I am wondering if anyone has tried using graphite powder in their cable housing as a lube? My bike was ghost shifting so I went through and did some trouble shooting. I checked the deraileur hanger and it was in perfect alignment. So I checked out the cable housing for any ends that could be causing friction and found a couple that needed attention and so I went through each cable stop and touched up each one.The housings are clean because they are brand new so Im reasonably sure they are clean inside. I replaced the cables and put some graphite powder down the cable housing and I am getting some of the smoothest shifting ever! BUT....I wonder if there will be any complications down the road because I used graphite powder. Anyone have any experience with this kind of deal? I did a search on the forums and didnt find any posts about graphite powder in cable housing.
