Hi Again Alp,,,
I don't have any hard numbers on other APS bikes,,, as an educated guess ,,, maybe a few get down to Cd of .300 but I think most don't....
Cd of .400 is quite doable,,, I'll be glad give you advice on how to fine tune your aero package when you get to that point....
This is an area I know a little about...........
Best of Fortune to us all in the 2017 Season,,
