15 miles into my ride I notice my back tire is bouncing more than normal. I know what that means, a flat is coming. In the past year I have had maybe 3 flats. Two of them were about 1/4 mile from the house and I made it home on a slow leak. The other I patched and used the Airstick pump.
So, I stop, pull the tube, new tube in, start pumping using my AS-1 Blackburn Airstick. About 85% full the tube lets go. I'm like, "what the F@#K?"
Pull the tube, right at the base of the stem there is a tear. So, I grab the other tube and patch it, put it back in the tire, start pumping, 85% full that tube lets go. Now I'm screwed.
I started walking and Ross, who I've never met, pulled up and offered me a tube along with a shot of CO2. 2 minutes later I was on the road. Mucho gracias Ross.
Now, I'm thinking the problem was the pumping action that tore the stems. I held the damn thing as tight as I could against the rim and tried to prevent any movement.
My rim strips are fine, although I'm going to replace both.
Both tubes were Specialized Turbo Ultralight and leaked where the stem connects to the tube.

I'm going to start using CO2 and carry two tubes (pay it forward).

Anyone have a similiar problem/solution?
