Getting a presta nozzle to fit on the air nozzle shouldn't be a big problem.
If you're worried about contamination in the air lines, there are several
air-line cleaners available. They filter moisture and oil from the line.
If you're needing 140psi, then yes that compressor is not for you. I have
found mine very handy...good luck.

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?

it's still in the garage.

Eh? I couldn't find any simple presta nozzles that I could
use with a standard compressor. I have to screw on one of
those terrible presta -> schraeder adapters, which just
make it hard to get a good seal.

My Air Slim is a good pump for me. You can even pump up trispoke
wheels and many discs if you switch the schraeder and presta sides of
the pump head. The internals are quite simple. Just press the lever's
pivot pin out, and you can guess the rest.

I have two Silca pumps, the Track pump and a Super Pista. About 15 and 6-8
yrs old respectively. They both work like new, durable, inexpensive, capable
of high pressure. The Super Pista is reasonably high volume. One is on the
back porch the other stays in the car.

i had the distinct pleasure of using a floor pump today which blew any
other ive ever used away for ease, perceived quality, etc. it was
made, IIRC, by topeak, and the model is something like 'joe blow'.

anyways, in efforts to seat a ridiculously difficult-to-seat tire, i
repeatedly pumped a road 25c up to ludicrous pressures, let air out,
did again, etc etc. 160 psi was easier and faster for me with this
pump than using my own paltry blackburn to get anywhere near 100. your
psi may vary.

it also had a very secure and straightforward valve attachment, which
is distinct plus among many floor pumps whose crux involves attaching
the pump, not inflating the tube.

The Silca pumps are great quality pumps especially for high pressure road
tires, but the volume per stroke is rather low compared many other pumps.
For a mountain bike it isn't a big deal, but I wouldn't want to inflate
a car tire with it.

The best bicycle pump for inflating car tires would be the one with the
largest diameter barrel and longest stroke. The blackburn TPS-1 has a
pretty big barrel and stroke. So much so, that it is difficult to inflate
road bike tires with it. Maybe blackburn has resigned the double sided
schrader/presta head, but a problem I had a few years ago was the schrader
head had a check valve built into it which severly constricted the flow
of air to the tire. It considerably raised the effort needed to inflate
the tire.

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.

If the TPS-1 has the double sided head that is on
my TPS-2, then it's certainly better in that respect.

The issues I have with the head are:

-- On schraeder valves, you must attach it very firmly
and make sure the valve stem is as deep in the head
as you can, or you won't get an accurate pressure
reading from the gauge on the pump

-- The head has a piece that you twist to engage it, and
it's somewhat difficult to twist/untwist; and you
can lose air while engaging/disengaging

-- I fear breaking presta valves while engaging/disengaging
the head with that twistage

-- I feel that I lose too much air while removing the head

Well, I think I ought to retract my earlier reccomendation
of the TPS-2. Obviously, I don't like the head; and I'm not
confident that the shaft won't break, either, so the only
thing I like is that I can, in fact, get 125 pounds quickly
into a road tire, and 65 pounds easily into a MTB tire.
