My rear tire was really, really spongy on the way home from work. When I got back to the garage I tried the pump again and it still wouldn't work. I tried it on multiple bikes (presta and schraeder) and nothing. Then I tried pumping it by itself (not connected to anything) and the handle wouldn't depress. It felt like I was compressing air, but no air was coming out of the end.
I've had this pump for 12 years and decided that maybe it finally bit the dust. I brought it inside and looked up hours on bike shops. There was one that open until 9 PM, so I decided after I ate supper and did a video conference with my son's teacher I would run and buy a new pump. My rear tire wasn't going to make another trip to work without some air.
After a couple of hours I walked by the pump sitting there and on a whim gave it a push. I could hear air coming out again. I took it out to the garage and pumped up the tire just fine.
I'm thinking there was a little moisture inside the pump and in the extreme temps it froze and rendered the pump unusable until I brought it inside to thaw out? In any event, I'm going to test it when I go out to the garage this morning and see if it's stuck again. I may just have to start keeping it inside the house when the temps are below zero.
