I'm in the process of changing out my current cables and housings on my BB7's to the Aztec Powerlines but I ran into a small snag. The diameter of the new Powerline housing is smaller than that of my previous housing. As a result of this, the brazed on cable-through guides on my top tube do not hold the housing in place against the frame. The cables just fall out of them every time I turn the handlebars. Any suggestions to create an aesthetically pleasing "fit"? I could use "shouldered" cable stops and just let part of the cable run without housing but I would rather stay away from this as it lets gunk get inside the cables over time. I was looking around to see if anyone made a set of those little rubber donuts in a larger size that would actually fit over the housing as well but I haven't seen any yet.


All suggestions are welcome. Thanks for the help guys.
