How about a thread specific to Shimano Di2 for those who enjoy it or are interested?

Interoperability, customization, how to questions, etc.

Lets keep the discussion technical. Please.

I'll go first with a very basic question...

Where/how is the B junction typically mounted?

I know it goes inside the frame near the bottom bracket most of the time but is it just shoved into the frame and left to dangle or rattle around inside? Is there a way to secure it inside the frame or is this a non issue?

Wrap j-box in some foam, wrap foam w short piece of tape to keep from coming apart. Shove padded j-box up into frame.
