Shimano 3D71 generator hub- vibration at speed?
So I've got my wheel with generator hub put together. It's a Shimano 3D71 hub on a 20" rim mounted on the front of my Gold Rush recumbent. I've been running around during daytime hours and I can't feel the resistance (which was my original worry- see this thread: http://www.bikeforums.net/showthread...ight-good-idea
). However, it has an audible and tactile vibration at high-normal riding speed, about 20mph (equivalent to 30mph on a 700C wheel).
Is this normal? Anyone else encountered this?
(I'm still getting my commuting setup put together. My work has showers- but they've been out of commission for the last couple weeks. You don't want to be around me if I haven't showered after a ride.)
Comcast nuked my web page. It will return soon..
