Tip:
If you ever find yourself in position without a pump with a presta end or an adapter find a department store pump and unscrew the valve at the end and insert the presta valve into the end of the hose. I have done this twice and it worked great. I was able to get my tire to the 80 psi of 85 it called for.





ALSO, (stolen from Guggles, off of Bicycle Mechanics forum gave this advice) I have not tried it.
when you get a flat and have no pump, patches or new tubes. you can take your tire off and pack grass or leaves where your tube was then put your tire on and carefully ride to the nearest place to fix your tube. you have to be extra carefull to not damage your rim, but it will get you out of a jam.

I know sounds crazy but desperate times call for desperate measures.
