Sharp, squealing noise coming from low and back.
I have heard a really strange squealing noise, three times now, coming from somewhere under my seat and toward the rear of the bike. It doesn't last long enough to locate it's origin, as it only happens for a second, and only when cruising at a steady speed (like 40mph) on smooth pavement, but it's loud enough to let me know it totally not normal. It doesn't happen under acceleration nor when going over bumps, and I have not been able to replicate it intentionally by flexing the suspension or throttle. Since it happens at cruising speed I am probably in 4th gear, though I can't swear to that. It worries me.
The sound is a sharp, high-pitched squeal like something very tight slipping, but only lasts a second and does not recur for several minutes if at all, nor does it occur on every ride. The first time it happened I thought I may have imagined it, but days later it happened twice on the same ride, both times when doing nothing extraordinary, just loping along. Ideas?
