I used this on my single speed commuter. So far so good. It was cheap and I love the quick connector. We'll see how it holds up. In retrospect I would have gotten a kmc and will be for my 9speed drivetrain.
I have use a number of these chains on bikes with drive trains of 6, 7 and 8 speeds. All have performed quite well with no failures. Quiet and smooth performance even in the worst conditions. Be sure to use the price machine price since it lowers the price below the lower quality PC-830 chain price!
