Have not seen any published aero data on American Classic wheels. I think most people tend to go with wheels that have been wind tunnel tested and proven.

In the past, American Classic had a wheel called the American Classic 58. These were wheels built with zipp 404 hubs using AC hubs. it was a budget aero wheel for those in the know.

However, AC has never been known for aero design. they make some nice aluminium rims but their Carbon rim designs are outdated and are in line for an update.

Thank you for the reply, prices seem pretty competitive with some of the more "budget friendly" aero wheels, but like I said you don't see them at races very often. On top of this, I have searched and not found much data. Your answer explains some of this.

Had a set of American Classic carbon wheels several years ago. They were V-shape instead of toroidal or U-shape (firecrest).
