2024 Polygon Helios A7X road bike review: Aero on a budget - Escape Collective

Oct 2023 · Dave Rome

An incredibly well-priced performance-orientated aero road bike sold directly to consumers.

Highs
  • Incredible value

  • Well-mannered ride

  • Quick yet balanced handling

  • Shimano 105 Di2 group

  • Did I mention the incredible value?

Lows
  • Long reach isn’t for all

  • Adjusting stem height is tricky

  • Bars are real wide for an aero bike

  • No affordable option to change the handlebar

  • Tight tyre fit on rims

  • Out-of-box build could use a mechanic

  • Bartape.
