Buddy of mine sent me a used headset for my backup bike, but it's very dirty.
I'm used the sealed bearing kind and you don't clean em.

This one is not sealed ... it's a RaceFace ... it's an open style, but I'm not sure the bearing will pop out of the cup ... did not look like it at first glance.

Like to clean and regrease before installing.
Suggestions?
Thx
