I have a set of 3 Park Tool nested plastic tire levers as well as the tire tool that is on the IB-3 multi-tool in my underseat bag. They have gotten a few "field tests" too, so I can attest to the good feeling I get when I have a flat and open the bag to find those little darlings
waiting to save the ride for me. They both are inexpensive, several manufacturers for them out there. I have a CO2 and a few extra cartridges but I am seriously considering one of the hybrid mini-pumps out. I've had to use the old dollar bill boot for a gash, it is a handy trick to know. Sorry you had to make the call, we've all been there, well most of us have
