Because of my handicap (lost my right arm) I am interested in the DI2 system on a moutain handlebar (cfr the cory_rosene_di2_mountain_bike_100) . Can you tell me if you can connect the functionbuttons directly to the junction SM-EW79A-E independent the kind of the breakshifters (in others words do you need breakshifters to use the DI2 system?.
Is it maybe possible to send me the details about how to do this.
I thank you very much and hope you can give me the solution for my problem.
Ivan from Belgium.
