The current Synapse is positioned much closer to the SuperSix EVO Gen 5 than earlier generations, but Cannondale does not appear to publish a direct “same aero stats” match in the materials I found. The clearest overlap is that the Synapse takes its aero inspiration from the SuperSix EVO, while the latest SuperSix EVO is the fifth generation.

What that means

  • The new Synapse is not just an old endurance bike with aero shaping; it borrows design ideas from the SuperSix EVO.
  • The current SuperSix EVO lineup is Gen 5, introduced in 2026 coverage as the newest version.
  • Cannondale’s own Synapse vs. SuperSix material emphasizes geometry and intent differences, with the Synapse about 25 mm taller in stack for a more relaxed position.

Best match

If you’re asking which SuperSix EVO generation the current Synapse most closely aligns with aero-wise , the safest answer is: SuperSix EVO Gen 5.

Practical takeaway

In plain terms, the Synapse seems to use a lot of the modern aero language of the latest SuperSix EVO, but tuned for endurance comfort rather than race-bike aggression. So it’s less “same stats exactly” and more “same design era and aero philosophy”.

TL;DR: Current Synapse ≈ SuperSix EVO Gen 5 aero direction, not an exact one-to-one stat match.
