Who is it for?

For the sporty cyclist who wants a fast, light gravel bike without moving to carbon, or for the road rider who wants to extend their rides onto white tracks. It suits riders who ride often and appreciate a responsive bike.

The LVR workshop view

Alpha aluminium, Trek's expertise. With its Alpha range, Trek works aluminium with the same rigour as carbon, and the 300 Series is the top of the pile. Hydroforming sculpts each tube according to the stresses it undergoes, avoiding extra material where it serves no purpose, and the welds are finely finished. The Checkpoint ALR 5 benefits from this: a 1,878 g painted frame in M, internal cables, T47 bottom bracket and UDH hanger.

	Alpha 300 (Checkpoint ALR)	OCLV 500 (Checkpoint SL)	OCLV 800 (Checkmate SLR)
Level	The pinnacle of Trek aluminium	Entry OCLV carbon	Carbon of the race Checkmate
Construction	Precise hydroforming	OCLV, thicker lay-up	OCLV, optimised lay-up
Frame (painted)	1,878 g, size M	1,385 g, size ML	1,146 g, size ML
What it means	The lightest aluminium Checkpoint	Hatch, IsoSpeed, wireless on the SL 5	Maximum efficiency, less versatile

In short: the ALR 5 is the lightest aluminium bike in the range, 9.87 kg in ML with a tubeless set-up, and only 370 g more than the carbon Checkpoint SL 5 AXS. The difference comes down to IsoSpeed, the storage hatch and wireless shifting, which the ALR does not have.

The mechanical Apex XPLR groupset offers an 11-44 range over 12 speeds, with tighter steps than the CUES on the ALR 3 and 4, which helps you stay in the right rhythm when riding fast. Cable shifting remains easy to adjust yourself, even at the side of a track in the Minervois.

Quoted at 9.87 kg in ML with sealant and without inner tubes, the ALR 5 makes the most of tubeless: less rotating weight, lower pressure and fewer punctures on garrigue thorns. The SRAM Apex hydraulic brakes modulate braking finely on rocky descents.

Which Checkpoint should you choose?

Model	Frame	Drivetrain	Wheels	Weight (ML)
Checkpoint ALR 3	Alpha 300 alloy	Shimano CUES 1x10, mechanical brakes	Aluminium Paradigm 23	10.41 kg
Checkpoint ALR 4	Alpha 300 alloy	Shimano CUES 1x11, hydraulic brakes	Aluminium Paradigm 23	10.40 kg
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

Our take: at 9.87 kg in ML, the ALR 5 is 530 g lighter than the ALR 4. The carbon Checkpoint SL 5 AXS is only 370 g lighter, but adds IsoSpeed, the hatch and wireless shifting.

LVR sizing advice

If you are between two sizes, the smaller one makes the bike livelier when accelerating, the larger one more settled on long tracks. Cranks go from 165 to 172.5 mm, and the handlebar and stem grow with the frame.

Rider height (cm)	143-158	158-164	164-177	177-188	188-194	194-203

Your questions

Why not carbon?	The ALR 5 is very close in weight; carbon mainly brings IsoSpeed, the hatch and wireless shifting.
Supplied tubeless?	The quoted weight corresponds to a tubeless set-up, which we carry out in our workshop.
Fast enough on the road?	Yes, with narrower tyres it makes an excellent versatile road bike.
Is the fade finish delicate?	No, it is cared for like any standard paint, with a gentle product.

The LVR Cycles verdict

The sportiest aluminium Checkpoint, light and well equipped with its 12-speed SRAM Apex and hydraulic brakes. Its blue-green fade gives it real personality.

Cons
- No IsoSpeed or hatch
- Mechanical cable-operated drivetrain
