The outer ring is crafted from electro-less nickel-coated steel, offering increased resistance to wear and corrosion while maintaining a minimal material design to keep overall weight low. The manufacturing process involves expanding the outer ring at 200°C and fitting it over the inner, creating an interference fit combined with a wave pattern that ensures a permanent bond for the sprocket's lifespan. This advanced construction enhances strength and longevity, making it ideal for high-impact applications.\u003cbr\u003eThe sprocket includes flat socket head screws that add extra strength during side impacts and prevent contact with the chain guide, reducing potential damage. Self-cleaning mud grooves between each tooth help prevent dirt buildup, which decreases wear and maintains optimal chain engagement. The design ensures the sprocket outlasts standard all-aluminum alternatives by three times while remaining significantly lighter than traditional steel sprockets, delivering a perfect balance of durability and weight savings for aggressive riding and racing scenarios.\u003cbr\u003eOverall, the Renthal Twinring™ Rear Sprocket offers a robust, lightweight, and maintenance-friendly solution for riders seeking maximum performance and longevity from their drivetrain components. Its innovative construction and high-quality materials make it a reliable choice for off-road, motocross, and enduro applications, ensuring your bike performs at its best over extended use.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eInner ring made from high-strength Ultralight™ 7075 T-6 aluminum for durability and weight savings\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOuter ring constructed from electro-less nickel-coated steel for enhanced wear resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInterference fit with wave pattern provides a permanent, secure bond\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFlat socket head screws increase strength and prevent contact with chain guide\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSelf-cleaning mud grooves between teeth reduce dirt buildup and wear\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eThree times longer lifespan than standard all-aluminum sprockets\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLighter than traditional steel sprockets for improved performance\u003c\/li\u003e\u003c\/ul\u003e","brand":"RENTHAL","offers":[{"title":"Default Title","offer_id":45191538737347,"sku":"12100252","price":142.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/184293.png?v=1779584329","url":"https:\/\/kellymotorsport.com\/products\/renthal-twinring%e2%84%a2-rear-sprocket-49-tooth-silver-part-number-2240-520-49gpsi","provider":"Kelly Motorsports","version":"1.0","type":"link"}
