You guys know who makes Specialized cables, on there upper end bikes, its like a clear plastic over a color like center, Ive never studied them, just a quick glimpse, thought they were cool.
I believe that jagwire makes the specialized cables. they do look pretty cool.
personally, buy some basic shimano for a full housing, and shrink some 1/4" heatshrink on to make them an awesome color. If I get bored I'll probably make the brake lines on my DJ white
