2024 Trek Domane AL 2 Gen 4 review: Budget all-road

2024 Trek Domane AL 2 Gen 4 review: Budget all-road

An impressively versatile and previously-loved bike now held back by a pursuit of aesthetic-led design.

As a tech editor, I’m often more excited to test entry-level bikes than those with sky-high prices. Sure, a 7 kg superbike built with scrap from a space program (not really) is a hoot to ride, but it’s the balance of budget and function that intrigues me so much more about the lower end. 

Here, the assumption is often that those new to cycling will start with such a lower-cost bike. These bikes can make or break the future growth of cycling, and my hope is that the person buying such a bike has a positive experience that encourages them to stick around the sport we love so much.  

That’s where the Trek Domane AL comes in. I tested the previous iteration (released for 2021) and found it to be one of the best entry-level road bikes available. It offered a welcoming fit and confident handling without feeling dull. It provided ample tyre clearance to be used as either a road bike or light gravel bike. It was simple to keep well-tuned. Most importantly, it was an entry-level bike that I truly enjoyed riding. 

And that brings us to the latest iteration of Trek’s best-selling road bike. On paper, the new fourth-generation Domane Al retains a lot of what I liked in its predecessor, but it, of course, introduces a few new twists to the proven recipe. This is a solid bike, but as you’ll read, it fails to impress like the previous version. 

The short of it: Trek's most budget road bike, revamped, and still with class-leading tyre clearance.

Good stuff: Room for 40 mm tyres has this one ready for the gravel-curious. Solid build kit and frame will shrug off loaded commuting and mixed surfaces. Ready for fenders and a rack. Welcoming geometry and comfortable touch points.

Bad stuff: Disc brakes make for a heavy bike, and the mechanical disc brakes here aren't stellar. Heavy wheels and tyres make the bike feel more sluggish than it wants to be. Through-headset cable routing makes no sense on a bike with mechanical gears and brakes. Ultimately cheap gearing and brakes for a bike that, while Trek's entry-level, isn't as affordable as it should be.

The new Domane Al explained 

In its modern form, the Domane Al is a dropbar bike that blurs the line between being an endurance road and an all-road bike - the latter being a category of bike that is designed with the versatility to split its time across tarmac and well-kept gravel roads. And with official room to easily clear 38 mm tyres (I comfortably fit measured 41 mm rubber in my sample), it certainly has the tyre clearance to go off-road. Still, look to the gearing and geometry, and it’s clear Trek still intends this one first and foremost for those wanting a road bike (get a gravel bike if your ambitions are predominately focused on riding off-road).
