EK/PBR 420SR Chain Kit 12/51 - Ultra-Light Sprocket
Designed for small displacement bikes and urban use, this EK CHAIN kit combines a 420 SR series chain with an ultra-light aluminum sprocket. The SR series maintains its flexibility even after many hours of service: the links benefit from a specific heat treatment that increases wear resistance without sacrificing the necessary flexibility for proper drive.
