these alloys are shot peened or put into molds and no 2 will weigh the exact same the manufacturers give an average weight and most have a disclaimer for anyone that thinks this manufacturing process can produce exact weight clones. the alloys are mixtures and like color lots in paints and other goods there are variences. The nuevations wheels website gives a good example of wheel weight differences and the causes. I wouldn't get too worked up about lawsuits. weight variences are common knowledge in cycling components. thats why most bike manufactuers don't give total bike weights because of the variences of component weights
