• 12 speed charger is just a wire too so way more convenient to carry than the old 11 speed block

  • Interesting. I want to get a Di2 GRX groupset for the grrl's (:-*) new gravel bike. I was going to get 11spd because that's what I have on pretty much everything else but is there any other improvements? Actually do they do 12s GRX Di2 bits? Really need to get googling again.

    Can the 12s charger work with 11s stuff? Or will we need to carry 2 chargers?

  • My 12spd Ultegra groupset arrived this morning and I’m pleased by how small the charger is.

    Does this mean it can be charged from a power bank? Or only from mains?
