    Can an e-tube cable fit in a top tube brake cable stop?

    I am about to pull the trigger on a Di2 upgrade for my internally routed 2014 R3. Some other bike brands have a brake cable stop that accepts both a brake cable and a di2 wire. Is there anyway to safely and nicely hack that into my R3? The reason I want to do this is to run both cables together with heat shrink all the way to the frame rather than having them split to have the di2 wire go to the down tube.

    Why hasn't anyone invented a brake cable housing with integrated di2 wire?


    Thanks,
    David

    Just drill out the stop with a 5mm drill... easy

    There aren't many close up pictures of the front end rear brake cable stop on the internet. However I did find this video, and I am guessing he has done what Harry recommended! https://youtu.be/qiE96Ecw0fs?t=1m3s I wish I they showed and spoke about how he routed the Di2 wire in. I assume that it went down the head tube as the seat post would end the wire's life pretty quick I imagine.

    Are there any other examples out there? Is this the best way to hide the cable?

    Thanks

    It looks like there are two styles of this cable stop. There is an older(?) solid one and a clip fit one.

    Sorry I misunderstood your question.... I’m not sure u will have much luck getting both cleanly thru one hole.... just heat shrink them to close the the brake cable entry point and then divert to the down tube, or route Di2 cable thru bars, into stem, out stem near steerer and drill a hole into the top tube just behind the steerer.... this is the way I commonly route mine now, esp given the invention of the bar end port in DA 9100
