Re: Suggestion on what to do with the master link in your new kit!
Now that chain break gets a bad rap... I broke two of them before I figured out it was me not the breaker. You can not wind it to the end and put pressure on it. It just strips the threads.
I wouldn't even try it on a large chain though I broke one of them on a motor chain trying to force it out. I have one now and have used it several times on bicycle chains and it works great.
