After a couple of weeks riding, I noticed that my saint rotor was starting to move. Theres the aluminum lockring part that connects to the stainless steel disc part which is contacted by the pads. The connection between those parts are via rivets/pins? They are all moving. If you hold the wheel and move the stainless part of the disc, it rocks forward and back. So if you held the brake and move front and back, you could feel it move. Have any of you had this problem? I'm just scared that it would kinda shave metal away then one day i hit the brakes and the rotor snaps lol.
