• 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?

  • Yeah, I have a charger from my other bike with Di2. That's where I will steal the TT shifter from as well. And is there anything the new stuff will do that the older stuff won't?

    As far as I can see it's just Bluetooth and sequential shifting, but if it's 1x I wouldn't need that anyway.
