I've been trying to get my rear shift action dialed in for the past month but nothing seems to be making any difference. I've trimmed the housing so that there are no stiffening wires protruding beyond the plastic sheath, and I've cleaned a re-lubed the shift cable. I've also had a shop guy look at it and despite his twenty minutes of effort there’s not much difference. I can either tune the rear derailleur for the smaller cogs or the larger cogs but it will not shift through the entire rear cassette without going into constant ghost shifting at either the smaller or larger cog regions. It seems as if my shifter isn't moving the derailleur sufficiently far with each click. For example, if I set my rear derailleur so that it is dialed in on the smallest cog, I can see that with each shift to a larger cog, the derailleur tends to get closer and closer to the previous cog until it begins to ghost shift down to the previous smaller cog. Is there anyway to increase the amount which the derailleur moves on each indexed shift or is that a non-adjustable factor on XTR components? Any help or suggestions would be welcome.
