....SRAM has a master link that allows you to easily make or break your chain.....
Note : The SRAM PowerLink is NOT reusable like a standard master link . You can easily add one and if you need to break the chain it is the obvious choice to have its rivit driven out, but a new one is required each time.
How is the PowerLink not reusable? Not reusable, as in it's difficult to take apart, or not reusable, as in you're not supposed to take it apart? If it's the latter, I've never heard of that. That practically defeats the purpose of having the link. I've never had problems taking SRAM links apart and putting back together for the last 12 years I've been using them.
I'll admit the 10-speed chains are difficult to take apart after the 1st time, but after that no problems. No problems w/ 8 or 9 at any point.
If you don't know how to take them apart: you squeeze the plates together, and push the opposing ends of the link together, pushing the "rivit" through the larger hole on either side of the plates, allowing you to take it apart. (OK, it'd be easier to show you).
