All of the SRAM chains are good. I asked SRAM once and was told that there is almost no difference in the models except for the special feature of that model. The 5x (58, 59) is black/silver. The 69 all silver, 89 heavy duty for off road, 99 has perforated sideplates for weight saving. The basics are identical. I use mostly PC-69 just because I like the all silver look better, but I have used 59s, too. The 58 should be fine with 3/32 sprockets. BTW, all multispeed chains are 3/32 inside width.
