Featuring a \u003cstrong\u003e3\/32-inch chain pitch\u003c\/strong\u003e and a \u003cstrong\u003e2.5mm offset\u003c\/strong\u003e, this chainring ensures optimal chain alignment with the rear sprockets. The Boost system is the most advanced standard for modern electric bicycles, offering an increased rear axle width that improves stability and load distribution. The \u003cstrong\u003e15-tooth configuration\u003c\/strong\u003e provides an efficient gearing ratio for \u003cstrong\u003eelectric bicycles\u003c\/strong\u003e with Bosch mid-drive motors. With the lockring included in the package, the product is immediately ready for installation on any compatible system.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical specifications and compatibility\u003c\/h3\u003e\n\n\u003cp\u003eThis chainring is made with wear-resistant materials, essential for \u003cstrong\u003ee-bikes\u003c\/strong\u003e that require reliable components over time. The 2.5mm offset allows precise alignment with Boost cassettes, reducing lateral friction and improving power transmission efficiency. Compatibility with \u003cstrong\u003eBosch motors\u003c\/strong\u003e is total, regardless of the frame generation. The 3\/32 pitch is the universal standard for modern bicycle chains, ensuring interchangeability with components of equivalent quality. The inclusion of the lockring simplifies maintenance and future replacement of the component.\u003c\/p\u003e\n\n\u003ch3\u003eBenefits and performance of the Boost 148mm chainring\u003c\/h3\u003e\n\n\u003cp\u003eUsing a \u003cstrong\u003eBoost-specific chainring\u003c\/strong\u003e prevents premature wear and maintains optimal performance over time. The WA133 geometry has been developed to minimize lateral chain movement, a common issue in incorrect installations. For those using a \u003cstrong\u003eBosch e-bike\u003c\/strong\u003e, this chainring ensures perfect synchronization between the motor and drivetrain, improving overall energy efficiency. Periodic chainring replacement is recommended for high-use electric bicycles, as it is a component subject to natural wear.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eBrand: \u003cstrong\u003eFsa\u003c\/strong\u003e (reliable components for ebikes).\u003c\/li\u003e\n\u003cli\u003eNumber of teeth: 15T for Boost 148mm drivetrain.\u003c\/li\u003e\n\u003cli\u003eChain pitch: standard \u003cstrong\u003e3\/32 inches\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eOffset: 2.5mm for precise alignment.\u003c\/li\u003e\n\u003cli\u003eCompatibility: \u003cstrong\u003eBosch systems\u003c\/strong\u003e with Boost architecture.\u003c\/li\u003e\n\u003cli\u003eLockring: Included in the package.\u003c\/li\u003e\n\u003cli\u003eMaterial: Wear-resistant steel.\u003c\/li\u003e\n\u003cli\u003eApplication: \u003cstrong\u003eElectric bicycles\u003c\/strong\u003e and mountain ebikes.\u003c\/li\u003e\n\u003cli\u003eInstallation: Direct on 148mm Boost axles.\u003c\/li\u003e\n\u003cli\u003eMaintenance: Replacement recommended every 2000-3000 km.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fsa","offers":[{"title":"15 \/ Black","offer_id":54682339213658,"sku":"32700032029250","price":19.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/506463-379283837-img_8028.webp?v=1788345010","url":"https:\/\/www.all4cycling.com\/en\/products\/corona-fsa-ebike-wa133-bosch-3-32-offset-2-5mm-per-boost-148mm","provider":"All4cycling ","version":"1.0","type":"link"}
