>>1090108I think we may be talking about different things.
You are probably talking about pursuit bikes, like the one in this picture. That's quite a bit different from an "aero" bike.
A pursuit bike is intended for a very specific, short duration type of velodrome racing in which it is super important to be able to get as low as possible to draft efficiently and to avoid letting other riders draft you efficiently. People that ride them on the street are idiots.
An "aero" bike would generally be one designed for riding in events where drafting is either prohibited or impossible (because there is nobody else on the course).
