Except, of course, the hubs with aluminum splines. Then only the older Dura-ace 10-speed cassettes will fit, since the splines are deeper than the 8/9/10/11 speed hubs with steel or titanium hub bodies. The problem with aluminum hub bodies is that the aluminum deforms under load- Dura-ace 10-speed made the splines deeper so the hub deformed less, which pretty much obsoleted themselves. They switched to titanium shortly therafter.
