I received a Cosmic Carbon 40C from a customer.


The centering was nearly perfect and the wheel runout was minimal,
so the work wrapped up quickly.
The front hub had a grinding sensation when spinning,
so I thought the bearings might be shot,
but it turned out the ball bearing race adjustment was just over-tightened.
I was thinking it might be unnecessary since it has a contact seal,
but I went ahead and greased it anyway.
