This was a great price for a high end chain to replace the one I've had for many years on my Giant TCR1 bicycle. Not many 9 speeds around much any more. So far it has been everything like the great original chain it has replaced.
I've had excellent results with the Shimano narrow chains for my 3x9-speed commuter over the years. These chains perform for extended mileage, I typically get 8000 miles for a drive train with Shimano chains during year-round commuting. I'd like it if they came with more than one connecting pin, or packaged together with a quick link, but those are available separately.
I bought the bike used with the chain already on the bike. I do not know how many miles it had on it when I got it. I have put 10,000 miles on the bike with the chain with routine cleaning with Simple Green and lubing with Purple Extreme with less than 34% wear indicated using chain measuring tool. I clean and lube every 400 miles or so and more often in wet riding conditions. Main use of the bike is road rides.
I highly recommend this chain.
