Featuring Zero ceramic hybrid radial bearings with Black-Oxide treatment, these pulleys provide a smooth, precise shifting experience and improved durability. Made from 500 AF Delrin, a material with high tensile strength, stiffness, natural lubricity, and resistance to moisture, chemicals and UV, these pulleys provide a lightweight, low-friction solution that offers less resistance than aluminum or titanium. The upper pulley uses CN (tight clearance) bearings for maximum shifting accuracy, while the lower pulley uses C4 (looser clearance) bearings to allow chain movement. The Black-Oxide coated 52100 high-carbon chrome alloy and Silicon-Nitride ceramic balls provide excellent wear resistance and long service life. Designed for compatibility with most 11-speed Shimano derailleurs, these pulleys are proudly made in the USA and provide a durable, smooth and reliable upgrade for serious cyclists.","brand":"ENDURO BEARINGS","offers":[{"title":"Default Title","offer_id":47172015423807,"sku":"0810191012887","price":96.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0841\/3478\/9439\/files\/EB9081_01_5d73a6a9-ec9c-47fc-88de-8e5b6236ef76.jpg?v=1783157614","url":"https:\/\/tormino.com\/products\/enduro-derailleur-wielset-zero-ceramic-zwart","provider":"Tormino","version":"1.0","type":"link"}
