Sorry for all the questions but trying to work out the best option for a groupset for new frame. I'm likely to use a ultegra di1 groupset either 11 speed or 12 speed.
Has anyone used a GRX double chainset with a di2 front mech without issues for the extra 2.5mm?
Will 11 speed chainrings work with 12 speed chains?
I'm hoping that that should help me work out my best option
