"Strange" object attached to downtube

If you are willing to accept the "heated" version, by just doing a
quick search in this group or rec.bicycles.racing for "helmet" you will
find large quantities which can be downloaded for free.

Although 100% nitrogen may have its advantages, I have had great
success with a carefully tailored mixture of 78% nitrogen for filling
tires. Use of this compound has resulted in the lowest rolling
resistance that I have been able to perceive. I have noticed that
sometimes merely topping up a tire with the mixture will lower its
apparent rolling resistance dramatically. I began using this mixture
quite some time ago when I seredipitously stumbled upon an inexpensive
source which I believe will serve my needs for at least the next ten
years and probably longer.

I must confess that I have been so pleased with the effectiveness of
the 78% nitrogen mixture that I have not attempted to determine whether
some other percentage such as 75% or 80% might be better, but I suspect
that, in any case, 78% is the sweet spot of the performance/cost curve.

Mail order, just like the IRS. How much you got? Send it!

What is that cylindrical object attached to the downtube of Bobet's
bike?

For a brief time, Schwinn Varsity models such as the one pictured came with
an optional pipe-bomb cage.

N2 has the slight advantage of being much less soluble than
CO2 in rubber, so it wouldn't lose pressure as fast as tubes
filled with CO2, but unlike CO2 it wasn't a liquid at the
usable pressure and temperature, so the cylinders were much
larger.

Yes, but that was only for the Irish models.

Heat is good. Hot air rises. So the heated one should make my bike feel
lighter. Which button on my computer do I need to push?

Dear DR,

Maybe you missed mine. Google a bit for why nitrogen is used
in tires and you'll soon come up with differences between
80% N2 and what they were using.
