How to store a bicycle for an extended period of time? What's the best way to store a bicycle for an extended period of time, say 2 months?
Doesn't really matter.  Just try to avoid really wet places.  I have left bikes in the garage for years.  Or for months at a time between rides.  (Road bike during the winter, while I ride my MTB to work, and vica versa).

I have left them standing on the floor.  Hanging from both wheels in the ceiling.  I recall a thread on hanging from just the front wheel and consensus was it did not matter.
