I am a huge fan of SRAM chains on my geared bikes - but the PC-1 lasted about 6 weeks on my SS. The bushings disintegrated while on a ride. Replaced with the KMC 410 (what the bike came with, that lasted over a year...) and it was a huge improvement. Strange - I have heard that KMC makes Shimano's chains, and they don't hold up or shift for me well at all, except for Dura-Ace on the road. Just my experience - If you have 3/32" sprockets and cogs, hope the 870 works for you!
