I've been wondering how this odd mixed system evolved. The diameter is a metric dimension (9 or 10 mm) yet the number of pitches is in a now obsolete British dimension (British Standard Cycle). I know Zeus used this system; did other non-Japanese Campy clones? Do current Campy hubs still use this, or have they standardized to a straight metric/ISO for axles and cones?
