It's all relative, though. The Ksyriums are definitely not considered aero by today's standards but they were one of the first to introduce fat bladed spokes, which, compared to the box rims with round spokes at the time, were thought to offer an aerodynamic benefit. They certainly caught a lot of cross wind. Today even the 30mm deep V alloy rims of the late 90s/early 00s aren't considered "aero" given how deep we've been able to go with carbon rims.
