What is the deal with the different color Chain O-rings? Hardness of O-ring? Which color is better? I need a new one, Mine is adjusted all the way.

Thanks, Grego

 

Unless you plan on racing, I'd just get a plain O-ring chain. You can get a gold one, and you may feel better about it not breaking, but that doesn't mean it won't.

Sledpartsguy on ebay has a good price, and is a good seller. Also, you may want to change the sprockets while you're at it.
