Or maybe something in the hub isn't tight enough that is allowing the terminal 
to rotate

1. Open QR
2. Rotate the wheel so that the hub's terminal "outlet" faces the ground, then 
re-close the QR. That way rain water drips off and doesn't get guided to the 
outlet like it would when facing upward. Be sure to let a little bit of a wire 
loop hang down for the water to run off. And , maybe it will stop rotating to 
boot!

I have the same hub on two bikes, including my commuter, and I agree with 
you that it can't be moved by force.  I'm similarly flummoxed, and mine 
never moves on its own.  Maybe somebody monkeyed with your bike while it 
was parked?  Wanted to steal your front wheel, undid the QR, realized the 
wheel was locked and gave up.  Is that possible?  That would be an Occam's 
Razor answer.

Eric,  thanks for the reply.  The quick release was my first thought as well.  
I've made sure it's tight.  I think the mark around the quick release axle nut 
is due to this one being smaller in diameter than the last. This is the quick 
release the Riv folks sent with the hub, it's quite nice. The last one I used, 
that resulted in the loss of paint on the drop out, was larger.  When I try to 
manually rotate the connector back toward the fork blade, it does not move.  
I'm completely flummoxed!

Re: [RBW] Mystery Science Question

2016-01-28 Thread Kainalu 
Can't imagine why that would spin. I have two bikes with Shimano dynamos, no 
problems. Anyways, I'm questioning someting that was said earlier, about 
preferred locations for the connection. Is having the connector facing down 
better for waterproofing? Seems like the cap would then become something of a 
cup, with water wicking in the seam fairly easily. With a tight enough fit to 
the squishyish wires, wouldn't an upright connector be less likely to let it 
through? And farther out of harms way if you're doing any root hopping or bike 
rack parking as well.
Being fairly new to making my own electricity I haven't had to do anything with 
either hub. Been charging through a lot of puddles lately so I suppose it's 
only a matter of time...
Thanks

The vibration theory is really intriguing. I've rotated the connector around so 
that it faces "down" as suggested and will see if it continues to move against 
or with the hub rotation. I can confirm plenty of rough street input to the 
fork as I commute, so if the road vibration is a driving factor, I wonder if I 
can find a null point where both directional forces are equalized?  The mind 
does wander commuting on frozen , dark streets.
Thanks for the interesting input.

Matt:

Have you tried putting the old skewer back in? 

FYI, one of my SP hubs is held in with a older-style QR skewer, the other with 
a threaded type that requires an Allen wrench. No movement on either one over 
thousands of miles of riding.

Re: [RBW] Mystery Science Question

2016-01-27 Thread Eric Norris 
I have SP hubs on two bikes, and have never had this happen. Are you sure the 
quick release is tight enough? I'm not sure why the connector would rotate 
backwards like this, but that's the first thing I would check.

I'm also concerned that your front wheel isn't sitting in the fork ends 
correctly. Based on your photos, it looks like it's a few millimeters out from 
where it should be. I'd look into that as well--perhaps the springs on the 
skewer are somehow preventing the wheel from fully engaging in the fork ends, 
which might have something to do with the rotation?
