Been considering doing a drive-side addition to my R8000 cranks (mid-compact 165mm) but I want the ability to swap to smaller chainrings (or go single) for a few events. I know the chainrings can be replaced by me or a mechanic no problem (assuming that I use R8000 or R9100 models). What I don’t know is if I there are any issues with switching to a non-Shimano chainring (e.g. Absolute Black or Wolftooth), if there are any size limitations (e.g. sub-compact), or if I can even go 1x.
Does anyone have experience with this?
