I think Zpacks.com sells carbon tent poles. Somebody out there does custom Alum poles. Don't know the source.

I just looked through my pile of thin tiny bungies. I found one that the hooks will hook to a spoke and then around the down tube. I taped the exposed metal to not scratch the rims. And it hooks nicely to the front rack to keep it on the bicycle. The velcro strap for extension cords sounds good also. Look in the plumbing dept for a C shaped hook with a tab that could be taped to the end of a pole and would fit the round tube of a bicycle. It's used to hang pipes from the basement joists. Or try a J hook.
