Yeah, my DA 7600 hubs were nice when new. But, they require maintenance and tuning after a couple of years. When they get a lot of miles on them or the grip nuts get mashed-down, the tolerances get wonky and you'll have a number of issues.
For worry-free use, use sealed hubs, as
topflightpro suggests.
