Yes, I had assumed loose caged. The Scuzzy Logic (threadless) is sealed cartridge. Unfortunately, the 1" are becoming harder to find. I think there may be some advantages of sealed cartridges, at least for the lower bearings. And a minute amount of friction from sealed cartridges is of little concern.

Anyway, the Campy is nice for a "vintage" build, but there may also be better headsets available.
