Renthal's R4 SRS Road chain is a specially developed sealed ring chain utilizing Renthal's Self Regulating Seal (SRS) technology to increase the service life of the chain in road applications. The special SRS ring is pre-loaded during assembly creating a spring effect.
- Nitrile Self Regulating Seals (SRSTM) retain a special vacuum injected grease around the critical pin and bush area, which extends the life of the chain.
- SRS is pre-loaded during assembly, creating a spring effect. SRS has the ability to regulate sealing pressure against the side plates. 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.
- Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
- High carbon alloy steel bearing pins for excellent prolonged resistance to wear, for both road and off road riding conditions.
- Gold coloured side plates and copper coloured rollers help prevent corrosion.
- To help with an easy setup, each R3 chain is pre stretched meaning adjustments are not required.
