thanks for the fast replies... you guys are pretty knowledgeable as far as diagnosis over the internet goes... up until now, i've been using an old floor pump that has been leaky... i have never been able to achieve high pressure in these tires... as a matter of fact, i just received my road morph pump today... i knew i needed a dedicated pump with a gauge for my road bike... thought that i could get away without one for a couple of days... but the inevitable moment arrived-- my first flat... oh well, good lesson... better to learn the art of removing/patching/installing a tube sooner than later...
thanks
