Yes, plus an error on my part. Was going off memory and swore the rear cogs had Campy stamped on each I could not find any markings on either bike (still think the cogs on mens may be Campy, but the garage is dark and my eye sight isn't what it once was).
You are correct. As my memory is jogged, the cogs were separate from the freewheels could be swapped out but they sit on any freewheel. (Like I said it's been a long time since taking bikes and over 20 years since I played around assembling and disassembling.) I even have a cog puller in my tool kit. So much for "senior memory". LOL
Womens bike is MF Z012 Shimano Only cog marks are <20> <24> and so on.
Mens is Suntour AL
As mentioned Mens front rings are marked Campagnolo Woman's are Sun tour. I'll have to check parts box to see if I have Campy rings laying around. Guessing I would have swapped them on the green bike if I did..
