Yes, hence the Angular contact bearing Wheels Mfg/Enduro Fork seal offer on the DS side to alleviate all of that "angular" issues you have quoted from somebody.
Also, maybe only 2 watts at most. But anything is better than nothing.
Ceramic/hybrid bearings can be made rounder, lighter and stronger than steel to greater tolerance, hundreds of times tighter than steel. Since it is such a small contact area and part of the bigger picture of total drag, it doesn't add up to much.
If people have the money, they can do what they want with it I suppose.
The first, locktite BB30 press fit mouned on my Italian lasted 8,000kms. But the Locktite cuased other issues due to it being acidic. The two other BB30s lasted 1000 kms max each, or 3 weeks? So got the Enduro XD-15 Ceramic, rode it 1.5 months last summer, 2,400 kms, bliss. 500 kms into this season, it began small clicks on the left, non-driver side (also reported by other users with motnhs onyl failure). 5NM retorque and grease, lasted 1 week. It is now unable to handle left power without clicking, and it is being exchanged for ceramicspeed.
Evidently not all these are created equal, and we must separate the argument from pro advantages, including daily or weekly tuneups, new parts every 500 kms, versus us, whom intend to ride that product more than a full season. perhaps i got a lemno enduro, but i doubt it as similar forum failures, amongst strong riders, describe a nearly identical experience, months-only.
