Hey folks,

In the "hanging bikes upside down?" thread, someone mentioned that hanging
a
bike upside down causes the frame too stretch over time.

To be honest, I've never heard of a frame stretching problem until I read
that post.

if that's true, could somebody please explain it?

In said post, note my line, "Must dash, Matron has my medication ready for
me to take ;-)"
That should provide a clue as to the seriousness of my response ;-)

Just prop a broom under the bike to take weight off the frame. Then you
only have to worry about compressed bristles.

HTH, BS

It's well known that steel frames go soft over time. Eventually, they get
so soft that they stretch when hung upside down.

Yes, but if you hang it right side up the following winter it will
compress back to it's original size. Also good if you have a Mutt &
Jeff team sharing a single bike.

This is almost as bad a when I heard a tire salesman try to tell a woman
customer that her tire had a bent steel belt and should be replaced.

Rong. Whether you hang the bike right-side-up or upside-down, the weight is
stretching the vertical components. A more advanced theory is that the
compression during riding is high enough to more than reverse the hanging
stretch. Of course, this cannot be exactly true for all rider weights and
relative riding/hanging times. Carl Fogel, do you have links to data on
this?

I'm gonna hang my bike by the back wheel only, so it can stretch
longer. Then I'll put on another seat and make it into a tandem!

I would be more concerned about the compressed air in the tires. As you
know, the air packs down over time and you have to add more on top of the
air that is in the tire--unless you have a leak. If you fill your tires at
sea level the air is heavier than the air in the mountains. Therefore, you
can put more air in your tires at higher elevations.

Gravity acts on the frame causing it to stretch. Initially, the effect is
small, but eventually it can affect handling. The effect is most pronounced
at higher latitudes as gravity is less strong at sea level near the equator
because of the bulge of the earth in the middle. Typically, if one sits on
the bike on a steep hill facing down the hill with the front brake locked
for about 1 minute for each hour the bike has been hung, the effect will be
nullified. Look for a hill with at least a 10% grade. I think Sheldon
Brown has a faq on this, see http://www.sheldonbrown.com/articles.html

I hope this helps.

Do you know that there is no such word as "gullible"? It's not in the
dictionary. Go ahead, look it up.

In addition to your frame being stretched, your spell checker is broken.

If you hang the bike by the front wheel only, and it's a
straight-gauge steel frame, you'll eventually get a
butted frame. If it's an aluminum frame and you leave it
hanging for long enough, eventually the rear half of the
bike will fall off the still-hanging front half.

Carbon fibre is unaffected, but it has it's own problem, in
accumulating static electrical charges and zapping the rider.

Tom

You don't want to ride a tire that has a crimped wire in the bead.

An automotive tire & a steel belt not a bead, you don't bend steel belts.

The bulge at the equator is only part of the effect. Don't forget,
there is a lot of centripital acceleration at the equator that is less
at the poles.

BTW, this is the reason people are so much happier at the equator,
because things are less grave (due to less gravity, the opposite of
happiness).

^^^^^^^^^^^^^^^^
People are happier at the equator because they "get around" more. People at
the poles don't get around at all--they turn in place. It must be very
dull.

The opposite of gravity is levity. If we had more levity, bicycle frames
would't stretch at all--so this thread serves a useful purpose.

This one has been around too often to catch many fish. Do you need
caricatures at the end of sentences in this context to catch the
meaning?
