I bought one of those $1 little brass adapters that you screw onto the presta valve to make it a Schrader. Works great!

I thought it would be a pain, but it is just great. I can use my finicky floor pump and my Schrader pressure gauge with a minimum of fuss. (Kona is Schrader, Flossie is presta.)

Might have to get a couple more of those handy little things!

Also got a replacement Serfas pump for the one that exploded the first time I used it. Very nice pump.
