Trek Checkmate SLR 9 AXS Hex Blue: managing your effort to the watt

With its OCLV 800 Series carbon frame, its SRAM RED XPLR AXS 1x13 groupset with a power-measuring chainset and its Aeolus RSL 37V wheels, the Trek Checkmate SLR 9 AXS weighs 7.55 kg in size ML. It is as much a training tool as a race bike: every ride delivers usable data. The Matte Hex Blue/Plasma Grey Pearl finish pairs a deep matt blue with a pearlescent grey that catches the light.

Who is it for?

For the cyclist following a structured training plan, alone or with a coach, who wants reliable power data on dirt as well as on the road. It will also appeal to the former road racer who already knows their training zones and wants to find them again on gravel.

The LVR workshop view

OCLV carbon, Trek's signature. The OCLV process, used by Trek since 1992, presses the fibre sheets under heat and pressure to eliminate micro-voids. On the Checkmate SLR, Trek uses the 800 Series: an optimised lay-up that produces a painted frame of 1,146 g in ML, stiff enough to handle out-of-the-saddle efforts on a broken track. Like all OCLV frames, it benefits from Trek's lifetime warranty.

	OCLV 800 (Checkmate SLR)	OCLV 500 (Checkpoint SL)	OCLV 900 (Madone / Domane SLR)
Level	Trek's top-tier gravel	Entry-level carbon	Trek's most refined carbon
Construction	Optimised lay-up, little superfluous material	Same process, more generous lay-up	3D moulding, fewer overlaps
Reference bike	Checkmate SLR 9 AXS: 7.55 kg (ML)	Checkpoint SL 7 AXS: 9.33 kg (ML)	Reserved for SLR road bikes
What it means	Frame + fork 1,561 g, race geometry	Frame + fork 1,921 g, adventure mounts	Up to 20% stronger than OCLV 800

In short: the SLR 9 AXS frame is the same as on every Checkmate SLR, and it is the spec that makes the difference. The RED XPLR, the RSL wheels and the AirLoom saddle account for most of the 920 g gap with the SLR 7 AXS; as for OCLV 900, Trek keeps it for its road bikes.

On gravel, heart rate and speed are poor guides: the surface changes constantly and the same pace can cost twice as much energy in sand as on a hard-packed track. The power meter built into the RED XPLR chainset measures your real effort, so you can pace a forest-track climb in the Montagne Noire without blowing up at the top.

On long events, power also helps you manage fuelling and avoid going out too hard. We pair the power meter with your computer, set up the SRAM AXS app to display battery levels and show you how to run a calibration before an important session.

Which Checkmate should you choose?

Model	Carbon	Drivetrain	Wheels	Weight (size)
Checkpoint SL 7 AXS	OCLV 500	SRAM Force XPLR AXS 1x13	Carbon Aeolus Elite 35V	9.33 kg (ML)
Checkmate SLR 7 AXS	OCLV 800	SRAM Force XPLR AXS 1x13 + power meter	Carbon Aeolus Pro 3V	8.47 kg (ML)
Checkmate SLR 9 AXS	OCLV 800	SRAM RED XPLR AXS 1x13 + power meter	Carbon Aeolus RSL 37V	7.55 kg (ML)
Boone 5 (cyclocross)	OCLV 600	SRAM Apex 1x12	Bontrager Paradigm Comp 25	8.50 kg (56)

Our take: the power meter comes on both Checkmate SLR models: choosing the SLR 9 AXS is mainly about saving 920 g thanks to the RED groupset, the RSL wheels and the AirLoom saddle, not about extra data.

LVR sizing advice

Race geometry: if you are between two sizes, the smaller one gives a livelier bike in tight corners, the larger one more stability on fast descents. The one-piece bar-stem cannot be adjusted for length, which is why a bike fit before purchase is worthwhile.
