R3.3 O-Ring Chain: Specially developed utilising Renthal's SRS technology to increase the service life. The special SRS is pre-loaded during assembly, creating a spring effect. As a chain wears, conventional O-rings and X-rings loosen their seal, whereas the SRS has the inherent ability to regulate a constant sealing pressure against the side plates throughout the life of the chain. 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.

SRS Technology - 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.

Shot Peened - Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.

High Carbon Steel Pins - High carbon alloy steel bearing pins for excellent prolonged resistance to wear, for both road and off-road riding conditions - chains listed below are off-road chains. (see for road chains, which we are currently not importing - as at July 2017).

Special finish - gold coloured side plates and copper coloured rollers help prevent corrosion.

Pre-stretched - To help with an easy setup, each R3-3 chain is pre-stretched meaning adjustments are not required.

Perfect Match - Most perfectly matched chain for Renthal chainwheels (sprockets) allowing maximum power at the rear wheel. This also extends the life of both the chain and sprockets. Available in 520 pitch only, average tensile strength: R3-3 520 - 7420 lbf.
