Combining the best of both worlds, it utilizes a lightweight aluminum core with a robust steel outer ring. This design provides exceptional longevity without sacrificing weight.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Renthal Twinring™ rear sprocket is engineered for extreme durability and performance. The inner ring is machined from Renthal's high-strength Ultralight™ 7075 T-6 aluminum, ensuring minimal weight. The outer ring is constructed from electro-less nickel-coated steel, providing ultimate wear resistance. Designed with minimal material, the outer ring keeps weight down while maximizing strength. The outer ring is expanded at 200°C before being fitted over the inner ring. This interference fit, combined with a unique wave pattern, creates a permanent and incredibly strong bond that lasts the life of the sprocket. Flat socket head screws further enhance the chainwheel's strength, especially during side impacts, and prevent contact with the chain guide. Self-cleaning mud grooves between each tooth prevent dirt buildup, reduce chainwheel wear, and minimize weight. The Renthal Twinring™ sprocket lasts up to three times longer than a standard aluminum sprocket, while remaining significantly lighter than a comparable all-steel sprocket. Upgrade to the Renthal Twinring for the ultimate combination of lightweight performance and exceptional durability.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eInner ring made from high-strength Ultralight™ 7075 T-6 aluminum for reduced weight.\u003c\/li\u003e\n  \u003cli\u003eElectro-less nickel-coated steel outer ring for maximum durability and wear resistance.\u003c\/li\u003e\n  \u003cli\u003eInterference fit and wave pattern ensures a permanent bond between the inner and outer rings.\u003c\/li\u003e\n  \u003cli\u003eFlat socket head screws add extra strength and prevent chain guide interference.\u003c\/li\u003e\n  \u003cli\u003eSelf-cleaning mud grooves prevent dirt buildup and reduce wear.\u003c\/li\u003e\n  \u003cli\u003eLasts up to 3 times longer than standard aluminum sprockets.\u003c\/li\u003e\n  \u003cli\u003eLighter than all-steel rear sprockets, improving 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, Nickel-coated Steel\u003c\/li\u003e\n  \u003cli\u003eType: Drive\u003c\/li\u003e\n  \u003cli\u003eColor\/Finish: Green\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eNo additional hardware is included with this product.\u003c\/p\u003e","brand":"Renthal","offers":[{"title":"Default Title","offer_id":53705047900490,"sku":"12101140","price":143.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/d103f6f25a0adf15436ba57b99b484df.webp?v=1767467649","url":"https:\/\/partsdenmark.com\/fr\/products\/renthal-twinring-rear-sprocket-520-chain","provider":"Parts Denmark","version":"1.0","type":"link"}
