Hi,
I am reaching out to the forum and the community. I recently aquired a 1970’s Centurion road bicycle that has a Suntour groupo. I had a issue not being able to take off one of the pulley bolts only to find out that it was stripped. I tried everything under the sun to get it off and no success. So I would really like to know if anyone might have one for sale? Or another idea for recommendations to possibly replace the rear derailleur with something else. Suggestions and help welcome.

Thank you,
Jesse
