Hey guys, a while back I bought an SRAM chain due to rave reviews and I was going to replace it when I broke my Shimano chain. It hasn't broken yet but it does give me shafty performance, so I was wondering is this causing some pain for my drive train? So should I replace it even if it isn't broken?

I see a lot of you out there replace it right away, but I don't know if that's preventative maintenance or just dislike of Shimano chains.

Thanks thanks thanks
