Based on my experience, they don’t “break in.” It has nothing to do with the bearings.
The notchiness is happening when super strong magnets inside the hub get close to metal parts—this is what makes the electricity. As the two approach each other, they attract and cause the “notch” feeling. Imagine holding two strong magnets and moving them vertically past each other. When the magnets get close enough, they’ll try to reach out to the other magnet—that’s what you’re feeling when the SON hub gets a little harder to turn. Here are the internals of a SON hub. You can see the magnets arrayed around the inside of the hub shell. So no, the hub won’t lose the notchiness. It’s built into the design. P.S. It’s always a good idea to tell this to the bike shop if you take in a SON hub or wheel. Some mechanics will think that the notchiness is in the bearings (it isn’t) and will try to “help” by adjusting them (they can’t, and it will void the warranty). --Eric Norris [email protected] Insta: @CampyOnlyGuy YouTube: YouTube.com/CampyOnlyGuy > On Apr 28, 2021, at 4:51 PM, Joe Bernard <[email protected]> wrote: > > Next question for this saga, for folks who know and ride these things: Do SON > hubs break in and get quieter as the miles pile up?
