In 8 years of riding with 9 speed Ultegra, I've used only Ultegra chains, aside from a brief try of a Wipperman stainless, which broke on me. I am now trying a SRAM PC991 chain. I like the Powerlink, but the chain seems way too noisy. I have a 39-53 double, a 12-27 cassette, and I use home brew 3:1 for lube. Has anyone else had this experience or is it just me? Does anyone have experience/advice about using the SRAM Powerlink on Shimano chains?
