Only Altenbergers I've experience with are centerpulls on a heavy framed bike boom import called a Del Rimo or something like that. Put it together for my father in law and don't think he's ridden it much.
I like modern dual pivots, like them alot actually. On my otherwise Campy SR Basso I've put on a set of dp Records.
