The sound I am hearing is much higher pitched than in the video. The video sounds like a rattle, mine sounds "chirpy". It ONLY occurs between 4500-5500 RPM, no matter what speed I'm traveling at. If the revs are any higher or lower, the sound immediately stops.
If it is being caused by the chain, what is considered to be excessive variation in the chain tension?
There is no sign of any wear or marks on the chain guard.
Besides the sound I am asking about here, I am also hearing a rubbing, grinding noise from the front wheel. I have had the calipers apart, and everything looks OK there. I understand that if a disk was warped, I would feel excess play in the brake lever on the first pull, and the brakes seem to work fine, no throbbing or slipping, nice and smooth. I have seen threads in my research online that say that a noise like I am hearing from the front wheel can be caused by the front axle bolt being over torqued, putting pressure on the bearings. Any thoughts on this?
