I've had a Alfine dynohub for about 1 1/2 years now.I love the thing BUT it has developed a noise in it.It has about 12,000 miles on it.
Riding around with the lights off,silent.Turn the lights on,it starts making noises.
Turn the lights on and spin the wheel by hand....forwards,makes noise....spin it backwards,no noise.
My guess is that a magnet has dropped/come loose and the magnets leading edge is dragging making noise in one direction but not the other.....That's the only thing I can think of.
Anyone else have any issues like this.......
