Topeak pump

Quoted message said:

I use a Topeak road morph pump, and it works fantastic. Sometimes I'll even blow tubes because I
get the pressure to high. The problem is, is that it's a monster. I carry it on the top tube in
one of those cheap zefal bags. Now I see topeak is selling a mini-pump, and I'm wondering if
anyone has had any experience with that pump? Can you pump it above 100 psi easily? I usually use
120 psi in my tires.

I've had a Topeak mini for a couple of years (actually I have 3, one on each bike). It works better
than some other brands I've tried (notably Zefal), but I've never used any mini-pump that can exceed
about 80 psi. That's plenty to get you home after a roadside repair.

Blackburn AS-1 would reach 110 psi, but it would take ~ 400 strokes. I just use full-size frame
pumps now... and a Topeak Morph on my tourer.

My Crank Bros will reach over that. It has two settings: high volume (hard to pump as the pressure
goes up) & high pressure (*lots* of strokes to get the pressure up). Of course, I only need the high
pressure setting when I'm helping others -- I ride a mountain bike 🙂 I don't know how high it'll
go, but helping one poor biker on my way home from the trails, I took his tire up over 100.

scared the hell out of me. I was on the road, pumping it up, and I knew that the tire was rock hard,
but there was still air going in. So I kept pumping and then BAM ! Made my ears ring.

two bucks says the tire wasnt seated correctly. pumping to true tube failure takes some serious psi.
Serious PSI, that is.

If you use a hydration pack, will it fit inside that? I use a Mountain Morph (on the road), and it
fits inside my CamelBak Lobo beautifully.

I have a buddy that uses the "Twin Master Blaster" (double barreled). He swears by it.

Whatever, I strongly recomment you stay with Topeak just because of their (so far) excellent
customer support.

this isn't rocket science, everything was seated PERFECTLY, now shove that lame walmart pump you
got, you know where.

This is the pump I'm riding with and I will say that it's the first pump I've ever had on the road
that actually makes it easy to over-inflate.

Having read this thread through I am puzzled.

What is the advantage of mini pumps over frame pumps?

1)Work better? Seems not!

Takes more strokes than a full sized pump, more fiddly to use.

2)Easier to carry? No

Frame pump just clips in, mini needs bag or bracket to carry it. My seat back is too small to fit a
mini pump in.

3)Lighter? Possibly (possibly not)

I have data for Blackburn pumps. Minis are about 50g lighter (but add back the weight of bag or
bracket to carry it). You need a bigger bag with a mini pump so this IS added weight.

Is this another case of marketing over function?

Yours provocatively,

The single advantage I see is that a mini pump is more portable than a frame pump - thus the removal
to a carry bag to prevent theft when parked is simpler. The really mini pumps, about 6 inches long,
are even more convenient - the extra effort for inflation is no major issue IMHO.

More easily removed and carried around when you're off the bike.

Did you know if you have a fat 2" tyre and a skinny racing tyre at the same PSI, the fat tyre is
more stressed by up to 3 times the tension than the racing tyre? Thats triple the force pulling the
rim apart at the beads. Thats why generally the fatter the tyre, the lower the rated pressure. So it
is much easier to blow a fatty of the rim.

But I don't carry it when off the bike, why would you want to? It only comes off the bike to pump up
the tyres.

(In response to anticipated reply, no-one has ever stolen a frame pump left on my bikes in 35 years
of cycling - maybe thieves would rather have someting smaller and easier to conceal?).

I have never had a pump stolen in over 35 years of cycling - perhaps a full size pump is too big to
conceal easily, or maybe I ride bigger bikes than would be thieves and a 22" pump wouldn't fit
their frames.

Nothing must be easier to carry than something, no matter how small.

You are fortunate, then. My score is two. And, by the same logic that makes me carry a spare tube
and spare patches, I don't care to risk what may be an admittedly small chance of returning to a
bike to find the pump stolen, and then getting a flat.

The idea is, you look pathetic messing around with the miserable piece of [censored] until someone with a
frame pump comes along and finshes your inflation job for you.
