My chain is used and abused. I can't find what the length is supposed to be for a new one, and I don't know really what is good and bad. Any opinions are greatly appreciated.
The chain that came with your bike is 108 links, with a 13 tooth front and 47 tooth rear sprockets.
I'd stay with a O-ring chain, and use steel sprockets for maximum longevity.
Hope this helps.
