I have seen in a few places cable splitters, which largely seem designed to be used on bikes with frames you can split, as it makes the two pieces genuinely separate. Example from SJS here https://www.sjscycles.co.uk/cables/jtek-cable-splitter-for-inner-brake-wire-black/ It occurred to me that splitters would also allow you to swap handlebars easily - I have one bike I use for everything, and sometimes I would like to swap bars on it - it has John Tomac drops on it but if I do a ride that is mostly off road, it would be nice to put it's original flats back on. If I had splittable cables this would be very easy to do (especially as I use friction shifters) However - all of these splitters seem to fit on a section of cable with no outer, so I can't use them on my bike - the front brake cable needs to have outer for it's full length, and the rear runs only has a bare cable in the run across the top of the top tube so it'd rattle like hell. I also think the gear cables might lie too close to the down tube for splitters to fit in without them touching the frame. Does anyone know if it's possible to get cable splitters that allow you to split cables with outers? Cheers.
