Upgrade durability without the weight penalty with the Renthal Twinring™ rear sprocket. A 7075-T6 aluminum inner ring paired with a nickel-coated steel outer ring delivers long service life and consistent drive performance.
Highlight the main advantage: The Renthal Twinring™ Rear Sprocket is built to give you the best of both worlds—light weight and exceptional longevity. By combining a high-strength 7075‑T6 aluminum inner ring with an electroless nickel‑coated steel outer ring, it delivers durability that can outlast a standard all‑aluminum sprocket by up to 3x while staying significantly lighter than an all‑steel option. It’s an ideal upgrade when you want reliable drive performance in mud, sand, and hard racing conditions.
How it improves your ride: Worn sprockets accelerate chain wear, reduce efficiency, and can cause inconsistent power delivery. The Twinring’s steel tooth ring resists hooking and abrasion, while the interference-fit construction and wave pattern create a permanent bond designed to last for the life of the chainwheel. Self-cleaning grooves between each tooth help prevent dirt buildup—keeping your drivetrain running smoother for longer with less maintenance downtime.
