I have a set of 7-sp only, 1989 Chorus, I think, and a set that has the little lever on the side. I also have 2 blue inserts and 1 yellow insert.
What I don't have, is a set of instructions on how to mount them. I've mounted them two different ways so far, and can't get an index "click." They just swivel.
The Chorus has a matching RD/FD/Regina America freewheel, and I'd like to mount them right, as a 7-speed.
The other set, which has the little lever on the side, I'd like to mount as a 6-sp.
1-Is there a .pdf out there with the blow-up diagram for these?
2-Which insert is 6, which insert is 7?
3-Can I use the 6-sp with a Shimano 600 freewheel?
