DH-3N20 bearing adjustment
What's the conventional wisdom for setting preload on
Shimano hub dynamo bearings?
On a normal hub I'd adjust the cone finger tight and
set the locknut without moving the cone. The dh-3n20
hub is quite a bit more limber owing to the diaphragm
like ends.
If more preload is needed, how much?
Thanks for reading,
