PSA: Cervélo S5 2020 slower following groupset upgrade

Just passing on the link to what @Eric_Schlange_ZwftIn has reported at Zwift Insider today:
The skinny: what was the fastest frame on the flat is no longer, due to a groupset configuration. Can’t call it a bug.
For the moment, the Specialized Venge S-Works seems to be back to being the fastest on the flat. Check out Eric’s data as linked to in the article for more details.
