Sub 0.180m^2 is the exception rather than the rule. We've got riders under that in AeroCoach sessions before but for top UK time triallists you're looking at 0.190-0.215m^2 depending on size. Anything over 0.215m^2 and you're not going to perform at a National level, and the higher end of that range requires big power. Considering that Crr is ~.005 on the best roads you use, that means that the benefit from traffic must be substantial in some cases. >10% CdA reduction. Thoughts?
Yes, especially on some courses (eg. V718) where the tree and building line is very high so any passing traffic is in largely still air.
