon	High-end alloy, one step below NEXT
Designed to	Take knocks at a sensible cost	Save weight, resist impacts	Aluminium enduro frames
Gen 7 Fuel EX frameset (M)	4.95 kg	3.31 kg	not applicable
What it means	Heavier, but unbothered by small knocks	1.64 kg less on the frameset	Previous aluminium generation

Put simply: with the same drivetrain, this alloy Fuel MX amounts to a complete bike capable of the same descents as the carbon 9.8. The extra grams are felt mainly on long climbs; on descents, the stability of a slightly heavier frame is no bad thing.

The integrated storage holds an inner tube, tyre levers and a multi-tool: the backpack can stay in the garage in hot weather, which eases the strain on your shoulders over a long day. The frame is also protected at the down tube against flying stones, common on schist tracks.

On the climbs, the Eagle 90 and its 52-tooth sprocket let you keep a steady rhythm on long slopes. The Bontrager Line Dropper post, with 150 to 200 mm of travel depending on size, drops right out of the way at the top of the pass to free up room for your hips on the descent.

Which Fuel should you choose?

Model	Frame	Travel rear / front	Drivetrain	Weight (M)
Fuel EX 9 Eagle 90	Alpha NEXT Platinum alloy	145 / 150 mm	SRAM Eagle 90 1x12	16.58 kg
Fuel MX 9 Eagle 90 (Fox)	Alpha NEXT Platinum alloy	150 / 160 mm	SRAM Eagle 90 1x12	16.78 kg
Fuel MX 9 XT	Alpha NEXT Platinum alloy	150 / 160 mm	Shimano XT 1x12	16.91 kg
Fuel LX 9 Eagle 90	Alpha NEXT Platinum alloy	160 / 170 mm	SRAM Eagle 90 1x12	17.38 kg

Our take: for big days out, this Fuel MX offers more margin on the descents than the Fuel EX 9 Eagle 90 (16.58 kg) for only 200 g more. The Fuel LX 9 Eagle 90, at 17.38 kg, makes less sense if you ride all day.

LVR sizing advice

Hesitating between two sizes: the smaller one makes the bike playful in tight corners, the larger one makes it more composed at high speed. Dropper post travel increases with size, from 150 to 200 mm.

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 of travel)	150	170	200	200

Your questions

What can I store in the frame?	An inner tube, tyre levers and a small tool: enough for repairs without a bag.
Enough gearing for the climbs?	Yes, the 30x52 lets you climb the steepest tracks seated.
How long in the saddle?	A full day is feasible, provided the saddle is carefully set up.
Is the green discreet?	Yes, this speckled matte fir green blends into forest landscapes.

The LVR Cycles verdict

A companion for big loops, carrying the essentials in its frame and keeping plenty in reserve for the descents. Its matte fir green speckled with blue sage is elegant and discreet.
