Need older small inner Campy chainring

12 Mar 2017 17:09

Hi: I am a first time visitor and am in need of a few parts for my early 1970's touring bike. (Double butted with Campy dropouts with chrome accents) I currently have a campy triple (slotted Record arms) with 52/42/36. I would love to find a smaller inner ring...30 or 32 tooth for my 65 year old legs to climb hills. I switched to a larger spread on my rear 5 gear cluster but still need more for comfortable touring. Not sure of the BDC, but it measures 2-5/16" or 58.6m between two adjacent bolts. The crank arms are threaded to receive the bolts for this chainring alone. Used campy ring would be great but also any leads to a different brand new replacement would work just fine. I run an old Campy Rally rear derailleur so I have plenty of chain movement.
Thanks for any leads. I live in the central USA.

Draw a line between 2 adjacent bolts, then another perpendicular to that line to the bolt opposite-that's BCD.

Some info here-

Found the crank and 100mm BCD..aren't going to find any CRs for that(small)
