Renthal Twinring™ Rear Sprocket - 48 Tooth - Orange (Part Number 2240-520-48GPOR)

The Renthal Twinring™ Rear Sprocket, part number 2240-520-48GPOR, offers a high-performance solution for off-road and motocross enthusiasts seeking durability and lightweight design. Crafted with an inner ring made from high-strength Ultralight™ 7075 T-6 aluminum, this sprocket combines strength and weight savings essential for competitive riding. The outer ring is constructed from electro-less nickel coated steel, providing exceptional durability and resistance to wear in demanding conditions. The manufacturing process involves expanding the steel outer ring at 200°C and fitting it over the aluminum inner ring with an interference fit, secured further by a wave pattern that guarantees a permanent bond for the sprocket’s lifespan. This innovative bonding method ensures reliability during intense riding sessions and minimizes the risk of failure. The flat socket head screws enhance the sprocket's structural integrity by resisting side impacts and preventing contact with chain guides, while self-cleaning mud grooves between each tooth effectively reduce dirt accumulation, wear, and weight. Designed to last three times longer than standard all-aluminum sprockets, the Renthal Twinring™ combines longevity with a substantial reduction in weight compared to all-steel options, making it an ideal choice for riders seeking performance and durability. Its vibrant orange finish not only adds a stylish touch but also improves visibility on the trail or track, ensuring your bike stands out. This sprocket's thoughtful design and high-quality materials deliver a reliable, long-lasting component that enhances drivetrain efficiency and overall bike performance in rugged riding environments.
