Renthal R4 Chain: Ultimate durability and performance
Renthal's R4 SRS Road Chain is a specially developed seal 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 integrity, whereas the SRS ring is designed to maintain itself during use, keeping a tighter seal against the side plates.
- SRS technology - the SRS ring technology enhances chain flexibility and offers smoother operation than standard o-ring chains, whilst also increasing durability
- Quality materials - all R4 SRS Road chains feature high alloy steel plates and pins, solid bushings and rollers, shot peened side plates for added strength and gold side plates
- Improved strength - special quad riveting process and thicker outer plates increases overall strength
- Pre-stretched - chains come pre-stretched from the factory so less adjustment is needed during initial break in
