>>1812635isn't it just about the viscosity in terms of grease?! my dt swiss 370 track hubs probably have pretty generic bearings but they spin incredibly smoothly probably because of how well they fit in the hub shell with the right preload. i want to try putting in angular contact bearings at some point but i'd have to spend money on the installation cylinders because there doesn't seem to be any good way to make a DIY bearing press for these track hubs.
