I just got a new wheelset with XT hubs (M756). The hubs are not turning very smoothly, in fact they're kind of rough. Is this to be expected with new hubs? I would think they would come almost perfect from the factory. I'm inclined to not ride them as they are since it seems it could damage the races. I'm thinking of taking them all apart and packing with some phil wood. I hate cup/cone adjustments and now wishing I got something sealed. I think XT hubs (bearing adjustments aside) don't measure up to quality of other XT components (crank, brakes etc).
