Who is it for?

For the cyclist who wants a single bike for commuting during the week, running errands and heading off onto the tracks at the weekend. It suits the all-weather commuter looking for a reliable bike that is easy to fit with mudguards and a rack.

The LVR workshop view

Alpha aluminium, Trek's expertise. Trek reserves the Alpha name for its in-house aluminium, and the 300 Series for the most refined of them. Shaped by hydroforming, the tubes change diameter and wall thickness where the frame works hardest, and the welds are finished for a clean look. On the Checkpoint ALR 4, this 1,878 g painted frame in size M takes a rack, mudguards, bags and the 3S chain keeper.

	Alpha 300 (Checkpoint ALR)	OCLV 500 (Checkpoint SL)	OCLV 800 (Checkmate SLR)
Level	Trek's best aluminium	Entry carbon, adventure version	Carbon honed for racing
Construction	Hydroformed tubes, finished welds	Hot OCLV compaction	Finer OCLV, aero shapes
Frame (painted)	1,878 g (M)	1,385 g (ML)	1,146 g (ML)
What it means	Takes knocks, controlled cost	Lighter, with IsoSpeed and hatch	Less room for luggage

In short: the ALR 4 keeps the same frame as the ALR 3 and puts everything into braking and drivetrain. The hydraulic brakes need less effort and less frequent adjustment, and the 11-50 cassette gives a very low gear; the weight barely changes, 10.40 kg in ML.

The CUES drivetrain is designed for longevity: thicker Linkglide sprockets and a robust LG500 chain, enough to handle thousands of kilometres of daily commuting with minimal maintenance. The 3S chain keeper stops the chain from jumping on cobbles and kerbs.

The hydraulic brakes stay just as effective in the rain, a real plus for an everyday bike, and need less adjustment than mechanical brakes. The threaded T47 bottom bracket stands up well to water and does not creak, which matters on a bike often parked outside.

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: for everyday use, the ALR 4 is the best balance in the range: hydraulic brakes and 11 speeds, without the extra cost of the ALR 5's SRAM Apex. The ALR 3, at the same weight, keeps mechanical brakes.

LVR sizing advice

If you are between two sizes, go for the smaller one if you load the front of the bike heavily, as it remains easier to handle; the larger one is more comfortable for riders with a long torso. Cranks, handlebar and stem vary with 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
Cranks (mm)	165	165	170	170	172.5	172.5
Handlebar (cm) / stem (mm)	40 / 70	40 / 80	42 / 80	42 / 90	44 / 90	46 / 100
