The metal shielded bearings are a little trickier. There is a metal spring clip that holds in the side shields. Pop the metal clip off with 2 X-acto knives. The clip will probably go flying so wear safety glasses.
I only want to point that removing the two seals of a Ball Bearing is a baaaad move. I only removed one versus some people who removed the two.
The main difference, is since they needed to change the BB two times in a row in a year I don't changed it and I still use the stock BB who came with my kit.
