First off(so as not to get scolded) I tried searching and admittedly not I'm too adept at refining search results yet. (Also ADD/OCD/Mad! and plain short on patience)
Did a quick Google also but only saw front trim info... SO, quite simply: is there trim adjust for RD, and if so what does it do/when and how to use ?
Additionally, I noticed my FD trim adjust works great when moving from low 5 gears to high, but only on my small ring. No effect, and/or doesn't even seem to be needed, on large ring after my recent tune, which I myself got spot-on. Is this normal or does the FD trim have some useful purpose when riding on the large ring??? Thanks in advance!!!
