    Transonic Di2 Internal Wire Access
    Hi all-

    New to road biking and electric shifting, long time MTB'er.

    Anyways, got myself a Transonic and it came outfitted with Di2. I am looking to install a bar-end junction and need to extend the Di2 wire that exits the downtube for a longer one so it can reach the bar-end junction.

    Question, how do I access the internal junction box? I opened up the door under the BB, along with taking off the cranks and peaking inside the BB itself. I don't see how I can get to it.

    Any ideas?

    Even though the question is sort of specific to your Fuji bike, you might want to ask this question in the Components/Wrenching subforum.

    Did your bike come with the 3-port junction that goes under the stem, if so would getting the 5-port junction help? Can you add pictures?

    Thanks. I got it figured out. Because I was not familiar with Di2 and road bikes in general, I didn't realize my bike came with a BB conversation kit (Praxis BB Conversion) which has a internal plastic sleeve which was covering the access point for the downtube Di2 wires/junction box the first time I took everything apart.

    Got it figured out and getting ready to finish up my new bars/bar-end junction setup.

    Oh yeah, makes sense. Sometimes that sleeve gets stuck when you pull the rest of the BB out, too.
