I actually think that it may not be inside the rim now.

I pulled the tire and rim strip and shook and beat it. It was rolling quiet in my hand. I reinstalled everything and it was fine.

I rode it around the block and the noise is still there. It's louder the faster I go.

So yeah, no spokes loose or broken although this is pretty much what it sounds like to me.

The wheel seems structurally great, bearings and cassette body seem fine. I am only hearing this while I'm on it. So my weight is throwing something off (I'm only 138, so I'm not crushing it). The question is what.
