Combining lightweight design with robust construction, this sprocket is engineered to withstand the rigors of off-road and on-road riding, providing long-lasting reliability.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Renthal Twinring™ Rear Sprocket features a unique two-piece design. The inner ring is machined from Renthal's high-strength Ultralight™ 7075 T-6 aluminum, the same material used in their standard sprockets, ensuring minimal weight and maximum strength. The outer ring is made from electro-less nickel-coated steel, providing ultimate durability and wear resistance. This steel outer ring is carefully designed with minimal material to maintain a low overall weight. The outer ring is thermally fitted to the inner ring, creating a permanent and robust bond that can withstand extreme conditions. Flat socket head screws add additional strength, especially during side impacts, and prevent interference with the chain guide. Self-cleaning mud grooves between each tooth prevent dirt build-up, reducing chainwheel wear and weight. The Renthal Twinring™ sprocket offers up to three times the lifespan of a standard aluminum sprocket while remaining significantly lighter than an all-steel rear sprocket. Ideal for riders seeking a balance of weight savings and long-term durability.\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 reduced weight.\u003c\/li\u003e\n \u003cli\u003eElectro-less nickel-coated steel outer ring for exceptional durability and wear resistance.\u003c\/li\u003e\n \u003cli\u003eThermally fitted outer ring ensures a permanent and robust bond.\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, reducing wear and weight.\u003c\/li\u003e\n \u003cli\u003eOffers up to 3x the lifespan of standard aluminum sprockets.\u003c\/li\u003e\n \u003cli\u003eLighter than all-steel rear sprockets, improving overall 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: 50\u003c\/li\u003e\n \u003cli\u003eMaterial: 7075-T6 Aluminum \u0026amp; Nickel-coated Steel\u003c\/li\u003e\n \u003cli\u003eColor\/Finish: Black\u003c\/li\u003e\n \u003cli\u003eType: Drive\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":53705099084106,"sku":"12100805","price":143.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/3c1eb38c246504f704d00d776245600e.webp?v=1767468245","url":"https:\/\/partsdenmark.com\/it\/products\/renthal-twinring-rear-sprocket-520-50t-black","provider":"Parts Denmark","version":"1.0","type":"link"}
