The LVR workshop view

OCLV carbon, Trek's signature. OCLV is Trek's in-house process, in place since 1992: heat and pressure drive out the air trapped between the fibre sheets, and the higher the series number, the less material is needed for a given stiffness. The Speed Concept SLR 7 AXS uses Series 800, which was long the top of the brand's road range. Here it makes room for a Bento box and a down tube compartment without weakening the frame, which carries a Trek lifetime warranty.

	OCLV 800 (Speed Concept SLR)	OCLV 900 (Madone SLR)	OCLV 500 (Madone SL)
Level	Trek's former top-end road carbon	Trek's most advanced carbon	Entry-level road carbon
Construction	Lay-up optimised for large-section aero tubes	3D moulding, fewer fibre overlaps	Same process, slightly more material
Reference bike	Frame 1,522 g painted + fork 410 g	Madone SLR: frame 796 g (ML) + fork 350 g	Madone SL: frame 1,054 g (ML) + fork 363 g
What it means	Stiff and durable, integrated storage and IsoSpeed	Up to 20% stronger than OCLV 800	Heavier, more affordable budget

In short: a triathlon frame is not chosen by the gram. The 1,522 g of the Speed Concept are explained by deep sections and integration, assets that save far more time than a hundred grams or so on a fast course.

The power meter fitted as standard changes the way you race: rather than going by feel or by speed, which the wind distorts, you hold a target power. On the bike leg of a triathlon, that is often what stops you going out too hard and paying for it on the run.

The 48/35 chainset and 10-33 cassette offer a top gear comparable to 52x11 and an easier bottom gear: useful on courses that climb towards the Hauts Cantons. The AXS batteries charge on the derailleurs; we update the firmware and pair the power meter with your bike computer.

Which Speed Concept should you choose?

Model	Carbon	Drivetrain	Wheels	Weight (size)
Speed Concept SLR 7	OCLV 800	Shimano Ultegra Di2	Aeolus Pro 37	8.97 kg (M)
Speed Concept SLR 7 AXS	OCLV 800	SRAM Force AXS + power meter	Aeolus Pro 51	9.02 kg (M)
Speed Concept SLR 9	OCLV 800	Shimano Dura-Ace Di2	Aeolus RSL 51	n/a (frame 1,522 g)
Speed Concept SLR 9 AXS	OCLV 800	SRAM RED AXS + power meter	Aeolus RSL 51	n/a (frame 1,522 g)

Our take: compared with the SLR 7, this model adds a power meter, 51 mm rims and a Bento box for just 50 g more. The SLR 9 AXS steps up to RED AXS and RSL wheels, with the same power meter principle.

LVR sizing advice

Between two sizes, do not decide from the chart alone: the aero position depends on your flexibility and the height of the extensions. We set up the mid-rise bar and seatpost offset during the bike fit.

Size	S	M	L	XL
Rider height (cm)	154-167	167-175	175-186	186-198
Inseam (cm)	72-80	77-83	82-88	87-93
Cranks (mm)	n/a	170	170	172.5
Seatpost	short	tall	tall	tall

Your questions

Does the power meter work with GPS computers?	Yes, it communicates with common ANT+ and Bluetooth computers.
Charging the batteries?	Yes, SRAM AXS charger supplied, with a battery life of several weeks.
Useful for a beginner?	Yes, if you follow a plan; otherwise the SLR 7 is enough.
Where do I keep my inner tube?	In the storage compartment integrated into the frame's down tube.

The LVR Cycles verdict

The Speed Concept that turns every ride into a measured session. For a triathlete who trains seriously, the built-in power meter alone justifies choosing this version.

Pros
+ Power meter as standard
+ Fast 51 mm rims
+ Integrated Bento box and storage

Cons
- Rims more sensitive to crosswinds
- 9.02 kg in M, not the lightest
