Does anyone know of service instructions on the web? I disassembled them as far as I dared and flushed what I could see with WD-40, but they're a lot more complex than the old 6-speed ones I used to whip apart in 5 minutes.
The indexed (RH) shifter isn't as positive as it used to be and shifting is suffering badly. It's a new rear mech and new Shimano cabling, so the sticky shifter must be to blame. I really need to get it apart properly.
