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.
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.
| 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.
