Alright then; I expect I had just never heard of this break in for hubs -- and thinking about it feels a little odd: what precisely is there to break in between hardened steel parts?

But no matter. I am glad to have unwittingly preemptively followed best practices by setting the initial adjustment just so and revisiting it after a few hundred miles.

I'm rather curious to see how far these hubs can go with plenty of TLC and copious amounts of fresh lube and balls.

Thanks for your help Andy.
