Mack hubs are awesome. I think this guy/girl in Poland machines them all by hand or something. They are so incredibly smooth. They look burly as hell, but they're surprisingly light. They spin so incredibly smoothly. The amount of detail in them is astounding (rescessed spoke holes, etc.) By far the best bike part purchase I've ever made. These seem so much nicer than the DA low flange hubs I was using.
Mine are 28h high flange, laced to Saavedra Featherweights with ovalized, aero spokes. So, so sweet.
Note: these are not my photos, I believe, they are from Mack, but I'm not sure. If they're someone else's, sorry and thanks.
