Trek Madone SLR 9 marbled purple: speed and comfort on long rides

The Trek Madone SLR 9 Gen 8 combines an OCLV Series 900 frame, Shimano Dura-Ace Di2 2x12 and Aeolus RSL 51 carbon wheels for 7.05 kg in size ML, sealant included. Its 28 mm cotton-casing Aeolus RSL RD tyres and IsoFlow make it far smoother than the aero bikes of a few years ago. The Purple Phaze/Amethyst Marble finish unfolds a pearlescent purple veined with amethyst highlights.

The LVR workshop view

OCLV carbon, Trek's signature. OCLV is the name of Trek's in-house process since 1992: compacting the carbon sheets at high temperature and under strong pressure so that no voids remain between them. The Madone SLR models get Series 900, the brand's most refined. The higher the number, the more optimised the lay-up and the fewer fibres are needed to reach the target stiffness: the frame and fork of this SLR 9 therefore total 1,146 g. The frame is covered for life by Trek.

	OCLV 900 (Madone SLR)	OCLV 500 (Madone SL)	OCLV 800 (Speed Concept)
Level	Trek's most refined carbon	Entry-level road carbon	Trek's former top-end road carbon
Construction	3D moulding, reduced ply overlaps	Same process, more generous lay-up	Proven lay-up, integration comes first
Reference bike	Madone SLR: painted frame 796 g (ML), fork 350 g	Madone SL: painted frame 1,054 g (ML), fork 363 g	Speed Concept SLR: painted frame 1,522 g
What it means	271 g less than the SL on frame and fork; up to 20% stronger than OCLV 800	Same aero shapes, separate bar and stem, gentler budget	Still very high-performing, reserved for triathlon at Trek

Put simply: the OCLV 500 of the Madone SL remains an excellent carbon; it simply needs about 258 g more on the frame for equivalent stiffness. On a 7.05 kg machine like this one, that saving counts directly in the total and in the bike's lively feel out of the saddle.

170 tpi cotton-casing tyres follow road irregularities better than a standard tyre: the feel is more supple and the efficiency better. Combined with the 28 mm width, compared with 25 mm on the former Madone, they turn the rough roads of the Minervois into far more pleasant terrain.

On this colourway, Trek lists cranks one step longer than on other colours, from 165 mm in XS to 172.5 mm in L and XL: worth bearing in mind if you are between two sizes. Tubeless fits easily on the Aeolus RSL rims; we set it up with a sealant suited to the intense summer heat.

Which Madone should you choose?

Model	Carbon	Drivetrain	Wheels	Weight (size)
Madone SLR 7	OCLV 900	Shimano Ultegra Di2	Aeolus Pro 51 carbon	7.52 kg (ML)
Madone SLR 9	OCLV 900	Shimano Dura-Ace Di2	Aeolus RSL 51 carbon	7.05 kg (ML)
Madone SLR 9 AXS	OCLV 900	SRAM RED AXS E1 + power meter	Aeolus RSL 51 carbon	7.00 kg (ML)
Madone SLR 9 AXS 1x	OCLV 900	SRAM RED E1 1x12 + power meter	Aeolus RSL 37 carbon	6.40 kg (ML)

Our take: for long distances, the SLR 9 at 7.05 kg offers the same compliance as the SLR 9 AXS; the choice comes down to the groupset brand. The SLR 7 Ultegra Di2, 470 g heavier, remains a very comfortable base.

LVR sizing advice

The Madone is set up like a race bike: if you are hesitating, the smaller size will put you lower and more compact, the larger one more stretched out and slightly higher. There is no separate stem here: the one-piece cockpit is chosen at the same time as the frame.
