And I almost made it to work too. I got close enough to walk the last4 blocks, and found out the Topeak customer service department thinks my Master Blaster needs a rebuild after three uses when I called to figure out why it wouldn't work. I've got a spare tube in the rack trunk and my GF brought my spare floor pump I leave at her place over, I'm hoping to change the tube and ride home tonight - wish me luck!

Your pump probably froze up from disuse. I avoid problems like that by getting flats regularly.

It spent plenty of time in the rack trunk - and still pumps fine. It just doesn't seal anymore Maye I should have used it instead of the floor pump for the weekly top off.
