If I already have the shifter(s) and want to run my TT bike with a 1x11 Di2 setup am I correct in thinking I only need the following:
Rear Mech Junction Box Battery Wires
Is there any downside to buying older 11s stuff rather than the newest generation?
Yes, plus a charger.
That's reminded me I have Di2 TT cockpit stuff to sell..
Are you going to run a cable from RD all the way to the Junc A? Otherwise Junc B or something needed.
downside to buying older 11s stuff
Might need firmware update, battery life might be reduced, might be missing features but these issue for a TT bike unlikely to matter.
