When we had a local bike shop right here- they carried several different colors of housing. After they closed up, I found the other shops around only stock black or white- which was stunning to me.

What sucks about getting the Jagwire kits for an old bike- the brake housing generally isn't long enough for non-aero brake levers- a good 2 feet of the housing is metal housing that's meant to be taped to the bars for aero cables.

I've bought some of the Jagwire bulk housing off eBay- I was really disappointed- it wasn't the same quality as the stuff I got from the LBS or in the prepackaged kits. Which reminds me, I need to pick up some housing for a couple of projects...
