Right now the shifting isn't that smooth. Just put on a new hanger as it was slightly bent. I'm looking for a smoother shifting experience with hopes this will improve my riding.
True, but not really.
A 10 speed 105 derailleur will work just fine on an 8speed cassette. It only does what the shifter tells it to do.
BTW, Poor shifting is often caused by gunked up cables or shifters.
