OFF TOPIC:
Do you think the 950 inner front hub bearing would be 5x9x3 as listed here on Avid's bearing website?

I have used the $1 Avid bearings and they are great bearings for the price!
Lastly, I purchased the 10x15x4 bearings that go into the circular belt tensioners and I do not know why! They are always smooth when I check them and simply do NOT wear out!
