. How much does it weigh? Same as a stainless wheel or is it less? Looks like most of the stiffness in the wheel comes from the thickness of the wood, is the carbon mainly just for show? Or do you think it contributes significantly to the strength?
Did you use carbon tubes for the spokes? They look sort of bumpy to me but the image isn't very good so I can't tell. If you made them by wrapping carbon tow around a form it can be tricky to get the tow to lay flat. Usually build up coats of epoxy and sand smooth but that's not getting you an optimum fiber to resin ratio. You probably know that, but bumpy spokes?
