Renthal Twinring™ Rear Sprocket 48 Tooth Black - Part Number 2240-520-48GPBK

The Renthal Twinring™ Rear Sprocket with 48 teeth combines durability and lightweight design for high-performance off-road riding. Crafted with an inner ring made from high-strength Ultralight™ 7075 T-6 aluminum, this sprocket offers exceptional strength while maintaining a low weight profile. The outer ring is constructed from electro-less nickel-coated steel, providing enhanced durability and resistance to wear. The manufacturing process involves expanding the outer ring at 200°C and fitting it over the inner ring with an interference fit, reinforced by a wave pattern, ensuring a permanent bond that lasts for the life of the chainwheel. This design not only guarantees longevity but also maintains structural integrity during intense riding conditions. Flat socket head screws add additional strength during side impacts and prevent contact with the chain guide, contributing to overall durability and smooth operation. Self-cleaning mud grooves between each tooth help prevent dirt buildup, reducing wear and keeping weight down for optimal performance. This sprocket is engineered to last up to three times longer than standard all-aluminum sprockets, offering an excellent balance between strength and weight. Ideal for riders seeking a reliable, long-lasting sprocket that withstands harsh environments while minimizing weight, the Renthal Twinring™ 48-tooth rear sprocket is a top choice for motocross, enduro, and trail riding applications.
