Justa about always, there's one closer than your garage pump ;-)

I'm fine with fitting and refitting the adaptor - if only any of those
I've known would work ... Could I possibly have a problem with a
particular Presta valve/tube??

Since I have diferent tubes in the front and read wheels, I'll try
both one of these days - I normally try with one tyre/valve, and given
the bad result don't even try it on the other wheel ...


Thanks,

The above with gauge. Learn its quirks at home.

I've been using Zefals for 30+ years, never been stranded, also never
tore off a valve stem. If you pump with the wheel off the bike, and pump
into your fist, letting the wheel swing free, it'll never happen. You
have to be a bit more careful when the wheel is mounted.

There is no reason to switch to Schrader. CO2 cartridges and the
inflator don't take up much room, get an Innovations brand, buy one
that doesn't need thread on cartridges. Cartridges are cheap, when
bought at wallyworld type stores. Buy them in the paint gun dept.

The above will solve #1 and get you going quickly. For #2, as
recommended by many, and me, earlier, get a Topeak Road Morph.

As to the adapters, everyone should carry one for the unexpected,
every LBS I go into has a bowl of the Kool Stop style. Here take a
look: http://koolstop.com/brakes/accessories.html#valvestems
If that style leaks, odds are, you are doing something wrong.

The Road Morph is the best choice. If you're a really tricky fiend, you can
take the hose (with gauge) off the Road Morph and put it on the Mini Morph,
and now you have a 9-inch long floor pump with a rudimentary pressure gauge
instead of a 13, 14-inch pump with a rudimentary pressure gauge.

Oh, about 0.008hr if the pressure if you're just 'topping up' and your
pressure is already around 70-80psi. If going from 0psi - 100psi it takes
me about 0.034hr, if I'm half asleep, using my Topeak Morph, putting the
bottom on the floor and standing on the hold-down tab so I can use it like a
floor pump.

I too am now in the market for a mini pump. This one seems to be the
group's fave - or at least those on this thread.

Can anybody comment on the Crank Bros mini pump? I like the Crank brand
because it seems to be a brand with innovative ideas which improve
product. This pump claims to have two modes - fast, low pressure and
slow, high pressure. It seems to make sense to me having those two modes
so I inquire.

I don't wish to carry a full sized pump.

I think cartridges are a very good idea for inflating, I just never
thought they'd work with Presta valves.
I'll look around.

All the adapters I've seen so far look just about the same, and not
very diferent from the ones you pointed out.
So, I must be doing something wrong - the thing doesn't bring an
instructions manual ))

Thanks a lot.

Say again?? How are those 2 pumping modes supposed to work?

_ I think it has two barrels inside and you can switch between
using 1 and 2. Or something that effectively narrows the diameter
of the pump somehow. It does work, but it's still incredibly slow
and painful to get a tire anywhere near 100 psi. It's okay as a
backup to a CO2 inflator, but them you end up carrying more
weight that a good frame pump with a less reliable system.
IMHO, you'd be better off carrying extra C02 cartridges.
For MTB tires and pressures it works reasonably well, but
not for road tires.

_ The Road Morph is a fine pump, I use it as my daily pump in
my office at work. A long skinny frame pump is the best if you
know how to use it effectively, Road Morphs are nice in that
they are tired brain proof, if a bit more strokes.

Most modern day pumps and CO2 inflators are designed foremost for
presta use, with Schrader as a secondary consideration. All decent,
modern road bikes use presta valves. Most road rims, and wheels are
drilled for presta.
If anything, most of the pumps and CO2 inflators will work best with
presta.

Joking or not, if you think an instruction manual would be helpful, it
might be best to have your LBS mechanic, demonstrate proper use of the
adapter.

Naturally I was joking - partly because I make a living mostly
translating manuals - but I begin to suspect I'm doing something wrong
with these adapters, therefore, will ask at the shop where I buy 1 or
2 (more), for a demonstration of how the thing is used.

Blackburn FP-1 frame pump put 140 psi into a tubular once without too
much trouble. I used a gauge on it when I got home. I use this pump
on all of the flats on my rides and rides with friends. The tires
usually end up much harder than when they started the ride. Again,
without too much effort since it has a long barrel. It can fairly
quickly be changed from presta to Schraeder if needed.

As for going with Schraeder and using the pumps at gas stations, many
gas stations that serve cars exclusively have their air compressors
limited to 80 psi at the most. Or lower since cars never ever take
more than about 40 psi. SUV and pickup tires designed for trucks may
take up to 60-80 psi. You would need to go to a truck stop that has an
air compressor for semi truck tires to get bicycle inflation pressures
of 120 psi or so.

Knowing how many strokes it takes from inflation at home with a gauge to
hand.

I can get to 80 or 90 with my mini pump. If you don't have a gauge,
compare the pressure with the tire that was not repaired. You can get
close enough and you just need to be more careful about RR tracks,
potholes, etc. If you have the ideal size (most people use tires too
skinny for their use) tire for your weight, 70 psi should be fine if
you are a bit more vigilant about road hazards.

How do you estimate tire width respective to body weight??

Bought another adapter yesterday.

In one of my tubes, it stars to leak through the bottom of the
adapter, as soon as I start pumping; on the other tube, it immediatlly
starts to leak, through the same place, as soon as I lock the pump
conector on the adapter, and a pin pushes the top of the Presta valve.

I'm going back to the shop, even because I did not even pay for the
adapter yet, as I did not have a 1 euro coin, and the man did not have
change for a 5 euros bill, and tell him the story, and see if he can
make a real life demonstration of the thing working.

I really love this adapters!
