My opinion is that some of the inserts are just off from being perfectly straight by a little bit and it puts stress on the inside of the bearing also if you are running the axles and front hexes I have noticed if you tighten your front wheels to much it pushes the hex up against the bearing and it feels gritty and has a lot of drag. I am actually going back to the stock axles bc I am tired of pulling the hexes away from the bearings.
