SRAM PC-1051 10-Speed Bike Chain

In SRAM's chain hierarchy, only the PC-1051 and PC-1091 chains are made with corrosion-resistant nickel plating on both the inner and outer links. What's the difference between this PC-1051 and their top of the line PC-1091 then? Where the 1091 has hollow pins, the 1051 uses solid, chrome hardened pins at the link pivots. Sure it's not quite as light, but you'll save enough money to build your wheels with alloy nipples instead. And from a performance standpoint, you'll be money ahead.SRAM has done some subtle reshaping of their outer plates to make their chains run quieter. This PC-1051 is made specifically for 10-speed drivetrains, and like its fancier hollow-pinned relatives, it mates perfectly with the tooth shaping and pickup/release points on SRAM's cassettes and chainrings for flawless shifting performance.You can install a PC-1051 chain without special tools thanks to SRAM's PowerLock connecting link. No other sub-6mm chain in the marketplace shares this feature.
