an insanely low spoke count such as 10 or less spokes? i know it would flex like mad and last sth like 100 miles, but it would still be interesting to try.
Anyone ever done sth like this or seen it done? Any reason why it would be physically impossible to actually BUILD this?

Nope. I haven't done that to tell you the truth. I think less spokes is putting your life in danger. Besides, where are you going to get the hubs and the rims. There isn't a manufactuer in this world that is going to put out such a thing due to liability issues. I think your ranting has more to do with you having cabin fever and hoping to have something to talk about rather than deal with reality that it is still a few more weeks until you will be back on your bike.

lol yes i am desperate to get back on my bike, and i would obviously not use a wheelset like that regularly, but i'm just curious. is it actually possible to build a true wheel with that spoke count? i guess u could just get a standard 24 hole rim and just lace like every three wholes. After all is only an experiment.
What? You've never counted the spokes on a Rolf? nmMShaw

Yep, the least they have is 14. Can it be done with less? nmKaboom

The first Campy Shamals had 12.jw25

As do some Lew front wheels. I think Rold had prototypes with fewer spokes (I'm thinking 8), but they didn't make it to production.
The thing with low spoke count wheels is, you put a lot of lateral stress on them, since the span between spokes is so large. That's the idea behind paired-spoke wheels, but then you still have long unsupported sections that require a deeper rim to avoid radial flex.
That's why most low count wheels have deep rims, not so much for the aero factor, though the two do go well together, but for the radial stiffness.
So, I guess you could, but you'd want a deep rim to start with, and possible paired spoke lacing. In the end, though, the small weight reduction is offset by the increased rim weight, and spoke tensions need to be higher as there's fewer spokes sharing the load. Factory built low spoke wheels have strong rim beds to withstand this extra tension, where a 28 or 32 hole rim might not.
And finally, do you really want to be riding a wheel that might catastrophically fail? Me, I like my teeth where they are.
I have a 12h DA and 12h Lew that I will build soon...TFerguson

but I'm certainly not going to put my fat a$$ on it.
