I bought an old Schwinn Paramount track bike on eBay a while back (1974). It came with what I thought were some unusual 1970's Campy hubs. They were high-flange road hubs with the rear threaded on one side for a freewheel. The hubs are drilled for 32 spokes, but between the stock spoke holes there were other, round, slightly larger holes drilled. I recently saw another old track bike on the BikeWorks website that had the same hubs and the caption referred to this as "Drillium Treatment" (see link). Anyone know what is up?

On a somewhat related question: If you watch "Breaking Away" they compete in the end in some sort of track event and their bikes are definitely single-speeds with freewheels...was this some sort of real event? Could this be why my Paramount track bike has hubs designed for a freewheel? The hubs are of the proper era for the frame and are laced to proper period "fiemme" rims, but the roadie/freewheel hub seems odd.
