I am 100% new to the dynamo world, and after unpacking it I was surprised how it behaves. I already googled and found out that some of my worries are "normal", but for some of the issues observed I didn't find explanation (or "it is normal" confirmation).
I am talking about just hub, I didn't build a wheel yet. I am holding/squeezing axle nuts at one hand, and try to turn hub body with the other.
When I hold hub at hand and try to turn it there is a lot of friction, there are distinct points (some like stop points) where hub feels click-in (there is not audible click). Far, far analogy but it resembles the rear hub somewhat -- there is also some friction and there are also some special points.
Friction in dynamo hub I have is much greater. Gathering from all "it is normal" I take my hub is not broken. Yet.
But there is more -- the rear hub movement is predictable, I turn it by hand, the hub has no inertia so it stays exactly when I stop turning it, in other words any point/angle is valid point/angle. With dynamo hub if I am less than midway between points it bounces back by itself. So there are only X designated points/angles at which it can rest. And as for friction -- forward turning is hard, turning it backward is even harder (at first I thought it is not possible at all).
So my question is -- is this "more" section above normal as well, or those are odd even in dynamo-hubs world and I probably have broken hub (or terrible quality one)?
