Renthal Twinring™ rear sprocket delivers long-lasting drivetrain performance with a lightweight hybrid construction for off-road riding. A 7075-T6 aluminum inner keeps rotating mass low, while the nickel-coated steel outer ring maximizes wear resistance.
Get the durability of steel without the weight penalty. The Renthal Twinring™ Rear Sprocket is engineered for riders who want maximum service life from their final drive while keeping the bike responsive. Its two-piece design uses a high-strength 7075-T6 aluminum inner ring for low weight, paired with an electro-less nickel coated steel outer ring for outstanding tooth wear resistance.
Built for real off-road conditions, the Twinring’s self-cleaning mud grooves help prevent dirt build-up between teeth, reducing premature wear in muddy or sandy environments. The outer ring is heat-expanded and interference-fitted over the inner ring, and the wave pattern helps ensure a permanent bond for the life of the sprocket. Flat socket head screws add strength during side impacts and help eliminate contact with the chain guide.
