The LVR workshop view

OCLV carbon, Trek's signature. The Domane+ SL 9 AXS keeps the OCLV Series 500 carbon of the other Domane+ SL models: here, the weight saving comes from the spec, Aeolus RSL 37 wheels and a RED groupset, rather than from a more expensive carbon. The process remains Trek's own, layers compacted under pressure and heat to avoid any internal flaws, with a lifetime warranty on the frame.

	Domane+ SL (OCLV 500)	Domane+ SLR (OCLV 800)	Domane+ ALR (aluminium)
Level	Lighter new generation	High-end Domane+ carbon	Entry to TQ assist
Construction	OCLV 500, TQ HPR40 motor	OCLV 800, TQ HPR60 motor	Alpha Series 300, TQ HPR60 motor
Reference bike	Domane+ SL 9 AXS: 11.00 kg (ML)	Domane+ SLR 7: 12.65 kg (56)	Domane+ ALR 5: 14.39 kg (ML)
What it changes	40 Nm, wireless 1x13	60 Nm, Shimano Di2 2x12	Heavier, SRAM Apex XPLR 1x12

In short: the SL 9 AXS is the lightest Domane+ SL, at 11.00 kg in ML, and the only one to get the SRAM RED XPLR eTap AXS drivetrain. The frame and HPR40 motor are those of the SL 6 and SL 7: what you pay for here is Aeolus RSL wheels and a RED groupset.

When you are watching your heart rate or power, steep gradients are a problem: the assist lets you stay in your endurance zone where you would otherwise have had to dig deep. On the roads of the Espinouse and the Caroux, the HPR40's help flattens the gradients and the 10-46 cassette maintains a supple cadence.

On the descents, the feel remains that of a Domane: light carbon wheels, 35 mm tyres that offer grip, disc brakes on 160 mm SRAM Paceline X rotors. The motor no longer pushes above 25 km/h, leaving the bike free on the long straights.

Which Domane+ should you choose?

Model	Frame	Motor	Drivetrain	Weight (size)
Domane+ SL 7 AXS	OCLV 500 carbon	TQ HPR40, 40 Nm	SRAM Force XPLR AXS 1x13	11.47 kg (ML)
Domane+ SL 9 AXS	OCLV 500 carbon	TQ HPR40, 40 Nm	SRAM RED XPLR AXS 1x13	11.00 kg (ML)
Domane+ SLR 9	OCLV 800 carbon	TQ HPR60, 60 Nm	Shimano Dura-Ace Di2 2x12	11.84 kg (56)
Domane+ SLR 7	OCLV 800 carbon	TQ HPR60, 60 Nm	Shimano Ultegra Di2 2x12	12.65 kg (56)

Our take: the SL 9 AXS (11.00 kg in ML) offers 40 Nm; the Domane+ SLR 9 (11.84 kg in 56) moves up to 60 Nm with the HPR60 and a Dura-Ace Di2 double chainset. To stay below an effort threshold, the gentler push of the HPR40 is enough on most cols.

LVR sizing advice

The Domane+ SL comes in XS to XL. Trek puts the ML between 173 and 179 cm and the L between 179 and 188 cm; handlebar width (36 to 42 cm) and stem length (80 to 120 mm) change with the size. If you are between two sizes, a measurement in store will settle it.

Size	XS	S	M	ML	L	XL
Rider (cm)	143-158	158-162	162-173	173-179	179-188	188-199
Inside leg (cm)	67-74	74-76	76-81	81-84	84-88	88-100
Handlebar (cm)	36	38	40	40	42	42
Stem (mm)	80	90	100	110	110	120
