2004 Bianchi Vigorelli with about 2000 miles on it. The Cosmos wheels are stock.
The rear wheel is "dished", and the spokes on the left side seem to be not quite as tight as the spokes on the right. The wheel is very true. Anyways, the rear wheel is creaking. It will only do it with some weight on the bike. If I lay my chest on the saddle and roll the bike back and forth I can get it to do it a little bit, but you can definitely hear it pretty good while riding. I can't tell exactly what is making the noise, but I suspect it's the spokes. I was going to try and tighten them up a little, but I'm afraid of pulling the wheel out of true. I can usually true up a wheel half decent if it comes out of true, but I'm not an experienced wheel builder by any means, and these wheels are expensive, by my standards. Besides, some of the spokes are pretty good and tight, and I don't want to overtension those spokes. The way I figure it, if the wheel is true, and I tighten a couple of spokes, I pretty much have to tighten them all. I'm very happy with the wheels, I'd just like to get rid of the noise.
Is there anything else that anyone can think of that might make a "creaky" noise back there?
I don't really have a good, reliable bike shop around here that I would trust to take the wheel to. Any advice?
Thanks in advance.
