Well in fact, I will not need to try with another wheel. As I was riding

started to slow me with a drag similar to slightly pulling on the
brakes.

That definetely comes from the front hub. When turned, the wheel slow
down to a halt in less than one second, even with the brakes wide open,
and while nothing is making any noise that would suggest a friction from
somewhere else.

I will try to service the dynamo hub, before considering buying a new
one.

Thank for all the advice!

I haven't seen a dyno-hub in forever. So perhaps the newer ones have sealed bearings and that would make it easy to repair. I'm sure that you could find the service manual on-line.


That would be wrong.
Yes, Sturmey Archer classic DynoHub GH6 loose-ball hubs are
easily serviced. Many modern inexpensive designs with
sealed cartridge bearings range between daunting and
unreasonable for bearing service.
