I'm full, couldn't eat another dick
I’d say yes. In unsealed, the cup is also the bearing race. In sealed, the bearing sits on the race...if you know what I mean?Question, that may or may not be stupid..
Background: Replaced forks and greased/reassembled headset (syncros unsealed bearing type).. the compression ring doesn't go in too far to preload the bearings, and the fit is very iffy (i.e 1mm gap between headset cover and cup in headtube, almost feeling like there remains some play within headset.. although that may be psychosomatic based on seeing a gap - the star nut and bolt are done up pretty tight too.. Anyway...
Ordered new headset with sealed bearings to hope it fits better.. Do I need to replace the headset cups?
