I've got a nice SKS Airboy:

Which is hardly longer than a water bottle and clean looking enough that
even a vain FM like me can stand to have it on his downtube.

You're letting the FM side down, its not carbon.

Do Assos make a pump ?

Anyone know the correlation between the pump/CO2 and helmet/no-helmet Nazis?

Good question. I am pump/no-helmet (although: "more than two is a helmet
clue"😉. Is that a typical combination or not?

Yeah, plus they cause global warming.

I was wondering what caused that. Who'd of thought I'd find the answer by
reading RBR?

Good, I won't have to keep holding back any farts anymore.

Curious that you didn't say "holding back _my_ farts anymore." Whose
farts are you holding back and how?
Scratch that - I don't want to know.

Right. This is why I skip the Silca pumps and CO2 cartridges in favor
of a gasoline powered air compressor.

They're coming out with a titanium version for cyclists.

Now if I could only find some replacement rubber feet for my Campy
head...

Hardware stores have rubber tubing that works fine and is dirt cheap.

A few coatings of tool dip oughta do. That is not a tapping comment.

You guys are all missing the point. It's not a question of utility.

I'm sure that somebody make a tool dip in Campy blue, but it's not

I sorta like Silca pumps but I used to have a girlfriend who preferred
Manolo Blahnik pumps.

Greg pays you enough to afford not only lunch rides, but

You wouldn't believe how expensive they are

Um, no, not exactly. She was the one who could afford me.

Yeah, till she found out your idea of a party was pareto optimum

She had the nicest footwear in grad school. Last I heard, she married
some guy who didn't worry about resource allocation under constraint.

There are limits to (keg) tapping at grad school parties? Ugh.

That's another reason why you have to use the $$$ campy head. It
mitigates that effect.

I was wondering what happened to Silca...? I believe they still make
the floor pumps. About 7 or 8 years ago Performance carried the Silca
frame pumps which was nice. Yellow Jersey carries the frame pumps, but
they are are expensive @39.95. Does anyone know who the US agent or
importer for Silca..?

Today I found a Campy pump head.

Dumbass -

Quoted message said:

No offense, but Silca products were junk.

Quoted message said:

Why do you want a frame pump?  A CO2 device is smaller, faster, works
better, and has no chance of falling off your bike into your spokes
and killing you.

Probably because a pump works twice.

Well that is the lifetime of a Silca + Silca Head.

Who do you think Robert is, Wilt Chamberlain on nuclear viagra? I think
this was probably more like the "one in a fairly small number" woman.

I don't see where the head comes into this. The failure point was the
plastic threads retaining the plunger. I did have the Campy head.

Hmmm. Maybe I don't know, but I had thought _one_ of the reasons this
common effect occured in Silcas was because the head did not allow the
presta valve to reseat properly after a stroke (and unseat easily
during the stroke), and so the high back pressure would shoot the
plunger/handle backwards. I never gave it a lot of thought, as it
seemed to only happen a lot with Silca.

But now that I think of it more, the Silca is a very old design, only
really made for higher air volume and lower pressure (50 psi or so for
bigger tires). So with that sort of chamber/design, maybe the valve
would not get opened (at all) until the stoke was nearly complete,
creating a lot of pressure up till that point, and then manifesting
this effect users of Silca have experienced. Maybe you're right --
maybe it had little or nothing to do with the head.

In any case, I would distinguish between the threads failing and what
seemed to be an unusually strong reverse action (that ended up causing
the thread failure). I saw it with the campy head too. But it seemed
like it happened less, but for all I know that could be coincidence.
The stock heads did not last long.
