So i got my new Hayes V6 160mm rotors today and put them both on, they look very spiffy. I go to adjust my BB7's and realize they are BOTH warped. What the? They are brand new. Is this common? I torqued them in a star pattern. Half the reason i got new ones is i was tired of trying to true the old ones. I got them pretty close to straight but seriously. Also they seemed alot easier to bend then my old Hayes rotors. Are some brands easier/hardier to bend back into shape than others?
