Renthal Twinring™ Rear Sprocket - 50 Tooth - Blue (Part #2240-520-50GPBU)

The Renthal Twinring™ Rear Sprocket, part number 2240-520-50GPBU, is engineered for high performance and durability in off-road and motocross applications. Crafted from high-strength Ultralight™ 7075 T-6 aluminum for the inner ring, this sprocket offers exceptional strength while maintaining a lightweight profile. The outer ring is constructed from electro-less nickel-coated steel, providing superior durability and resistance to wear in demanding riding conditions. The design incorporates an interference fit at 200°C, with the outer ring expanded and fitted over the inner, ensuring a permanent bond through a wave pattern that withstands rigorous impacts and prolonged use. Flat socket head screws further enhance the sprocket’s integrity by providing additional strength during side impacts and preventing contact with the chain guide, which helps reduce wear and potential damage.
Self-cleaning mud grooves are strategically placed between each tooth, facilitating dirt and debris shedding to prevent buildup, which extends sprocket life and maintains smooth operation. This design allows the Twinring™ to outlast standard all-aluminum sprockets by up to three times, offering a significant increase in longevity. Despite its durability, the sprocket is noticeably lighter than traditional all-steel rear sprockets, making it an excellent choice for riders seeking a balance of strength and weight savings. Whether you're racing or riding in tough conditions, the Renthal Twinring™ Rear Sprocket provides reliable performance, enhanced durability, and a sleek blue finish that complements your bike’s aesthetics.
