I wanted to upgrade the stock KMC chain that came with my Giant Advanced Pro2. The drive train was very noisy in the smaller cogs on the cassette. I also purchase the chain tool and was able to do the replacement myself. What a difference! Shifting is crisper and the drive train is quite in the high and low gears. When it's on sale you can't beat it. Very pleased.
Another great product from SRAM. I use this on my 1x11 CX1 Super X Cross Bike and love it. No dropped chains, always crisp shifting! The CX1 1X11 is a game changer, it has plenty of range! I run a 11-32 in the back. No dropped chains in the past 2 years of CX racing is so fast!!!
My new bike came with a $100 KMC chain which didn't work well. Very noisy in the smaller cogs. Switched to this chain and the noise was gone. Love this chain will always use SRAM going forward. Someone else reported the same issue with a KMC chain and the 11-speed cassette like mine.
