Here's something to keep in mind..... the maximum psi includes you on the bike too in addition to the air pressure in the tire already.....
~~~~ By the way have you guys ever seen a tube with a two piece presta valve? (like the top part can be screwed off) I recently had mine changed at random BS after a flat and they installed one of these... I realized it when I screwed off the presta adapter for my floor pump and it screwed off the top part of the presta valve too (releasing all the air).... I was able to rescrew it back anyway
