Just a thought I had about them. Tell me what you think. I think the real reason they dont last is because they are not truely sealed. Since they are dual inner raced seperate bearings, water gets in thru that crack in the center -its not sealed because I have put grease into the bearings before using my fingers to force it in thru that split....and if you seperate them, you can see how they are not sealed.
So I'm going to experiment and use that black gasket maker to silicone and seal the bearing to the hub...So what do you think? Good, bad, no difference?
