I had a new rear cable and housing put on my road bike in the last 45 days by the LBS.
I have had in the past 30 days sticking on the cable in the rear housing by the seat post.
I have some park lube and re-lubed the cable, but did not pull it all the way through. This works for a while and then gums up and I nee to start again. Flushed the tube with WD40 and that solves the problem for a day or two. The rear brake housing is fine. the jam is in the tube.
Should I get a new housing?
Different Lube or cleaner?
