I just changed my tires and during the test drive I notice a very weird feeling/sound around 17 ± 3mph. It almost feels like something rubbing, but I certainly can't find anything obvious. It does not matter if I use front brake, rear brake, or coast in any gear (including neutral). It seems more noticeable on the way down. I don't know if that is because the engine is revving while speeding up or if this is the nature of the problem. Alignment is as close as I can make it. I think the chain itself is fine. What the hell could I have done? The only other thing I could think of are the wheel bearings, but the seals looked good and I could spin the inner races with my finger just fine. I'm hoping I just forgot something stupid, but I'll take any ideas I can get. Thanks!
Almost forgot. I noticed it before I did anything to the front, so I am pretty sure it is the rear.
