Converting Di2 9070 to Disc brakes

Hi all. I have an Open Up frame that I would like to move my Dura-ace 9070 drivetrain over to from my road bike. What is needed to convert to disc brakes? Will any di2 disc brake shifters work? Will any? I have been searching but couldn't find a solid answer. Thanks.

You might want to post this in "Bicycle Mechanics" sub-forum to get more responses. Or maybe a mod. could move it there.

You really only "need" to buy calipers themselves. TRP Spyre or Hy-RD. They will work with your existing rim-brake brifters....now they won't feel as good as hydraulics, and they are a little more needy WRT adjustment (you have to manually advance the pads)...but it is much cheaper than buying a $500+ set of brifters and brakes.

Now...if you want hydraulics, then yes, any of the Di2 hydraulic brifters can talk to your 9070 kit.

Thanks! The Spyres are a great idea!
