I am running a 2x9 setup on my bike. I have a 3 speed XO gripshifter and a 2x10 FD. I sometimes get the chain to over shift going onto the big ring. I have the limit screws set where they need to be, but I need an extra click in the shifter so the chain doesn't rub. I have it pretty good now, but am still a little worried about the chain coming off. I know that the FD being a 10 speed makes no difference. Would a 3x9 FD be better to run 2x9 rather than a dedicated 2x FD. I have no issues with my 10 speed grip shift, but wonder if the 2 speed FD moves different than a 3 speed FD.
