I assume your shift cables and housing are not routed along the top tube.
Correct. I was thinking of replacing all cables at once, but just got off the phone with a LBS and they said, bring what you want replaced and we will cut them for you and you can do the work yourself. Sounds like a plan. They have Jagwire, Shimano and several brands to choose from.
