It replaces the original cage and pulley assembly with a carbon structure, aluminium pulley wheels and fully ceramic bearings. The system is intended for riders looking to reduce drivetrain friction and upgrade the rear derailleur with a lighter, performance-oriented assembly rather than simply replacing worn standard pulley wheels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSmoother Chain Path.\u003c\/strong\u003e The oversized pulley layout reduces chain articulation as it passes through the rear derailleur, while the fully ceramic bearings are designed to minimise rotational resistance. The aluminium pulley wheels provide a rigid alternative to conventional plastic pulleys, and the carbon cage keeps the assembly lightweight while maintaining structural stiffness during shifting and sustained riding.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility is \u003c\/strong\u003e\u003cb\u003eSpecific.\u003c\/b\u003e This version is designed for Shimano Ultegra R8100\/R8150 and Dura-Ace R9200\/R9250 12-speed rear derailleurs. It is not intended for Shimano 11-speed systems or Shimano 105 Di2 12-speed. Nova Ride recommends fitting a new chain during installation and setting the chain length correctly for the oversized pulley arrangement. Cassette compatibility should also be checked before installation.\u003c\/p\u003e","brand":"Nova Ride","offers":[{"title":"Grey","offer_id":48031865176225,"sku":"3770017366662","price":23499.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/5869\/2257\/files\/ShopifyProducts_e846b27a-454f-4ffc-ac76-844100b40774.png?v=1791439071","url":"https:\/\/www.thebikeaffair.com\/products\/nova-ride-derailleur-pulley-for-shimano-ultegra-dura-ace-12-speed","provider":"The Bike Affair","version":"1.0","type":"link"}
