{"product_id":"fiido-c21-rear-derailleur","title":"Fiido C21  Rear Derailleur","description":"\u003cp\u003eThis \u003cstrong\u003ereplacement rear derailleur\u003c\/strong\u003e is a direct-fit spare part designed specifically for the \u003cstrong\u003eFiido C21\u003c\/strong\u003e electric bike. The rear derailleur guides the chain across the rear cassette during gear changes, and a worn, bent or damaged unit is a common cause of poor shifting, chain skip and dropped chains. A fresh derailleur restores crisp, precise gear changes and smooth power delivery through the drivetrain — a real quality-of-life fix for anyone whose C21 has been shifting badly.\u003c\/p\u003e\n\u003cp\u003eBuilt to match the OEM specification for the Fiido C21 frame and rear cassette, the derailleur bolts on cleanly using the standard rear hanger and shifter cable, with no modification required. Correct cage length, spring tension and pulley setup ensure it works with the C21's factory shifter and cassette straight out of the box, and standard bike-workshop tools are all that's needed for installation and cable adjustment. A dependable service part for any Fiido C21 owner, home mechanic or workshop across Ireland and the wider EU.\u003c\/p\u003e\n\u003cp\u003eOrder yours today with \u003cstrong\u003eInner City Scooters\u003c\/strong\u003e Ireland — delivering across Ireland and the EU.\u003c\/p\u003e","brand":"Fiido","offers":[{"title":"Default Title","offer_id":59476871807301,"sku":null,"price":30.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0895\/0923\/2965\/files\/FiidoC21RearDerailleur.jpg?v=1790247166","url":"https:\/\/innercityscooters.com\/de\/products\/fiido-c21-rear-derailleur","provider":"Inner City Scooters","version":"1.0","type":"link"}
