Scrod, I have a Surly Ultra New Hub with Velocity Synergy rim. When I tighten the axle bolts (or put in a skewer) the hub goes from silky smooth to binding.

This is my first sealed bearing hub. Shouldn't the compression forces that clamp the hub axle in place be isolated from the sealed bearing as they essentially are in a cone and cup bearing?

How can I fix this?

Thanks
