Anyone have any idea if this will be compatible with the current 105-Ultegra-DA 10speed stuff?
I’d love to get my hands on the STI shifters with the new routing but don’t want to have to replace the whole groupset.
I would guess that the Ultegra 6700 series group will have the same compatibility as the Dura-Ace 7900 series group.
