A customer brought in a Racing Zero wheel for service.

The customer rode in with this wheel already installed,
but the front hub had noticeable play in it.


The play was pretty substantial, so I disassembled it and found

one of the cone races had slight pitting, so I replaced it.
The hub shell itself was fine, and though it's hard to visually inspect being USB-spec,
I didn't see any issues with the bearing balls in the retainer,
so I cleaned and greased everything back up, and reassembled it.
The feel returned to normal.


Both wheels had noticeable runout, so I worked through it carefully.
The front wheel had built up a false center before I touched it,
and the wheel truing actually shifted that, so I've been making corrections all over the place.
