Product Description

Maximize your final drive durability without adding unnecessary dead weight with the Renthal Twinring™ Rear Sprocket. Engineered for riders who demand longevity from their final drive components, this 50-tooth black sprocket combines a lightweight core with a hardened outer ring to withstand the harshest off-road environments.

Utilizing an innovative dual-material construction, the inner ring features high-strength Ultralight™ 7075 T-6 aluminum to reduce unsprung mass, while the electro-less nickel-coated steel outer ring offers ultimate wear resistance against high-torque loads and abrasive terrain.

Frequently Asked Questions

Q: What materials are used to construct this Twinring sprocket?
A: It uses an inner ring made of Ultralight 7075 T-6 aluminum paired with an outer ring made of electro-less nickel-coated steel.

Q: How long does a Twinring sprocket last compared to standard aluminum options?
A: It is designed to outlast a standard all-aluminum sprocket by up to 3 times while remaining much lighter than a full steel rear sprocket.

Expert Pro-Tip: When installing the Renthal Twinring sprocket, ensure the flat socket head screws are torqued evenly to specification. The high-interference thermal fit creates a permanent bond, so keeping your chain properly aligned and adjusted will maximize the lifespan of both the outer steel teeth and your drive chain.
