Trek Checkpoint SL 5 AXS black: your way into wireless carbon gravel

The Trek Checkpoint SL 5 AXS Gen 3 is the entry-level Checkpoint in OCLV 500 Series carbon, fitted with the wireless SRAM Apex XPLR AXS 1x12 drivetrain and 42 mm Girona Pro tyres, weighing 9.50 kg in size ML. It keeps all the platform's strengths: IsoSpeed, a down tube storage hatch and tyre clearance up to 50 mm. The Trek Black/Matte Carbon Smoke version plays it understated, with gloss black alternating with a matt smoked carbon grey.

Who is it for?

For the road cyclist who wants to leave the tarmac at weekends without giving up a light, lively bike, or for the rider already on an aluminium gravel bike who wants to move to carbon and wireless in one go. It is equally suited to mixed road-and-track rides and to first multi-day getaways.

The LVR workshop view

OCLV carbon, Trek's signature. Since 1992, Trek has cured its fibre sheets under pressure and at high temperature to drive out micro-voids, the bubbles that weaken a frame. The higher the series number, the more optimised the lay-up and the less material is needed for a given stiffness. The Checkpoint SL 5 AXS uses OCLV 500 Series: 1,385 g for the painted frame in ML and 536 g for the fork, with Trek's lifetime warranty on the frame.

	OCLV 500 (Checkpoint SL)	OCLV 800 (Checkmate SLR)	Alpha 300 (Checkpoint ALR)
Level	Trek's entry carbon, adventure version	Race gravel carbon	Trek's premium aluminium
Construction	OCLV process, generous lay-up	OCLV process, finer lay-up	Hydroformed tubes, neat welds
Frame (painted)	1,385 g in ML + fork 536 g	1,146 g in ML + fork 415 g	1,878 g in M
What it means	Robust, plenty of mounts, IsoSpeed	Lighter and more aero, less luggage	Heavier, gentler on the budget

In short: compared with the aluminium Checkpoint ALR 5, the SL 5 AXS is 370 g lighter in size ML and gains IsoSpeed, the storage hatch and wireless shifting. The Checkmate's OCLV 800 carbon is aimed at a different rider, one who races rather than one who sets off loaded.

Going wireless on a gravel bike is no gimmick: with no derailleur cable, nothing clogs up in the housing after a dusty ride through the vineyards around Béziers, and the adjustment stays stable over time. The Apex XPLR AXS drivetrain keeps the PG-1231 11-44 cassette, which is robust and easy to replace, keeping running costs down.

The 40-tooth single chainring paired with the 44-tooth sprocket lets you climb steep track ramps without putting a foot down, and the 40x11 is enough to keep up with a group on the road. On broken tarmac, the carbon seatpost and IsoSpeed filter out the vibrations that tire your lower back far better than an aluminium frame.

Which Checkpoint should you choose?

Model	Frame	Drivetrain	Wheels	Weight (ML)
Checkpoint ALR 5	Alpha 300 alloy	Mechanical SRAM Apex XPLR 1x12	Aluminium Paradigm 23	9.87 kg
Checkpoint SL 5 AXS	OCLV 500	Wireless SRAM Apex XPLR AXS 1x12	Aluminium Paradigm SL	9.50 kg
Checkpoint SL 6 AXS	OCLV 500	Wireless SRAM Rival XPLR AXS 1x13	Aluminium Paradigm Comp 25	9.49 kg
Checkpoint SL 7 AXS	OCLV 500	Wireless SRAM Force XPLR AXS 1x13	Carbon Aeolus Elite 35V	9.33 kg

Our take: compared with the aluminium ALR 5, the SL 5 AXS brings carbon, IsoSpeed and wireless shifting for 370 g less. The SL 6 AXS moves to 13 speeds for the same weight; the SL 7 AXS drops to 9.33 kg with carbon wheels.

LVR sizing advice

If you are between two sizes, choose the smaller one for nimble handling on narrow trails, the larger one if you mainly ride wide tracks and long distances. Handlebar width, stem length and saddle width change with the size.

Size	XS	S	M	ML	L	XL
Rider height (cm)	143-158	158-164	164-177	177-188	188-194	194-203
Inseam (cm)	67-74	74-77	77-83	83-88	88-91	91-95
Handlebar (cm) / stem (mm)	40 / 60	42 / 70	42 / 80	44 / 80	44 / 90	46 / 100
Saddle (mm)	155	155	145	145	145	145

Your questions

Fast enough on the road?	Yes for endurance rides; with narrower 35 to 38 mm tyres, it becomes a genuinely versatile road bike.
Charging the derailleur?	Yes, the SRAM AXS battery charges with the supplied charger, a few times a season.
Can it be set up tubeless?	Yes, the rims and tyres are Tubeless Ready: we do the set-up in our workshop.
Is matt black delicate?	Clean the matt areas with a gentle wax-free product; avoid glossy polishes.

The LVR Cycles verdict

The ideal gateway into Trek carbon gravel, with a wireless drivetrain that is easy to live with. Its black and matt carbon grey give it a discreet, elegant look.

Pros
+ OCLV carbon and IsoSpeed at this level
+ Wireless AXS with no cable maintenance
+ Understated black finish

Cons
- Entry-level aluminium wheels
- Only 12 speeds
- 9.50 kg: not a featherweight
