OK, this may be hopeless, but I'd like to buy an inner chainring for an early Record crankset, 151mm BCD. I currently have a 52/49 set-up, and my legs would be most grateful if I could lose the 49 in favor of something smaller. Probably can't hope to find the elusive 44, but a 45-47 would be nice. Used is fine; nearly worn out won't get it. Doesn't even have to be gen-u-wine Campy.
Please reply off list and include what portion of the national debt you'd like in return. I'd offer my first born, but he's already past his sell-by date.
