Hi, I am using a new RD and chain on my bike and set it up the normal way by setting stop limits, and removing "slack" from the shift cable and tightening the anchor bolt. In the stand, it shifts through all the gears great.
On the road, it shifts great and feels good in most gears...but a couple of gears give a "grindy/crunching" sensation when pedalling. No noise, just feeling through my feet that I haven't had before.
Does this have anything to do with excess tension on the shift cable? I always wondered if using the barrel adjuster really matters with friction shifting like it does for index...Can too much tension cause over-shifting of some cogs..well, maybe make it difficult for me to find the sweet spot?
