During travel, it is very important to remove the entire rear  derailleur with an Allen key to avoid damage or to even fit in travel bags. It  is also important to lubricate the bearings in your system to increase the  longevity of and make the most out of your system. Adding oil to the  lubrication points on the back of the cage plate lets the oil penetrate the  bearings for proper lubrication. With proper care and installation, your  CeramicSpeed OSPW will be a great addition to your fastest bike. \u003c\/p\u003e","brand":"CeramicSpeed","offers":[{"title":"Gold","offer_id":43509653045292,"sku":"106202","price":524.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-oversized-ceramic-coated-pulley-wheel-system-limited-gold-shimano-dura-ace-9100-6499639.jpg?v=1771301707","url":"https:\/\/ricycles.com\/products\/ceramicspeed-oversized-ceramic-coated-pulley-wheel-system-limited-gold-shimano-dura-ace-9100","provider":"RA Cycles","version":"1.0","type":"link"}
