For both bike and car tires, it is hard to beat the Zefal double shot. One
drawback is that the body is made out of plastic, so you have to be carefull
with it. I've had mine for about 10 years now and it still works well.
11 pumps on a 700X23 and I am just over 100psi. 50 pumps or so and I can
get a 195/50X15 tire up to 35psi from flat.

50 pumps??? I can feel my aching back now.

Hey, people pay good money to do stuff like that at a gym. It's even
aerobic!

Eh? I couldn't find any simple presta nozzles that I could

What about this?

Hmm...it hadn't occured to me to try it, but I suppose I
could come up with an adapter from threaded-CO2 size threads
to a thread used on air hoses.

Then I could use my existing inflator.

Thanks for the idea!

Cool, I hope it works. Let me know how it goes. There is a shop here in my
town that carries lots of different nuts, bolts, fasteners, etc. Anytime I
need something specialized like an adapter, this is the place to go.
Hopefully there is a place where you are if you need an adapter.

Good luck

the bottom, I repaired the spring (with a spring cut from a retractable

ingested dirt and other stuff because the inlet was so close to the floor.

Hey, I had one of those and I bought it in 1984. When I couldn't maintain
any pressure in it, I suspected the plastic (yes! plastic!) cup was worn
out. I tried to contact Zefal about parts and they just laughed. So, you're
saying I should look for a spring, eh?

On the side-by-side Zefal it was a bad check valve spring when, after you
push down on the pump, the handle comes back up (not just a little, but all
the way up). This valve is a little bit of plastic with a spring behind
it, the spring corroded, iirc it is all located in the base molding.

Oh, damn! That's not my problem. On mine, it kind of wheezes and I could
pump forever without getting enough air in the tube to bring the pressure
past 20 psi. I figured air was leaking past the cup. If I grease it with
white grease really well, it works for a few minutes---maybe even long
enough to fill one tube. But by the time I get to the other tire, I can't
get any volume anymore.

the compressor we have is next to useless, it just sucks all the air out. ( well
at least the tire adapter is useless as the compressor seems to work fine with
the air nailer.)

Hey! Look what "ameijers" wrote :

I ever get rich/foolish enough to own a house with a garage, I'll have a

Sounds like your check valves are crapped out. They are (usually) 1/4" or 3/8"
brass body valves (fip x fip). They wear out and your compressor doesn't work right
any more. Rather inexpensive, and locally available from industrial wholesalers.
