Renthal twinring sprockets.

Each Twinring sprocket that leaves Renthal's engineering facilities are individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit

  • Inner ring of the Twinring is engineered from Ultralight 7075 T6 Aluminium which helps keep weight to a minimum
  • Outer ring is constructed from electroless nickel coated steel which ensures an ultra long service life
  • Mud grooves prevent build up of mud, helping to increase the working life of the sprocket
  • Renthal Front Sprockets
    These are precision CNC machined from case hardened and core refined 655M13 Nickel Chrome Molybdenum steel, with extremely tight tolerances for maximum longevity.

    Renthal R1 Works Chain features:

    • Renthal heavy duty chain complete with Split Link.
    • Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
    • Chamfered inner links to reduce the chance of chain derailment.
    • Extended bushings to reduce friction between outer and inner link plates, maximising power output.
    • Chromised bearing pins for excellent resistance to wear.
    • Gold colour side plates help 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 sprockets.
