The new Super Record, Record and Chorus mechanical groups were unveiled in late May, followed shortly thereafter by a new Chorus EPS group. The basic details were provided, but pricing, weights and the finer points were missing, so we used our time at PressCamp to fill in the holes.
When Campy unveils a new technology, it’s generally spread around its products fairly quickly. Sometimes it shifts altogether. Case in point: With it’s introduction, Chorus EPS is now the only mid-level electronic group – Athena EPS is no more, but it did get a functional update for the mechanical group.
Chorus keeps the different wire plug design that Athena had, which means it’s not compatible with Record/Super Record EPS. The reason they initially had a different wiring structure was to save costs over the more intricate plug design on the higher end groups. It’s still IP67 waterproof and just as secure as what’s used on SR/R, just a different design that’s simpler and cheaper from a new supplier. There’s no word on whether they’ll adopt that design on Record/SR down the road, but it certainly makes sense that they’d incorporate it on the next iteration.
