I received a set of 7900 tubeless wheels from a customer.


They've been used for about 18,000 km.
Even though there weren't any particular issues or problems,
the customer requested I inspect the hub internals
and adjust the runout and centering.

The centering was only slightly off on both front and rear,
and the fine runout was
the type that disappears almost entirely with single-sided truing.

The front hub's bearing balls were in good condition
and the ball races were clean, so
I just handled it with a regreasing without disassembly.


The rear hub was dirtier than the front, so I disassembled it,
but it didn't have any major issues either.



While I was at it, I also cleaned the sprocket.
