SRAM took the lightest and most durable chain they’ve ever made and made it lighter. With no compromises. Their HollowPin construction is lighter and stronger than a solid pin, and cutouts in the outer and inner plates drop 13g from the previous generation. This results in a lighter, faster, stronger and more durable chain.
