This is not a message with a hidden agenda requesting memberships, just an honest coment:

If I were not a paying member of this message board, I would become one right after reading a thread like this one.

A skipping chain on a traffic light, damaged chainring, blunt force facial trauma, the list goes on...

How much does it cost to avoid all of that!!!

Thank you for sharing ( both the issue in details as well as the solutions presented)
