I'm sure this will not be of any interest to most riders.
I wanted to see whats going on in the bearing world. I've been away from it for so long now, and I found this site and this info.
It is really damn dry reading, but I think it backs up my outdated description of bearing grades.
Some good info in the FAQ's also.
