I understand adjusting the cones on conventional hubs, but I have no experience with sealed bearing hubs. Is it worth trying to replace the bearings, or replacing the hubs? Or is it time for new wheels? How good are these Wolbers anyway?
“Sealed bearings” doesn’t necessarily mean that the bearings are cartridge bearings. Shimano hubs are usually marked as “sealed” and they are all loose bearing hubs. They do have labyrinth seals and rubber boots that seal them against the elements. Cartridge bearing hubs seldom develop any kind of play since the bearings are usually pressed into place and can’t really move side to side. The axle just can’t move.

Huh? There are several thousand suppliers of hubs around the world. There are several thousand more if you include the ones that are no longer in business. There is no reason to think that the hub in question is a branded Specialized hub in particular.
