i guess you could use the nokon as a replacement for the standard outer and run it direct into the pauls brake pipe but whats the point? cant see it making it much better.
The point is that Nokon is hugely more flexible than standard outer* - if I had used standard outer there without a pipe, it wouldn't come anywhere near working. It would just push the left side brake arm into the rim, even if you disconnected the brake tensioner altogether. Nokon doesn't push it into the rim at all.
* but totally non-compressible along its length of course
as for the siezed up issue, as the outer didnt actually sit 'in' the stop as is the problem with dog collars, it was ok when lubed up but as soon as rain and dirt came on the scene it stopped working all together, i had to turn up the tension on the springs to excess for the brake arms to return. in a word- rubbish
The Nokon system is a 1mm cable within a separate liner and Nokon links outside that. If you look on my photo, I have run liner through the dog collar and an inch or so forward, and that keeps the cable sweet. But if that wasn't good enough for extremes, you could run liner all the way.
