Hello everybody,

I just received in the mail what is my first dynamo-equipped wheel, built on a Sanyo H-27 hub. When I opened the box and spun it in my hands I was greatly disappointed to find that it feels like crap: the rotation is so "bumpy" that it only spins for a few seconds before coming to a halt and I'm almost certain that I'm going to feel the vibration through the frame once the wheel is mounted. I know this is a low-end dyno-hub and it's not going to spin as well as a Schmidt or a good Shimano one, but is it really supposed to be this bad? Can this hub be adjusted in the same way that a conventional cup-and-cone one can? Or did I waste my money on a lousy wheel?
