I'm looking for the "Cover with tongue" which goes over the cable at the rear derailleur and prevents the cable from fraying. I've run the bike without it but the cable frays and fails prematurely.
The Ultegra 6800 and Dura Ace 9000 manuals list the part separately as Y5XX38000.
The 105 manual lists it as part of the "Cable Adjusting Bolt Unit" under part number Y5YE98030.
Either way, I have an immediate need for one and would like to order a half dozen to have on hand. All I can find is eBay and UK based sites.
They guys at Performance used to hook me up.
Anyone know of a US based online source?
