That's a good testimony, Rudi, and you have a bigger sample size than most of us do. Shimano hubs have a good reputation, but you've had problems with three Shimano hubs and no problems with two Sanyo hubs. I realize that sample isn't big enough to show convincingly that Sanyo hubs enjoy better reliability overall, but it's still interesting. So what's bad about the Sanyo? I gather it creates the most friction, but I have two, and I can't feel the loss as I ride. Sanyo hubs also can't be overhauled, and we can't even replace the cartridge bearings (as I understand it) but if it's not going to fail, what do I care.
