After reading all the posts about wheel spacer and bearing failures and also seeing my buddy grenade a rear hub as a result of the same, I purchased a kit for spacers and bearings from e-rider. I just took a look at the bearings and its says they are made in China. Anyone have any info on Chinese bearings. I'm personally not aware that the Chinese are famous for their high quality bearings and am somewhat wary about using them. Anyone have any info on this?
