As mentioned above, Celos were made by colnago for Celo Europa which is a shop and possibly a distributor of some sort.. I forget. In anycase I have a 144 BCD super record style campagnolo Celo panographed chainring that fits record cranks... since you are running athena I guess you have a 135 BCD unless it is a mixed group and the cranks aren't athena... anyway should you be interested in this ring that appears barely used feel free to PM me. here is a pic. note how similar the C is to those on colnago pantoed rings
