    Black cable sleeving along top tube?

    I have another question about fixing up my 1993 KHS Montana Comp

    The cables for the back brake & front/rear derailleurs run along the right-hand side of the top tube but they aren't bare cables with o-rings, they are protected from the elements by a black sleeving.

    Because this bike is 17 years old, all that black sleeving has split, worn away and just looks very scruffy, so I'd like to replace it.

    After a few hours of searching google I came across people recommending "Heat shrink sleeving" so I bought some off ebay but it's not the same stuff heat shrink sleeving is much more flimsy and I dont think it will be long before it splits/ wears etc and it also isn't really a glossy black like the original stuff..it's more dark grey/matt.

    So after another hour of searching tonight I found this stuff..."Jagwire Black Housing Liner"

    I think that is exactly the stuff I'm after! but I can't find a single shop online to buy it from in the UK and I really don't need 30 meters of it, more like 3 meters.

    Does anyone know where I can buy this stuff from in the UK?

    You don't need it. It doesn't protect your cables from the elements (if anything, it traps moisture and causes them to rust quicker), it protects your paint from being scratched by the cables when off-roading. More easily available cable donuts do the same thing, but if you're not off-roading you really just don't need them.

    here is the trick that I use, if I want a plastic sleeve for anything, just use deralleur housing and put a slice down the side to remove the black outer housing. Remove all the linear wires running down the housing and there is a perfect sleeve. Also works well if you need to make a plastic sleeve to use as a guide for replacing cables on an internally routed frame (anyone who has worked on a Klien knows how much easier it is to use a sleeve to run new cables). Just be sure not to crease it when you remove it from the outer housing.

    This is what I used. You really need those special end caps to do a good job.

    The 'sealing' is done at the ferrules, what possible difference can sealing an exposed section of cable do? Absolutely nothing.

    The liner is there solely to protect the frame from scratches. With cables that run along the top of the top tube, the simple act of standing over the bike at stop can cause the cable to rub the frame and leave scratch marks. The liner keeps that from happening but that's it.

    Shimano makes an obscure product (most online sites do not carry it) called "housing liner" (http://www.cheapbikeparts360.com/pro...housing-liner/). You might have a better shot at finding it in the UK than the Jagwire product.

    The specially-shaped end caps allow a good seal between the thick housing sections and the thin liner section--without them the joints just open up and there are sections of bare cable exposed. Looks better.
