SON hub dynamo

[Fergus Flanagan]

Just got my brand new 20in wheel with built in SON hub dynamo for my StreetMachine hmmmm! I have
noticed as I try to spin the wheel holding it in my hands it feels very very notchy and assume this
is the magnets, i didn't expect this, is this normal? Does it disappear with speed as it feels there
is alot of resistance when i spin it slowly. I was expecting it to spin quite freely at any speed
but until i mount it on the bike, I guess i won't really know if the notchiness or resistance
disappears. Has anyone else experienced this?

Yes it is normal.

I can not tell the difference between my SON hub and a regular hub once it is on the bike
and moving.

Note: The drag is barely detectable. Put it on the bike and forget about it.

It shouldn't be *very* notchy - mine runs fairly freely as long as the light is off.

I think maybe as i am only spinning it in my hands slowly the notchiness is more apparent and as
Cletus pointed once it is on the bike all will be sorted. Thanks guys
