I have a Regina Oro chain that is in good used condition that I have recently installed on one of my bikes. It is making a very annoying squeaking noise as it passes through the derailleur pulleys. I first thought it might be the pulleys and so I replaced them with some NOS pulleys. I have lubed it thoroughly with Pro Link. I have checked for stiff/sticking links.[None] I wish it were screaming loud noises. Then I would simply replace it. It's just this ANNOYING squeak when several links pass through the derailleur pulleys.
Help ! ! !
