This design enhances overall drivetrain compatibility while improving shifting efficiency and reliability.\u003c\/p\u003e\n\u003cp\u003eCombined with KMC’s GO innovative wax-based formula and a specialized wax treatment process, the chain delivers low-friction performance straight out of the box. This treatment significantly improves pedaling efficiency while doubling durability compared to conventional lubrication methods. Unlike oil-lubricated chains, wax-treated chains resist dirt and debris adhesion, reducing abrasive wear, simplifying maintenance, and extending the service life of both the chain and the entire drivetrain—ultimately lowering long-term maintenance costs.\u003c\/p\u003e","brand":"Royal BIcycle","offers":[{"title":"Default Title","offer_id":47359122931889,"sku":null,"price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0452\/4366\/2502\/files\/12s-__XFlat-PP.jpg?v=1780418829","url":"https:\/\/2ndbikeshop.com\/products\/x-flat-waxed-chain-12-and-13-speed","provider":"2ndbike Shop","version":"1.0","type":"link"}
