Warping/pinging and delamination are common complaints, that are likely to originate in the sandwich of dissimilar metals.
With the exception of the Fender Stratocaster or perhaps a traditional mousetrap most products are in some form of constant improvement this would be a example of this. I never indicated that the Shimano Rotor could not be improved, only a laminate is usually more stable the a solid. I also pointed out the bimetal example is irrelevant because the rotor clearly is not. If solid rotors are preferred by some that is great however Shimano has produced millions of the IceTech rotors with very good market acceptance.
