Built for rides of several hours in the mountains, the Trek Rail+ 9.8 XT Di2 pairs an 800 Wh Bosch PowerTube battery with the Performance Line CX motor, on an OCLV Mountain carbon main frame with 160 mm of travel.

Who is it for?

For the adventurous mountain biker who strings together big loops, links between ranges and descents at the end of the day, when fatigue makes reliable kit essential. It also suits riders heading out on day-long touring rides.

The LVR workshop view

OCLV carbon, at the top of the Rail+ range. This 9.8 XT Di2 uses the 5th-generation OCLV Mountain main frame, compacted under heat for high stiffness and controlled weight, and pairs it with Fox Factory suspension, the most adjustable in the range. Despite the 800 Wh battery, the whole bike stays at 23.98 kg in M; the frame carries Trek's lifetime warranty.

	Carbon Rail+ (9.7 / 9.8)	Aluminium Rail+ (5 / 8)	Carbon Slash+ (TQ)
Frame	OCLV Mountain main frame	Alpha Platinum	OCLV Mountain
Drive system	Bosch CX, PowerTube 800 Wh	Bosch CX, PowerTube 800 Wh	TQ HPR60, 580 Wh
Weight (M)	23.73 to 24.18 kg	24.78 to 25.08 kg	21.58 to 21.83 kg
What it means	Lighter chassis, same motor	Gentler budget, robust frame	Gentler assist, livelier bike

Put simply: the Rail+ 9.8 XT Di2 is the most accomplished in the series, with Fox Factory, an electronic Shimano drivetrain and XT brakes; it weighs 200 g less than the 9.8 GX AXS.

The 800 Wh battery offers a generous reserve for long days, provided you match the mode to the gradient; the Bosch CX's eMTB mode does this for you by metering the assist according to your effort. The assist stops at 25 km/h, the European limit for 250 W rated. The battery comes out of the frame so you can charge it at your gîte.

Shimano XT Di2 shifts gears with no cable to tension and stays precise ride after ride, even when the mud gets in. The XT M8220 brakes and their 200 and 220 mm rotors keep their bite after a long descent towards the Orb valleys, where fatigue makes every braking point more important.

Which Rail+ should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Rail+ 9.7 Eagle 70	Bosch CX / 800 Wh	160 / 160 mm	SRAM Eagle 70 12-speed	23.88 kg
Rail+ 9.8 GX AXS	Bosch CX / 800 Wh	160 / 160 mm	Wireless SRAM GX AXS	24.18 kg
Rail+ 9.8 XT Di2	Bosch CX / 800 Wh	160 / 160 mm	Wireless Shimano XT Di2	23.98 kg
Slash+ 9.9	TQ HPR60 / 580 Wh	170 mm fork	Wireless SRAM X0 AXS	21.83 kg

Our take: at 23.98 kg in M, this 9.8 XT Di2 is only 250 g heavier than the Rail+ 9.7 XT (23.73 kg) while offering Fox Factory and an electronic drivetrain. The Rail+ 9.7 Eagle 70 weighs 23.88 kg.

LVR sizing advice

Four sizes from S to XL; the dropper grows with the frame, from 150 mm in S to 200 mm in L and XL. Torn between two sizes? The smaller one makes this 24 kg bike easier to place, the larger one more composed at high speed.

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
