I'm currently in the process of tearing down my road bike to the bare frame. As part of this I will be taking many of the components apart to re-grease bearings, remove grime, and make any needed adjustments. I will also be replacing some of the mismatched components so that I'm riding a complete group.
I personally installed all of the components new, straight from the box to the bike. So I know that they are complete and installed correctly. Since there seems to be much confusion about some of these components on the interwebs. I hope this I can help clear up some of these issues with vintage Campagnolo Corsa Record and Chorus (circa 1986-1988) components.
If there is anything that you have questions about or would like pictures, let me know and I'll try to help.
