I'm replacing a rear shifter cable on my Ultegra 6700, and I can't figure out what I'm doing wrong. If I follow the directions from Shimano (PDF warning!) and click on the big lever such that it would put the chain on the largest cog, I can't get the cable through as an internal part moves into the cable way and blocks it. If I don't follow the directions, I can thread the cable through the shifter, but then ANOTHER part seems to block the plug on the end of the cable from entering fully into the shifter and engaging the rotating drum.
I've been working on this for about three hours and can't figure it out.
Dura Ace 7800 is SOOOO much easier to work with.
