Trek Checkpoint ALR 4 Living Coral: low gearing for the traveller

The Trek Checkpoint ALR 4 Gen 3 pairs an Alpha 300 Series aluminium frame and a carbon fork with a Shimano CUES 1x11 drivetrain with an 11-50 cassette and hydraulic disc brakes, weighing 10.40 kg in size ML. It is the ALR with the biggest sprocket in the range. Its Living Coral colour is a vivid coral, between pink and orange, that can be spotted from afar.

Who is it for?

For the touring cyclist who sets off loaded, with front and rear panniers, and for whom ease on the climbs matters more than speed. It also suits the less trained cyclist who wants to tackle hilly tracks without apprehension.

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 50-tooth sprocket paired with the 40-tooth chainring gives a ratio below one to one: with each pedal stroke, the wheel turns less than once. With a loaded bike on the climbs towards the Caroux, this gearing lets you keep a reasonable cadence where an 11-44 would force you to grind.

The Shimano CUES hydraulic brakes modulate power better than a mechanical brake, with reduced lever effort, which is reassuring on descents with a bike loaded with panniers. The 160 mm RT54 rotors wear slowly and are easy to replace.

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: compared with the ALR 3, the ALR 4 gains hydraulic brakes and an extra gear, for the same weight. The ALR 5 is 530 g lighter, but its 11-44 cassette is less forgiving for loaded touring.

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

Your questions

Enough top gear on the road?	The 40x11 is more than enough for a good pace on the road when touring.
Front rack possible?	Yes, the carbon fork has the necessary mounts.
Maintaining hydraulic brakes?	An occasional bleed, which we carry out in our workshop.
Is the coral too loud?	That is precisely a visibility advantage on the road and in the forest.
