I heard the same thing at the bikeshop here when I was standing around. Something about how it doesn't like temperature change from inside to out, similar to the bikeyoke. If left in the drop position, it extends easier in the cold. The first "return" in the cold can be so slow as to be mistaken for a malfunction, but this supposedly avoids that. This is what the local shop was pitching to someone who was attempting to warranty theirs at the time, give this a try, come back if it's still not working.OK. Why?
