Michelin Dynamic on my son's bike require between 73 and 105 PSI.

73 psi sounds way too low. If this is a 700c x 25mm tire, about 100 psi
would be right.

Man, how can you reach 105 with an hand pump ??? (Axiom Pump good for
120/130 IIRC ) .

I think that's a mini frame pump. You really need both a good floor pump
for normal pre-ride inflation, and a full size frame pump in case you get a
flat during a ride.

I like the Silca floor pumps. But whatever floor pump you buy, replace the
chuck with a brass presta head. See:
http://www.sheldonbrown.com/harris/tools/tire.html

For a frame mounted pump, it's hard to beat the Zephal HPX.

Second question , can you put a tube equiped with a schrader valve on a
bike delivered originally with presta ?? ( alex wheel) Is the hole in the
wheel big enough ?

No, it's not. And it's not a good idea anyway. Once you learn how to use the
presta valve properly, you won't want to go back to Schraeder.

Forget the adapters. Get the brass Silca presta head, loosen the presta
valve cap, give it a quick tap to free it up, press on the silca head, and
pump away. I can top off a tire in a few strokes this way with no leaks or
hassles.

You use a Zéfal HPX.

But it's worth having a track pump at home as well.

My LBS sells a brass adapter for presta for 0.79$ Use 'em to fill up presta
tires at gas stations...

Use the hand pump to push the "on" button on the air compressor.

You got it. Take a look at the Topeak Joe Blow series of Floor Pumps.
A bike like your son's requires that the tires be checked and topped
off, at least twice a week. I check and top mine off before each ride.
It takes 1-2 minutes to do. [I usually ride 4-5 days a week, about 9
months of the year.] You really do need a floor pump.

A good compromise,for the on bike pump is the Topeak Road Morph. Not
the lightest or most compact.

Another option, for on road repair, is a CO2 inflator. You can buy the
cartridges cheaper from somewhere that sells them for paint guns or
air rifles. Just be sure to carry a minimum of 2, I usually carry 4.

Whatever he settles on, learn to use it at home. As others have said,
run about 100psi, if tires are 700x25.

I second the Topeak Road Morph - I can get tires up to 120psi or higher
with no problem with it. You can 'morph' it into a mini floor pump,
setting in on the ground. I've had a full size frame pump before, and
never had any luck getting it anywhere near 100psi.

Heading toward the LBS ... thanks !!!

I second using CO2 on the road. I've had to bail myself and my riding
partner out on the road with one and they're the ticket when you want to get
going. I think you can get to 100 lbs using one so you're not riding a mushy
tire. I carry about 4 or 5 cartridges with me all the time.

I think thats the way will go, my son just cut his first valve stem this
afternoon trying to use this goddam hand pump...

Morph pumps have short hoses, virtually eliminating this problem.

I can't remenber the site but I recently purchased a mini floor pump
that gets over 100 psi for $25. Fits in a bag that has straps for
mounting on the frame.
The first time I used it, it worked great. Rather than beat your arms
to death, you can use you feet. Replacement parts cane be ordered and
its a very light pump

Really? I've never had a problem with them on my commuter MTB. I
guess I tend to be wary of strange pumps anyway: pump briefly, check
tire, pump briefly, check tire, etc. I will take your comment to
heart, however. Sounds like so far I just lucked out.

The last time I had to stop at a gas station to pump up my road bike,
my very next stop was the LBS to replace my worthless mini pump with a
proper frame pump. I love the thing. Hopefully I won't be looking for
a gas station anytime soon. :-)

Mini handpump returned to the store, traded for a small CO2 pump since I am
now convince that we should use only the small pump for road emergency . We
have now a floor pump ( Axiom Propel air DLX ) I know that some other were
suggested here but that's all we could find around here at a decent price,
furthermore we tried it and works great up to what we need 1005 PSI .

Thanks to all of you , you are a great gang !

I think the pump at the gas station nearest the house has a reservoir
set at about 60-80 pounds. If a tire was seriously flat, I frequently
couldn't draw enough air to kick the compressor on.

But a good floor pump, for instance a Silca, works very well.
