from bicycling's preview of athena eps
New Wiring Components
The most significant difference is that Athena 11 EPS uses different wiring connectors. This is likely an attempt to prevent bike companies or riders from mixing and matching Athena with Record or Super Record. Campagnolo insists that the new connectors came into play because the company switched to a different supplier. The change, the company says, was made in order improve the quality of the products, and notes that forthcoming iterations of Record and Super Record will likely use the same connectors.

why does campy always introduce products 80% developed.
Although the Super Record, Record and Athena power units are the same, the Record’s level wiring harness is incompatible with Athena’s. A different configuration, polarisation and slightly thicker wires mean that Record and Super Record components can’t be mixed with Athena.
Was this incompatibility just a business decision to prevent people from saving money on come components by using Athena instead of Record or Super Record?
