IIRC the S-works frames are offset sizing, so a Medium is a 53cm vs. a 54cm in the Regular Roubaix like my 2019 Expert. I don't think the S-works are fitted with the Hover bar, either. at least not when I was in the market. So the smaller frame and lower effective stack height negated the purpose of the Roubaix for me, which was a more comfortable position than my Focus Izalco and still plenty fast. I did go from 16.8lb Izalco to 18.4lb Roubaix with carbon C38 disc wheels and Di2.. but the comfort tradeoff was more than worth it for me.
