This was my second PC-1 chain, I typically replace once a year for my fixed gear track bike . My LBS did not have them in stock, so I bought it here and had them install it. Did not ride the bike till Friday afterwork and was extremely noisy with every hard peddle effort , just annoying clacky noise ! No lube or anything could remedy the issue. Went to another bike shop that had the KMC brand and that solved the problem ! quiet just the way its supposed to be. had to bite the bullet and buy this chain. SRAM quality for this PC-1 model must have decreased or got a poorly built chain ,sloppy and noisy. And also own another bike with a SRAM Build its just fine . I will choose KMC next time I need a fixed gear chain or better.
