    R3 2017 Disc Di2 Upgrade

    One of my shifters has broken and thinking of using this as an excuse to upgrade to Di2. The only thing that puts me off is removing the BB as I've only just replaced it for a Ceramic speed and don't really want to risk taking it back out and damaging. Has anyone upgraded without removing BB, will the Junction box B fit into the downtube if I remove the cable guide below BB? Thanks Andy

    I don't think you'll need to remove the BlackBerry. The wires should still pass though it. I had no issues in my S2

    I believe you can work around it and don’t have to take of the bb. I bought a jag wire internal route magnet tool on eBay that helped a lot.

    Just reading this... I just upgraded my S3 over the same issue. I went to E-Tap. Really simple install. I liked it so well I upgraded my R2 also.
