Good shifts, reasonable weight and good durability, together with the reusable master link that makes chain removal and installation a piece of cake. This newer version is indeed quieter running than the previous PC1090. I am definitely a Shimano fan for just about everything else, but really prefer the SRAM chains. I still have never broken one and I really like the drilled side plates for weight reduction. We have some very steep hills and I sometimes shift down under a lot of pedal pressure. These chains hold up and don't complain, even with that kind of abuse.
Was previously running a Dura Ace chain which was very quiet an shifted well. DA are just plain expensive. This chain meets the price point for value and a great chain as well. I've used them before and my only complaint is it's slightly louder on my Red drivetrain. Other than that it works perfectly.
This is a nice chain in term for performance for flat rides, light weigh and quiet. But won't last if you do frequent climbing. After about 2-12 months 700 miles, mine was so stretched and needed replaced. My previous KMC lasted over 2000 miles.
I originally used the DuraAce chain due to the noise of the earlier SRAM chains. When I could no longer get the DuraAce chain for my 10 speed I gave this a try. Nice change, very easy to install with no pins and runs quiet!
This chain shifts equally well with Shimano and as well as SRAM cassettes, and the master link is such a plus (no messing with Shimano installation pins). I've run thousands of miles with this chain and never missed a shift. It's dead quiet, too. Highly recommended if you want a light, versatile chain that consistently performs well.
