Specialized Aethos 2 review: Older, less cool, but I think it’s probably better than the old one

Mar 2026

Slightly tweaked geometry and bigger tyre clearances make it a more accessible bike for those who just want a road bike without worrying about aero

Highs
  • Geometry that's more rideable for more people

  • Handling is still very good

  • Extremely pretty

Lows
  • Slightly over-geared

  • Can't spec your cockpit of choice

  • Tyres too narrow for what it is good for

  • 35mm tyre clearance

  • Front-end integration

  • Still very light

Lows
  • Expensive in S-Works guise

  • Non-aero

  • Limited range depth

Oct 2025 · Ronan Mc Laughlin
