I’m swapping out my Ultegra 10speed di2 6770 for R9100 so I have a full E-TUBE set with front & rear mechs, battery, 5 & 3 port junction/charger port and road STI shifters. Should be available next week if anyone is interested.
It will not come with brake callipers (it came off an aero road bike so ) or charger unit I need it for my TT bike.
