for racers, it seems like drag would be a serious issue. so if what this person is saying is true, why wouldnt more competition track hubs have loose bearings?
new dura-ace hubs (7710) are loose ball. i reckon campy pista hubs are as well. i can't say anything about the older shimano high-flange (7600), but i can't imagine they'd use cartridge bearings either.
