Need a Campy BB, but what? redux
I had this thread in Mechanics earlier, but I think this might be a better place. I'm still confused.
I have an early Chorus crankset that I want to put on my Trek 610 to try a 172.5 arm length. I need a BB. I know it needs an English thread.
Speaking to Vecchio's, I'm told if it has an engraved shield logo, it is 1993 or earlier, and it needs a 111 mm BB with symmetrical ends. The Centaur BB and the AC-H 111 are examples of a good fit. Mine has a printed shield logo, but no word "Chorus" with the arm length. It also has the date code "41" engraved in a square. C-record BBs should also work in this case.
I also read on Branford's website that if it's before 1995 it can use those parts, but if it's later it needs a 102 mm BB. However, I don't know how to tell if it's from the 102 mm era or definitely in the 111 era? Can anyone help with this?
In the previous thread I posted a picture and, was told I have a first generation crankset. However, my parts do not have an engraved shield logo.
Can anyone help me straighten this out and decide what to buy?

1st generation chorus cranks did not have an engraved shield logo. It should have a silk screened or painted or whatever logo. 41 in a square as far as I can tell would be 1989. This is just a hunch of mine. It sounds like 1st gen. so yes you need the 111mm. I'll throw this out there... Leigh30's new bike has a 111mm athena in it which will work for you. As far as I know he does not need it, perhaps you should contact him. I know he needs a record BB (114.5mm english for super record cranks) trade?

Regarding a trade, I have a NR, not an SR, but it's NOS and would be worth a lot more than Leigh30's Athena.

Well the only true super record BB would have a titanium spindle, I guuuueeeeesss... so really you want a plane old record or nuovo record (i.e. thick cups) for super record cranks that you are actually riding, anyway... but yeah... I realize a record/nuovo record BB is worth more, especially nos, so I left it up to you to work something out if you wanted to.
