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

Feb 2024 · Dave Rome

Trek’s most budget road bike, revamped, and still with class-leading tyre clearance.

Highs
  • 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.

Lows
  • 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.
