Thanks. I have that same pump. It took quite some time to actually get it to inject air into the tube - like I said: new to presta valves. Also, after finally getting to about 100 psi or so, the pump was scorching hot. Bahh, I was cursed that day. In addition to the flat, I also broke TWO pairs of cycling sunglasses, scratched up my computer and banged up my fenders! I'll get my mojo workin' again next week. I hope.
