Trek Speed Concept SLR 9 AXS matte deep smoke: the long-distance weapon

Finished in Matte Deep Smoke, a dark smoked grey with a matte look, the Trek Speed Concept SLR 9 AXS combines an OCLV Series 800 frame, SRAM RED AXS E1 with power meter and Aeolus RSL 51 wheels. As Trek France publishes no complete weight, we quote the frame at 1,522 g painted and the fork at 410 g. On this colour, Trek specifies a single crank length per size, from 160 to 172.5 mm.

Who is it for?

For the Ironman athlete who wants to manage their race to the nearest watt over 180 km and already has solid experience of the aero position. It also suits the triathlete who trains a lot alone and analyses every session.

The LVR workshop view

OCLV carbon, Trek's signature. Developed by Trek in the early 1990s, OCLV involves pressing and heating the carbon layers until every air bubble is driven out. The Speed Concept SLR 9 AXS, the best-equipped version in the range, nevertheless shares the same OCLV Series 800 frame as the SLR 7: moving up the range means a better drivetrain and wheels. 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

The key point: the top-end Speed Concept doesn't change carbon, and that makes sense. On a triathlon course, aerodynamic drag matters far more than frame weight; the extra cost of the SLR 9 AXS goes into RED AXS and RSL rims.

Over long distances, the power meter acts as a safeguard: it stops you getting carried away in the first kilometres, when your legs are fresh. Combined with the frame's integrated storage, it lets you ride self-sufficiently without losing sight of your pacing strategy.

The RSL 51 wheels offer a good compromise between aerodynamics and handling, but need attention when the sea wind blows in gusts along the coast. We check spoke tension and bearing condition at every service before an important race.

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: for Ironman, this SLR 9 AXS combines a power meter, storage and RED AXS; if the budget needs to stay reasonable, the SLR 7 AXS keeps the power meter and Bento box for 9.02 kg in M.

LVR sizing advice

A triathlon position is built around the pelvis and forearms: if you are between two sizes, we compare reach and extension height during the bike fit before deciding.

Inseam (cm)	72-80	77-83	82-88	87-93
Cranks (mm)	160	170	170	172.5
Seatpost	short	tall	tall	tall
