Noise of 9C from Italy in each turn

Postby ecologymagnet » Sat Aug 18, 2012 4:43 am

I have a Nine Continent RH205B with +-1000 miles, it run at 20S 45A.

The wheel emits a noise in each turn "CRI CRI CRI" when I go at low speeds <15 mph on the bike, the noise seems come from the spokes, but I screw the spokes but the noise continue.

The noise doesn't come from the pedalier or seat.

Have Someone a idea about the origin of noise?, How can I solvent this noise?

Thank you.

Quite a few possibilites. The two most likely are a scrap of insulating material is scraping the cover, or a wire. or you could have a bad bearing that is allowing contact of the stator and the rotor.

It could still be spokes, but that generally makes a sound you do recognise as spoke noise. At that level of overpowering, you could get spoke noise that won't go away unless you overtighten them, and don't do that. You are after all, putting a few hp into a bicycle wheel. My dirt bike wheel running 20s 40 amps always talks a bit, when I lean it hard into sharp turns trying to taco fold the rim. After a hard ride, It may ping and creak more than it did at the start of the ride, and I do have to keep re tightening that wheel every six months or so as I keep stretching out the spokes.

Do you have a disk brake? Could it be a rubbing noise from the disk?

It may also be a bearing.

Finally today I screw the spokes losses and the noise disappear.

Thank you.
