The Specialized Aethos Expert all-road bike in review

Aug 2022 · By

Our test team’s expectations of the Specialized Aethos Expert were very high. After all, the Specialized S-Works Aethos won our previous road bike group test by a large margin, albeit with a few upgrades. We put the stock Expert model featuring ULTEGRA Di2 components and a classic two-piece cockpit to the test to see if this model can fare just as well as an all-road bike, comparing it to six of this year’s best all-road models.

Highs
  • First-class handling

  • Quick acceleration

  • Pleasant level of vibration damping

  • Lots of all-round potential with the right upgrades

Lows
  • Tires are too skinny and offer limited reserves

  • Lack of integration

  • Understated looks

Specialized Aethos Comp review: More affordable, more weight, still magical - CyclingTips

Aug 2021 · James Huang

Even an extra 100 g and heavy parts can’t dull this frame's luster.

Highs
  • Superb chassis efficiency and handling, excellent ride quality, generous tire clearance, classically understated aesthetics, headache-free cable routing, proprietary (almost) nothing, SRAM Rival AXS works just as well as Red and Force.

Lows
  • Heavier than some might like, mediocre (and poorly built) wheelset, almost impossible to get.
