I have heard of, but not tried, using a needle and thread. The needle acting as a plumb bob. Hold the bike so the top tube is vertical and drop the needle in (attached to the thread....). Heard this trick after spending 3 hours re-threading the Teflon housing in a 2012 Madone 6.2-lost the housing inside the CF frame to start with.
