Product Description

Get the ultimate combination of lightweight performance and unmatched longevity with the Renthal Twinring Rear Sprocket. Designed for high-performance off-road riders who demand maximum durability, this hybrid sprocket outlasts standard aluminum alternatives by three times while remaining much lighter than a full steel setup.

The inner ring is crafted from high-strength Ultralight 7075-T6 aluminum to reduce unsprung weight, while the outer ring features an electro-less nickel-coated steel construction for extreme wear resistance. The outer ring is expanded at 200°C and permanently bonded over the inner ring using a wave pattern and flat socket head screws for maximum impact strength.

Expert Pro-Tip

Expert Pro-Tip: Because the Twinring's outer steel ring offers exceptionally high wear resistance, always inspect your chain and front sprocket thoroughly during installation. Pairing a long-lasting Twinring with a heavily worn chain will cause premature wear on the chain rollers rather than the sprocket itself.
