Engineered for riders who demand both reliability and high-level performance, this sprocket is designed to withstand the rigors of high-powered race machinery while maintaining a lightweight profile.\n\nThe Supersprox steel rear sprocket features a CAD-designed, laser-cut construction that prioritizes durability. By incorporating an extra-thick tooth profile, this sprocket ensures better engagement with your drive chain and significantly longer component life compared to standard alternatives. The lightened core design successfully reduces rotating mass by as much as 20 percent, allowing for improved acceleration and handling.\n\n### Advanced Tri-Zinc Coating Technology\n\nThis sprocket utilizes Supersprox's signature Tri-Zinc coating technology, which applies three distinct layers to ensure peak performance and longevity:\n\n- Corrosion Protection: A base coat of silver and nickel provides a robust barrier against rust and environmental elements.\n\n- Black Passivation: This intermediate layer fills micro-pores in the steel surface, preventing abrasive road debris and grit from lodging in the drivetrain.\n\n- Slick Finish: The final top coat provides a smooth surface that keeps the sprocket clean and maintains its striking black appearance over time.\n\n### Key Features\n\n- Durable Steel Construction: Built to handle the stress of high-performance off-road and racing applications.\n\n- Optimized Tooth Profile: Extra-thick teeth provide superior contact with the chain for extended longevity.\n\n- Lightweight Design: Precision engineering reduces rotating mass by up to 20 percent without sacrificing strength.\n\n- Weather Resistant: Tri-Zinc plating offers an exceptional defense against corrosion and debris buildup.\n\n- Standard Pitch: Designed to integrate seamlessly with your existing drive components.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/beta-rr-2t-amp-4t-250-300-350-400-450-498-2013-2023-black-49-tooth-sprocket","buyOneNow":null,"basketWithThis":null}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
