I've taken that line of thought for a long time, but have recently been changing my thoughts on that.

It's similar to Chris King poo-poo ing internal headsets. That was a horrible move for them and many years later they are trying to find ways back into that market without looking like hypocrites.

FWIW - Chris king hubs are also cartridge bearing.

...same with Phil Wood...

....and DT and Alchemy and White, and Tune, etc...

Turns out its because they work, and work well. I can blow out a bearing and simply replace it and not lose the hub. With cup and cone once the bearing surface is worn out it's done.

the reason I have so many T11 hubs right now is because I am fitting them with Enduro's new Angular contact cartridge bearing. They are essentially cup and cone now without the bearing surfaces that will wear out like Shimano's will. With the tool I designed I can now perfectly set the preload by simply using a skewer....much easier than cup and cone adjustments ever where (having done those for the first 20 years I worked on bikes)

So...old thinking. Doesn't hold true in reality.
