{"product_id":"renthal-twinring-rear-sprocket-524","title":"Renthal Twinring Rear Sprocket 520","description":"\u003cp\u003eThe Renthal Twinring™ rear sprocket offers the best of both worlds: lightweight performance and exceptional durability. Engineered for demanding riders, this sprocket is designed to withstand the rigors of off-road and racing conditions, providing superior longevity compared to traditional aluminum sprockets.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Renthal Twinring™ rear sprocket utilizes a unique two-piece design. The inner ring is manufactured from Renthal's high-strength Ultralight™ 7075 T-6 aluminum, the same material used in their standard sprockets, ensuring minimal weight and maximum power transfer. The outer ring is constructed from electro-less nickel-coated steel, providing ultimate durability and resistance to wear. The outer ring is carefully designed with minimal material to maintain a light weight. The two rings are permanently bonded using an interference fit process where the outer ring is expanded at 200°C before being fitted over the inner ring, with a wave pattern ensuring a secure bond for the life of the sprocket. Flat socket head screws add further strength, particularly during side impacts, and prevent contact with the chain guide. Self-cleaning mud grooves between each tooth prevent dirt build-up, reducing chainwheel wear and maintaining optimal performance.  Expect approximately three times the lifespan of a standard all-aluminum sprocket, with a weight significantly less than an all-steel equivalent.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003eInner ring crafted from high-strength Ultralight™ 7075 T-6 aluminum for weight savings.\u003c\/li\u003e\n \u003cli\u003eElectro-less nickel-coated steel outer ring maximizes durability and wear resistance.\u003c\/li\u003e\n \u003cli\u003eInterference fit with wave pattern creates a permanent bond between the inner and outer rings.\u003c\/li\u003e\n \u003cli\u003eFlat socket head screws enhance strength and prevent chain guide interference.\u003c\/li\u003e\n \u003cli\u003eSelf-cleaning mud grooves minimize dirt build-up and chain wear.\u003c\/li\u003e\n \u003cli\u003eOffers 3x the lifespan of aluminum sprockets, lighter than steel.\u003c\/li\u003e\n \u003cli\u003eDesigned for optimal power transfer and long-lasting performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003eBrand: Renthal\u003c\/li\u003e\n \u003cli\u003eProduct Name: Sprocket\u003c\/li\u003e\n \u003cli\u003eMounting Position: Rear\u003c\/li\u003e\n \u003cli\u003eChain Size: 520\u003c\/li\u003e\n \u003cli\u003eTooth Count: 48\u003c\/li\u003e\n \u003cli\u003eMaterial: 7075-T6 Aluminum \u0026amp; Nickel-Coated Steel\u003c\/li\u003e\n \u003cli\u003eType: Drive\u003c\/li\u003e\n \u003cli\u003eColor\/Finish: Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eNo specific requirements or limitations noted.\u003c\/p\u003e","brand":"Renthal","offers":[{"title":"Default Title","offer_id":53705111535946,"sku":"12100815","price":597.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/dd3d6aa3375f8745f04f5fd450f78e8b.webp?v=1767468339","url":"https:\/\/partsdenmark.pl\/products\/renthal-twinring-rear-sprocket-524","provider":"Parts Denmark","version":"1.0","type":"link"}
