Just out of curiosity, is there a "torque wrench" pump or
compressor? I.e., you would screw on the presta valve, set
the gizmo to e.g. 35psi, engage it, and instead of watching
the indicator, automagically at the right level it would
Most of the gas stations here use an air station that you can
set for your desired pressure and then just plug the hose onto
the tire valve
- there is a little clamp to hold it there. When the tire is
inflated to the specified pressure the inflation stops and a
Since they aren't manufactured here I had assumed that the
rest of the world had them too.
My experience from 50+ years ago says not to rely on those
things, although I suppose they may be different now.
Back then I blew a tire off the rim with one. I suspect the
problem was the volume of each pumping stroke. In a large sized
car tire, the volume surge with each big stroke would be
absorbed and barely raise the pressure. In a low volume bike
tire, it caused an explosion. That's my guess anyway.
I usually inflate using a manual floor pump with a gage. It's
easy enough to stop pumping when the dial reads the desired
Don't you mean, when the dial reads the desired foot-pounds?
funny. Pressure is mass/area usually. Except on RBT.

Nah, Franki-boy is just bragging, implying that he pumps so powerfully that the sudden increase in pressure in the tube raises the temperature of the air noticeably.
It does raise the question of how short, slight racing mechanics manage to push down the handle on road tubes inflated to awesome bars. I notice my SKS Rennkommprrrressorrrr is rated to 16 bars... of which I use two and a bit, never more than 3 bar
