The LVR workshop view

OCLV Mountain carbon, the pinnacle of the Slash+ range. This 9.9 brings together the best of what Trek does on its electric enduro bike: a high-pivot OCLV Mountain frame, Line Pro 30 carbon rims and a Line Pro carbon handlebar. The 60 Nm TQ HPR60 motor is controlled from a colour display integrated into the top tube. The whole bike weighs 21.83 kg in M, with Trek's lifetime warranty on the frame.

	Fuel EXe (TQ HPR50)	Slash+ (TQ HPR60)	Rail+ (Bosch CX)
Motor torque	50 Nm	50 Nm (HPR50) or 60 Nm (HPR60)	85 Nm, up to 100 Nm via the app
Battery	TQ 360 Wh	TQ 580 Wh	Bosch PowerTube 800 Wh
Weight (M)	18.68 to 19.33 kg	20.38 to 21.83 kg	23.73 to 25.08 kg
What it means	Feels close to a non-assisted mountain bike	Light enduro, more range	Full power, more weight

Put simply: the same chassis and motor as the Slash+ 9.7, but with RockShox Ultimate suspension, a wireless drivetrain and dropper, and carbon wheels: Trek's benchmark build for lightweight electric enduro.

The 29 inch Galbraith RSL SE front tyre and 27.5 Brevard RSL SE rear tyre make up a combination designed for grip: the front bites in corners, the rear brakes in a straight line. Paired with the ZEB Ultimate and its Charger 3.1 damper, they give a very readable front end in the rock gardens of the Caroux.

The TQ colour display shows the mode, charge level and speed, and connects via Bluetooth for updates. The assist, cut off at 25 km/h as regulations require for a 250 W rated motor, stays natural thanks to the HPR60's 350 W peak. The wireless Reverb AXS post reaches 200 mm in L and XL.

Which Slash+ should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Slash+ 9.9 X0 AXS T-Type	TQ HPR50 / 580 Wh	170 / 170 mm	Wireless SRAM X0 AXS	20.88 kg
Slash+ 9.7	TQ HPR60 / 580 Wh	170 mm fork	SRAM Eagle 70 12-speed	21.58 kg
Slash+ 9.9	TQ HPR60 / 580 Wh	170 mm fork	Wireless SRAM X0 AXS	21.83 kg
Rail+ 9.8 XT Di2	Bosch CX / 800 Wh	160 / 160 mm	Wireless Shimano XT Di2	23.98 kg

Our take: this 9.9 weighs 250 g more than the Slash+ 9.7 (21.58 kg in M) but moves into a different class of suspension and goes wireless. For more power, the Bosch CX Rail+ 9.8 XT Di2 weighs 23.98 kg.

LVR sizing advice

The Reverb AXS follows the size: 150 mm in S, 175 mm in M, 200 mm in L and XL. Torn between two sizes? The shorter frame favours agility, the longer one stability in fast rock gardens; size S runs 27.5 inch wheels at both ends.

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	175	200	200
Front / rear wheels (in)	27.5 / 27.5	29 / 27.5	29 / 27.5	29 / 27.5
