Engineered for performance and longevity, this sprocket is a must-have for serious riders.\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. The outer ring is constructed from electro-less nickel-coated steel for maximum durability. Designed with the minimum amount of material to further reduce weight, the outer ring is expanded at 200°C and then fitted over the inner ring. This interference fit, combined with a wave pattern, creates a permanent bond that lasts the life of the sprocket. Flat socket head screws provide additional strength, especially during side impacts, and prevent contact with the chain guide. Self-cleaning mud grooves between each tooth prevent dirt buildup, reducing chainwheel wear and weight. The Renthal Twinring™ sprocket lasts up to three times longer than a standard all-aluminum sprocket, while remaining significantly lighter than an all-steel rear sprocket. Upgrade to a Renthal Twinring™ rear sprocket for improved performance and extended service life. This 520 chain size, 50-tooth sprocket is ideal for riders seeking maximum power transfer and 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 provides ultimate durability and wear resistance.\u003c\/li\u003e\n    \u003cli\u003eInterference fit and wave pattern ensure a permanent bond between the inner and outer rings.\u003c\/li\u003e\n    \u003cli\u003eFlat socket head screws add 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\u003eSignificantly lighter than all-steel sprockets, with superior longevity compared to all-aluminum sprockets.\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\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\u003eInstallation should be performed by a qualified mechanic.
