All four bearings of my two rear wheels and one from a front wheel blew out today at the same time, it was shitty. Popped the shields off and they looked fine not that dirty. They wouldn't move at all, like cemented. Axles don't seem bent. Replaced with ones that spun from the gear graveyard box, but damn never had that many seize up like that before. They were super reds and I even kept all the shields on.
