i can get good shifts 99% of the time, but there always seems to be at least one missed shift per ride. the cable is tight and i have the limit screws for the large cog\small cog set properly. i assume the barrel adjuster needs to be fine tuned, but i'm just kinda stabbing around in the dark with it. any advice?
My device for remembering how to do this is to turn the top of the barrel adjuster in the direction that is shifting "slow".
So if it's rattling/delayed when going from small cogs to larger ones, turn counterclockwise (increase cable tension).
Also I usually shift into the smallest cog (least tension on the cable), make the adjustment, then go back to the "troublesome" cogs and test again. 1/4 turn increments, don't do anything drastic.
