Have a set of Ultegra 6600 SL shifters that I'd love to put to use, but encountered an oddity with the right hand (rear) outer shift lever. It appears the lever return goes too far and so as a result, it's out of alignment with the smaller inner lever. It doesn't impact the quality of the shift, but because of the over-rotation on the return, I can only shift 2 clicks with one "sweep" instead of the normal 3 clicks.
Nothing is gummed up and nothing appears obviously broken.
Here is example of issue:
Here is example of the shifter next to a normal one:
Nothing is offset when looking at it from the front.
if I further disassemble, it looks like the problem is the alignment of one of the metal rings that is attached to the lever. The top blue circle is the problem shifter (two "Tabs" not aligned"), the bottom blue circle is the properly functioning one (two tabs aligned):
Close up of the correct one:
I am not sure what to disassemble to fix the alignment, as everything that I could see be easily disassemlbed has been done so. Anyone encounter this before or have suggestions?
