I have not had much luck with the Racor pull up ceiling bike hangers. Crap quality. If you look at them, they are all made in the same Chinese factory so go for the cheapest one if you want to try them. Unless your ceiling is too high, simple hooks to hang the bike by the wheels work best.
The best ceiling bike storage system ever made was the Wrench Force deal from Trek. It is no longer made maybe due to the fact that it was almost $200 retail! May still be found at some Trek stores.
