Well, not in every case.
Very nice hubs, they can cope with the best cup & cone hubs out there.
But - Shimano loved to deliver new hubs that were adjusted a lot too tightly. The result is that they roll really well when they're new, but they cease to be new after amazingly few miles.
So do yourself a favor and check the hubs for adjustment (and maybe even give then a good grease-over, because Shimano was very "tight" on grease).
