Hello,

I’m converting a racing bike from 66 to a 650b randonneur. It has fully campagnolo parts and I was thinking that it would be nice to keep it as far as possible like that.

I know that campagnolo nuovo record can be converted in to a longcage with a cage from rally. But would the same cage work on earlier record derailleur?

or are there some other longcage derailleurs from 66 or earlier?

I have a huret jubilee as a back up plan, but its bit too new…

thanks!
