New 2021 Domane AL Disc

Trek has launched a brand new Domane AL Disc, an aluminium version of its flagship endurance bike.

Unlike the current Domane AL, the new model is disc-only, although Trek appears to be keeping one rim brake model of the old bike at the entry-level. 

The new Domane AL Disc’s frame is made from Trek’s 200 Series Alpha aluminium and it gets internal cable routing, with the rear brake and gear cables/hoses emerging at the bottom bracket.

The geometry is pure endurance, with a 54cm bike having 374mm of reach and 575mm of stack.

2021 Domane AL: lots of mounts, lots of clearance

The Domane AL Disc features thru-axles front and rear, and mounts for mudguards (fenders), front and rear racks, three bottle cages and a bento box on the top tube, plus Trek’s own Blendr stem that accepts various accessories.

With 32mm tyres as standard and official clearance for 35s, the bike looks to have great potential as a winter trainer, commuter, light gravel bike or touring machine

The stock wheels are even tubeless-ready, although it looks like you’ll need to supply your own tubeless tyres

The first generation alloy Domane, the Domane ALR, featured the same IsoSpeed seat tube decoupler technology as its carbon counterpart, but the latest bike (the third generation, by our reckoning) sticks with a conventional frame.

Trek does refer to the new Domane AL’s fork as ‘IsoSpeed’, but it doesn’t make use of any unconventional squishy technology to add comfort, it’s simply designed for compliance.

In any case, the new bike has a lot going for it and it’s priced competitively, with builds starting at $1,049.99 / £800 for a Shimano Claris-equipped model.
