EK/PBR 420SR Chain Kit 11/58 - Ultra-light Sprocket
Designed for urban use, this EK CHAIN 420SR chain kit combines the simplicity of a steel chain with the lightweight of an ultra-light aluminum sprocket. The SR series benefits from a specific heat treatment of the plates that preserves the flexibility of the chain even after long kilometers in the city and improves wear resistance without promising unverified performance.
Ideal for small displacement bikes and daily urban commutes, this kit is aimed at city riders looking for a lightweight and responsive transmission. It provides a robust foundation for regular maintenance: regular cleaning, lubrication, and tension checks remain essential to get the best out of the chain and sprocket.
