Your message reminds me of something I heard a few years back. While I don't remember all the specifics, the general idea is this:

Sometime in the mid 1990's we received a letter at the LBS where I worked that idicated Phil Wodd hubs were being counterfeited somewhere in Asia. I'm fraid that I don't remember much else, other than that the message said the bogus hubs were pretty easy to identify. In any case, this was later than the era of your difficulty with flange failures, but it's interesting nonetheless.

I humbly differ. Check out Sutherland's comments on cartridge vs. cup & cone hub bearings. Essentially he says that radial bearings, as foud on most cartridge-bearing hubs, are good at supporting radial loads but lousy at supporting axial loads. If the bearing is preloaded enough to eliminate play at the rim, it is only because the inner and outer races are shearing the balls. Failure quickly follows. A properly set up Phil, or MAVIC, or what have you, will have play at the rim. While I find such play annoying, it is not so terrible, but with a "conventional" hub this play is unnecessary. I give Shimano a great deal of credit for sticking with a cup and cone design on this particulay bearing. It looks like Campy has switched over to cheaper-to-produce generic cartridges, at least on the top-end stuff. I further give credit to Shimano for knowing where to apply cartridge bearings. Specifically, at the BB where the load is almost completely axial. In addition, they have done a good job at replicating the oblique bearing geometry of a conventional headset within a disposable cartridge.

As for the notion that cup and cone hubs are easily contaminated, such is simply no longer the case. Ride a Dura Ace or XTR hub for a year, open it up, and tell me what you see. These hubs are no more easily contaminated than most cartridge models, and far easier to clean out if they are.
