This is is basically a complete Shimano Dura-Ace 9070 Di2 groupset minus the crank. Y'all have power meters so you don't need one anyway. Some of this is used, and some is brand new. I take good care of my equipment, so there are very few flaws and all are in working order. Your bike should be Di2 capable. If not, different parts may be needed to run the wires externally. I can help with that.
I'd like to sell it as a group before breaking it up. I'm asking $850 for everything. The package includes:
RD-9070 rear derailleur, used. A few marks from taking it on and off the trainer. No grind marks from the ground. 30T capacity on the right frame.
FD-9070 front derailleur, used. Normal inner cage wear. 16T capacity.
ST-9070 STI brake/shifters, used. No visible flaws.
BR-9000 caliper brakes, used. New Dura-Ace pads.
SM-EW-90A 3-port front junction box, new. This straps to your handlebar stem.
SM-JC-41 junction B box, new. This fits inside the frame.
SM-BCR2 battery charger and programming interface, new.
SM-BTR2 internal battery, used. This fits inside your seatpost.
SM-EWSD50 wires, new. (2) 350mm, (1) 300mm, (1) 650mm, (1) 700mm, (1) 1000mm. These connect everything.
