My bike with GRX shifts very well, but needs frequent fiddling to keep it that way. While my di2 needs nothing.
Speaking of GRX, are any stock bikes out yet, available with Di2 GRX?
Also, I like some of the Giant bikes (endurance, gravel), but they don't seem to offer Di2 for any model of bike they sell. Why not?
