Description

The Renthal R3 is one of our favorite chains…high strength, great price and fantastic looks!

Renthal R3-3 chains are specially developed utilizing Renthal’s SRS technology to increase the service life.

The special SRS is pre-loaded during assembly, creating a spring effect. As a chain wears, conventional O-rings and X-rings loosen their seal whereas the SRS has the inherent ability to regulate a constant sealing pressure against the side plates throughout the life of the chain.

This offers increased longevity, as the specially formulated grease remains encapsulated around the critical pin and bushing area longer whilst preventing ingress of dirt, water and other contaminants
