Dynamo hub cones regulation I have bought my first dynamo hub wheel with Shimano DH-3N72 hub.

The axle of the wheel fells like if it is over-tightened a bit, it rotates with feeling of clicks.

Should I loose the cones in the hub OR I am wrong and this is just magnetic forces inside a hub provide me such a feeling?
The feeling of notches is just the resistance you feel from moving the magnets past the coils in the hub.  That's what generates the power.  The hub is fine!  When you actually ride the bike you won't feel a thing. Well, at least I don't feel anything. Some people have said they feel vibrations from their dynamo hub at lower speeds.
