CRs:
I'm trying to determine the threading of some freewheels, and I could use your assistance. I don't have a rear wheel to check these with:
1980 Regina Corsa, 6 speed, which has one circular groove on the back. There are no other markings. I think this is this English threaded, but there is no "FI" marking. Can you confirm if this is English threaded?
Shimano Dura-Ace model MF-7400, 7-speed. Were these made in English threading only, or other threadings as well?
Suntour Winner Pro 7 speed, 4-prong notched body. The top cone of the freewheel body is marked "DF VIA". Is this English threaded also?
Thanks in advance for your replies.
