Di2 2nd junction box

fionamarsh2010

Im looking at using an internal battery with external mount (has 6 inputs)
1 for battery , 1 for junction a , 2 for front n rear mech.

Does anybody know if on 1 of the other ports you would be able to add a 3 port box to this so i can run a set of shifters on the bars just for the rear mech,ie sprinter shifters.

Thanks
Front n rear mech are the r8050 .

If your using ST-8050 shifters then your sprint shift buttons plug straight into the shifters with no need for a second box.
