Inflating road tire, on the road - how??

Hi All,

Before I leave for a ride, it's pretty easy to use a track pump to get
all the p.s.i.s I want in my tyres' air chambers.

Now, suppose one of 2 situations:

1) I have a flat, fix it, and then, how do I get back to pressures of
at least 100 psi?? Naturally, a small pump can get me going, but I
doubt it goes anywhere near the 110/120 psi I normally use. Anyway, it
would just mean I take longer to get back home.

2) Suppose, however, I'm on a longish jorney, of a few days, heading
to a meeting point with my family (whose travelling by car). Even if I
don't have a puncture, what's the alternative to taking the track pump
along for the ride, and use it every morning to set the pressures
right??

Are fat, non Presta valve chambers the answer?

I don know, there are several Presta to Schrader adaptors, so
teoretically I could pump up the tyres at a gas/petrol station.

However, I have yet to experiment one such adaptor that works as
avertised - all I've tried so far let all the air leak, and I end up
with less pressure rather than more - and, how much can I expect a gas
station pump to inflate a tyre? The biggest pressure I've ever put in
a car tyre is 55 psi, which is rather low for bicycle road tyre ...

Sugestions, please?

TIA,
jbr

PS - What's wrong with Schrader valves being used on road bikes
(except for competition use, where every gram counts, and aero matter
counts)??

Some hand pumps are designed for Presta valve use only. Also, the majority
of fellow riders will be carrying pumps set on Presta mode.

I have, on a number of occasions, with great ease pumped up tires to
110-120 PSI with my Road Morph. Why worry about adapters, etc. It
works fine with both presta and schraeder. And I have used it on long
tours, covering weeks. I top off the pressure every few days. No
problem

Topeak Mini Morph or Road Morph. 120+ psi is doable with these mini floor
pumps, even with my tiny 135-lb body.

Topeak Mini Morph or Road Morph. I don't have arms of steel and don't plan
on acquiring them through pump use.

Zefal HP, good for 120 PSI (I do this routinely). If you are willing to
suffer a little more, Silca Imperios will do the same (I also do this
routinely). Lots of other more recently designed candidates as well.

Two thoughts: 1) It's easy to explode tires at the gas station. I've
personally witnessed this twice (one time I may have been the culprit;
memory fades). 2) Presta are easier to work with and more durable in my
experience.

Dear BB,

Among the various arguments for Presta instead of Schrader is that the
Schrader needs a bigger hole, which some consider a bad thing in
narrow, flimsy racing rims.

1) A 16g CO2 cartridge will inflate a road tire to 120 psi in seconds.
These days, many riders carry one or two CO2 cartridges and a small
valve adaptor in place of a bulky frame pump.
2) Switch to standard butyl tubes from ultralight or latex tubes which
have to be topped off every day. A standard butyl tube loses a
negligible amount of air pressure even over several days.

ditto on the 16g Co2 cartridge and inflator, it inflates to 120psi no
problem with 700c23 tires. Great for when you are all tire, hot, sweaty and
don't want to mess with it all.:-)
A long frame pump like the Zefal, Topeak, etc work good too, but the Topeak
Turbo Road Morph is better as it has a short air hose on the end to make it
easier to pump up the tire without tearing the valve stem off. You can use
both hands on the pump then.

Another vote for a Topeak Road Morph, it will solve both 1 & 2.

Presta valves are easy to use and work just fine. The few times I have
had to use a Schrader valve adapter, I had no leakage problems. In
fact the adapter works well, if the stem is too short to get a CO2
pump on the presta head. With the adapter, the schrader position will
lock right on.

A CO2 cartridge inflator would cover #1, but would be impractical for
#2.
