I have a broken inner cage plate on my Shimano Ultegra RD-6700 GS rear derailleur. This replacement part # is Y5VG09300, and I can't find this part anywhere.
I'd really hate to throw out a perfectly good Ultegra level RD for want of 1 broken part.
Can somebody recommend a compatible replacement inner cage plate, or somewhere I can buy the correct one? Thanks!
