PC 1071 HollowPin Chain

If you're looking to drop even more grams from your climb-happy 10-speed drivetrain, let us introduce you to SRAM's PC 1071 HollowPin Chain. This little item happens to be SRAM's entry-level chain with hollow pins, and it makes quite a first impression. As soon as it's introduced to your derailleurs and cogs, the PC 1071 saves around 20g as compared to similar chain models, but the heavy chamfering that goes into its construction means it still rides as smooth as a heavier chain, and SRAM's PowerLock technology ensures that installation is a simple, tool-free affair.
