stetched frames?
Cully_J
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?
regards,

In said post, note my line, "Must dash, Matron has my medication ready for

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.

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

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?

longer. Then I'll put on another seat and make it into a tandem!

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.

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.

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?

Good point! If you plan to store your bike for long preriods of time, be
sure the valves are positioned at the top, or they may become clogged
with air, making "topping off" difficult or impossible, requiring
replacement of the tubes.

None of that foolishness would be necessary if you'd just remember to
completely change the air in your tires every two weeks. Only stale and
lumpy air will clog the valve, irrespective of the valve's position. Fresh
air won't cause the problem at all, and only lazy people "top off" anyway,
and they deserve clogged valves.

sell kits, but have been having trouble locating a Canadian manufacturer of
suitable small lightweight equipment. Probably easier to find equipment
vendors in the US.
If the change is not done properly, permanent damage to the tube, tire, and
possibly the wheel, may result.
