    Best way to integrate Di2 junction box

    So I have seen some pictures of upcoming stems that should have a hideaway area for the front junction box. 3T Integra Team has this already. I have also heard of other guys who hide the front junction box (3 or 5 port) somewhere in the frame and then run the wires as needed. Those of you running Di2, have any of you tried to clean up the front end to make it look cleaner? Or just leave the front junction box hanging down from your stem?

    I have been relocating front junction box down by front derailleur.It's tucked behind water bottle and you can still trim while riding. You need to run two long (1400mm) cables one to each shifter. It's real easy to clean up front end dealing with wires only and no box.

    Do you have a picture of your setup that you would be able to share? Do you just use double sided tape to secure it?

    Don't have any pics now but basically I fabricate a small aluminum bracket that's mounts to lower water bottle bolt.Junction box wire ties to that so nothing in on frame.It can be real small and on most frames that will put junction box between front derailleur and water bottle cage.You can also wire one shifter directly through the handle bar straight to the other shifter then you will only have one wire going to junction box.

    Re: Best way to integrate Di2 junction box

    If you use a PRO Tharsis stem (designed for Shimano XTR Di2) is it possible to put the junction box inside the stem. PRO Tharsis works great on a road bike even if it is designed for off-road. It is also possible to buy a Garmin/Di2 mount; http://www.racewaredirect.co/shop/garmin-edge-bar-mount-di2-clip/

     @Rick, looks like I missed this.  To answer your question, I glued it underneath the chainstay.

    Why not inside the frame. I don't want to see the device. It does not mather where it is located.

    Inside the frame would be the best location to put everything in. Unfortunately, that would void warranty if you drill holes on my 2012 R5.

    Wait, no drilling of hols, just from the top slide it in. I have put it between my internal battery and the lower junction box next to breaket. I just slided it in from the seat tube. Will this work for you to or do you have an external batery so you cannot get it inside?
