Sealed or open hubs (suzue)

Based on what? All bearing are different.

Cartridge / industrial bearings are simply loose bearings in their own races with lube, and sealed up with side walls, so are not inherently weaker or stronger simply because of this. You do talk a lot of rubbish.

buy the best components you can afford. Good equipment pays you back. Stripping and repacking hubs isn't my idea of an afternoon's entertainment...
