^^^ yes, agree. I do have the rings installed accordingly.
This post was provided by an aquaintance in another thread...
With mechanical shifts I to have found that TA rings are likely to over shift as you describe. I think that I have it adjusted in the stand and it works for multiple rides and then the chain will climb to the outside of the big ring. In my case it seems to usually happen as a result of a particularly forceful shift of the FD.
A series of very small incremental adjustments to the limit screw has so far always found a setting that does not derail, has no chain rub in the small cog, and still lifts the chain easily. This is on a Santana with a 113mm square taper BB which I would think places the small cassette cogs more outside the crank than your Calfee. The trial and error process does however leave chain marks on my nice polished daVinci crank arms.
^^^ seems to concur with what I am finding using the Di2 FD. In the scenario I described (inner rear cogs and upshifting to big ring), the FD appears to move outward more aggressively than when using the outer rear cogs (with Di2, the FD trim is automatically tied to the RD cog position). I have the FD limit screws set to the minimum needed to prevent chain rub, so going with other rings.
