Renthal 520 Pitch R4 SRS Gold Sealed Drive Chain


SKU: 520R4SRS-120 Category:

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. As the chain wears, conventional o-rings and x-rings lose 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 longer while also keeping dirt, water and other contaminants out.
