Product Details
Universal R4 Chain Link by Renthal®. Renthal R4 Chain: Ultimate durability and performance. Renthal's R4 SRS Road chain is a specially developed sealed ring chain using 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.
