I know Campy's seatpost binder bolt is keyless (i.e., has no "tang" on the one half), but are there others as well? Every other vintage binder I've seen (Stronglight, Zeus, Sugino) had a tang. My Mercian's seatlug has no slot in the lug, so I took a cheapo Kalloy binder and ground the tang off with a Dremel. Ideally, however, I'd like something a tad nicer/more vintage.
