damage to rims when hanging bike

Quoted message said:

i got a packed garage. so i started hanging my bike by the rims from
the ceiling with a couple of brackets.

is there damage to the rims, i.e. get them out of round or bend, by
putting the bike's weight on them?

As long as no one does anything stupid, such as hanging on the bike and
twisting it in a manner that laterally loads the spokes against the
hook/bracket in a way that would never happen in normal use, the wheels
will be fine. Of course, polymer coated hangers should be used to
prevent scratches.

This is a perennial question. The answer is no- the rims can support
a couple hundred pounds of rider on bumpy roads, 25 pounds of static
load hanging from the ceiling will be fine.

Dear Tim,

Fine? Fine? You think that wheels hanging from their upper
spokes is fine? Monster!

Not only do I hang my bikes from the ceiling, I use the top tube for doing
pull-ups. No damage yet.

Butbutbut [1] Trevor Jeffrey proved wheels hang from their top spokes! 😉

FWIW, my nephew, when he was about 14, decided to use my hanging bike
as a swing. Naturally, I disapproved. But the bike and its wheels
were fine.

Yeah. Hanging bikes by their wheels turns them into ornery cusses. They
keep whacking me in the head when I walk by. Particularly the ones I
don't ride enough. Why, just the other day, my Nuovo-Retro Lightning
recumbent reached out and tried to tattoo my scalp with its chainring.
Sheesh...talk about psycho.

Aluminium rims will be Ok, but don't do it with $400 carbon faired rims
as Mavic Cosmic Carbon etc

I agree. Everyone knows that bikes belong in the dining room.

I'm not sure I agree. Do you mean you, or the bike? :-)

This is clearly abusive, as the top-tube is typically under
compression while riding, you should be using the top-tube for
push-ups, not for pull-ups. Monster!

When suspended from a wall hook, part of the force is exerted on the
wheels, and part is exerted on the tires and wall. If we assume that
the bike's center of mass is 12" from the ground at the bottom
bracket, and if we assume the hooks (which are mounted on 2x4's) are
10 inches away from rear axle, and the wheelbase is 40cm, then you
have a lever arm that is 12 x 2.54 = 30 cm horizontally from the wall,
and about 65 cm vertically.

So the real question should be : will this lever arm tend to wear a
groove in the wall, and the jury is still on in this matter. Also,
when you start riding all the "heavy" air will be in the front of your
tires, which should give you a boost from a standing start in a track
event (but only if your are using "track nuts", there will be no
benefit if using QR's.)

If you people persist in using this very strong expletive so freely, its
meaning will soon become so diluted that it will cease to have any impact at
all.

This is really getting SERIOUS. While you are in a calculating mood, could
you compare the advantage created in this way for riders with ordinary air,
nitrogen or carbon dioxide? Also, does the viscosity of the gas have an
appreciable effect on its ability to transfer its energy to the tire?

TIA. My bicycle and I are in suspense.

You guys are all wet. The tire, being mounted on a spinning wheel, acts as a
centrifuge forcing all of the heavy, compressed air out near the tread thus
increasing the mass moment of inertia. This is why the faster you go, the
harder it is to accelerate. Helium filled tires are in fact lighter than air
filled tires but helium still has mass. What the serious, high speed cyclist
needs is to by some vacuum filled tires.

Think about it. Is there damage to the rims by putting the bike's
weight on them, then your weight on them, then riding over some bumps?
