Review on High-performance Chain 116 Links CN-HG901-11: Perfect Fit for 11-Speeds Without End Pin by Aaron Stewart

I was skeptical of several previous reviews that reported receiving chains from low end models and mislabeling the packaging. This is the real deal and at the best price on the web with a quick link included. If you're using Shimano components, stick with their chain. I replaced the worn out Ultegra with a gold Knc and it was making a lot of noise. That should be there. From all the reviews I read it's as smooth as the 701 but more durable. Time will tell, but smooth shifting and quiet operation are already okay.
