Self-Regulating Seal (SRS) Technology Renthal R3 chains are 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.
  • Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
  • Nitrile Self Regulating Seals (SRS) retail a special vacuum injected grease around the critical pin and bush area, which extends the life of the chain.
  • High carbon alloy steel bearing pins for excellent prolonged resistance to wear, for both road and off road riding conditions.
  • Special finish: Gold coloured side plates and copper rollers prevent corrosion.
  • Most perfectly matched chain for Renthal Chainwheels allowing maximum power at the rear wheel. This also extends the life of both the chain and Chainwheels.
