I think they are legal.Technically bamboo is not wood, so following the rules as they are written you could only use 15% bamboo in a blade.
That said it is a natural product and within the spirit of the rules, so I doubt it would be a problem. I think I remember reading years ago that the ITTF treat Cork and Bamboo as woods, they just havent updated the rules to include them.
