Ted,

I know there were track specific rims in the mid-1970's but were these used exclusively. Did track riders use light road rims as well i.e. Fiamme Ergals, Mavic Record du Monde de l'Heures. Also, what was the evolution of the Campy one-piece shell track hub. Was there an early "no-Record" variant as in the road hubs? Weren't there versions with oiler holes and clips and versions without? I'm looking to purchase or build up some mid-1970's track wheels and I'm trying to stay period correct. BTW, if anyone has a nice, appropriate track wheelset, I have lots to trade. Sorry to ask such stupid questions but we had/have no tracks around here and I'm building up my first track bike.

Thanks as Always,

George Allen Lexington, Ky USA
