The Trek Domane AL 4 Gen 4 brings together an Alpha Series 100 aluminium frame, a carbon fork and Shimano Tiagra 2x11, for a weight of 10.10 kg in size 56. Lively enough to keep up with a group, comfortable enough to finish fresh, it quickly finds its place on Saturday morning rides. The Fury Red colour, a bright, bold red, doesn't go unnoticed at the start of the ride.

For the cyclist who has just joined a club and wants to hold their own in the intermediate group, the rider taking part in their first organised rides, or anyone who often rides with others and wants smooth, jolt-free shifting. It also suits young adults moving from mountain biking to the road.
Alpha aluminium, Trek's expertise. Under the Domane AL 4, Trek uses its Alpha Series 100 alloy, chosen to withstand everyday use and accept mudguards, a top tube bag or wider tyres. The fork is carbon, steerer included, which softens the steering on rough surfaces. Universal UDH derailleur hanger and thru axles: spare parts are easy to find, a detail that matters on the day of a crash.
| Alpha 100 (Domane AL) | Alpha 300 (Émonda ALR) | OCLV 500 carbon (Domane SL) | |
| Level | The Domane AL aluminium | Trek's lightest aluminium | Entry-level road carbon |
| Construction | Welded tubes, carbon fork, plenty of mounts | Invisible Weld technology, the look of a carbon frame | Layers compacted under heat and pressure |
| Reference bike | Domane AL 4: 10.10 kg (size 56) | Émonda ALR 5: 9.17 kg (size 56) | Domane SL 5 Gen 5: 8.84 kg (size ML) |
| What it means | Mudguards possible, versatility, sensible budget | Livelier and lighter, 28 mm tyres max | Lighter still, Trek lifetime warranty on the frame |
The key point: at this level of the range, the weight difference with Alpha 300 comes down to tube design and mounts, not to a difference in quality. In return, Alpha 100 accepts winter equipment, which the Émonda ALR doesn't cater for.
In a bunch, shifting precision matters: the 11-speed Tiagra avoids sudden jumps in cadence when the pace lifts, and the down-swing front derailleur shifts cleanly from the 34 to the 50. The tapered head tube and carbon fork keep your line steady when riding wheel to wheel.
Club rides from Béziers often head out towards Puisserguier and Quarante before climbing up to the ridges of Faugères: they mix brisk turns on the front with short climbs, where the 34x36 saves the end of the ride. For extra zip, a lighter wheelset remains the most effective upgrade, and we can guide you in your choice.
| Model | Material | Drivetrain | Wheels | Weight (size) |
| Domane AL 2 | Alpha 100 | Shimano Claris 2x8 | Paradigm 23 alloy | 10.35 kg (56) |
| Domane AL 4 | Alpha 100 | Shimano Tiagra 2x11 | Paradigm 23 alloy | 10.10 kg (56) |
| Domane AL 5 | Alpha 100 | Shimano 105 2x12 mechanical | Paradigm 23 alloy | 9.80 kg (56) |
| Domane SL 5 Gen 5 | OCLV 500 carbon | Shimano 105 mechanical | Aluminium | 8.84 kg (ML) |
Our take: for group rides, the AL 4 is enough to keep up; if your club rides fast and climbs a lot, the 300 g saving and 12-speed 105 of the AL 5 make the difference.

LVR sizing advice If you are unsure, the smaller size gives livelier steering, the larger one more stability on long descents. Cranks, handlebar and stem follow the size.

| Keeping up with a club group? | Yes for intermediate groups; the 11-speed drivetrain helps when the pace lifts. |
| Fitting lighter wheels? | Yes, standard thru axles: it is the most cost-effective upgrade. |
| Pedals included? | To be checked in store; we can recommend suitable clipless pedals. |
| Group riding in the rain? | Mudguards can be fitted; think of the riders behind you. |
