Renthal SRSβ’ Road and Road Race chain is a specially developed sealed ring chain utilizing Renthalβs Self Regulating Seal (SRS) technology to increase the service life. The special SRS ring is pre-loaded during assembly creating a spring effect. As the chain wears, conventional o-rings and x-rings loose their seal, however the SRS ring has the ability to unload itself during use keeping a tighter seal against the side plates. This offers increased longevity as the specially formulated grease remains trapped around the critical pin and bushing area while also keeping dirt, water and other contaminants out.
