It won't actually disintegrate at that moisture content but that's an unrealistic level practically anywhere and it would need to be unsealed to do so.
As someone who only rides a 200 dollar bike I'm not even sure why you are discussing higher end possibilities anyway.

Dude the bikes are $200 street value now. Some of em were 6k new. Or whatever hideous number they slapped on it when new.
And with your humidity analogy - we will not have dry rot of wood at all in humid climates.
And people wont get dry skin either.

Sorry, its a cells life cycle that causes it to shed moisture. Much like old people need moisturizer more than younger people.

And I am eagerly awaiting the day a bamboo bike turns up cheap. I would then go look at it atleast. May be a long wait.
And bamboo is abundant in China not to mention a lot of SE Asia where China is pushing industrialization, if the bamboo bikes catch on, they will flood the market in no time at all. Victim of its own success.
I can actually think of a few better alternatives to bamboo. There is a wood called casuarina. We use those for poles, they are usually solid, its also very fibrous, we used to make rope by peeling it. You cut a little V notch in it and pry out a little tuft, and pull and pull and pull. You'd end up with a rope that you cant destroy without a pair of tin snips. It probably is as heavy as pine, which again Bamboo is. Only reason bamboo is better than pine is the fact that it is hollow and hence light (OK OK Pine is not as tight grained and perfectly directional as bamboo).
The bamboo has to be hollow, and has to have been treated inside and out for it to have a prayer past a couple yrs outside.
In doors, you can quadruple it easy, and that is for untreated.
Cool.

Probably more interesting than watching bamboo dry, or where this thread went....

He he, some varieties of bamboo grow very very very fast after a long period of dormancy. That oughta be interesting.
Cool.

No. Dry rot is wet rot that has dried out.
You can't have that unless you let the material get really wet.
You really need to do some research. I'm out.

No, you can't, you would miss out on the inspiration of bamboo.

Dry rot is when cell walls have broken down and turned to dust and have no or a fraction of their original structural strength left. It happens fastest when the wood gets wet and then dry repeatedly. It happens slower otherwise.
I have 40 yr old steel bikes, and 20 yr old aluminum bikes. All of those have been in the weather. I would not dream of sitting bamboo in that situation. I've seen it die in 1/10th that time. Coating it slows it, but does not stop it.
Cool.
Srinath.
