Renthal Twinring™ Rear Sprocket - 52 Tooth - Orange (Part Number 2240-520-52GPOR)

The Renthal Twinring™ Rear Sprocket features a high-strength Ultralight™ 7075 T-6 aluminum inner ring, providing exceptional durability and lightweight performance. The outer ring is crafted from electro-less nickel coated steel, offering ultimate resistance to wear and corrosion, making it ideal for demanding riding conditions. Designed with minimal material to reduce weight, the sprocket ensures optimal power transfer while maintaining strength for long-lasting use. The outer steel ring is expanded at 200°C and then fitted over the aluminum core using an interference fit, complemented by a wave pattern that guarantees a permanent bond for the lifespan of the chainwheel. This construction not only enhances durability but also prevents loosening or failure during intense riding sessions. Flat socket head screws are incorporated to add extra strength during side impacts and to eliminate contact with the chain guide, ensuring smooth operation and minimizing wear. Self-cleaning mud grooves between each tooth help prevent dirt buildup, reducing chainwheel wear and weight, which translates to improved performance and longevity. This sprocket is engineered to outlast standard all-aluminum options by three times, yet remains significantly lighter than traditional all-steel sprockets. Whether for motocross, enduro, or trail riding, the Renthal Twinring™ Rear Sprocket offers a perfect balance of strength, weight savings, and durability, making it a reliable choice for demanding riders seeking high performance and long-term reliability.
