Looks like a lot of it was like my weekend- with trails and not so much gravel as mtb trails.
To that end, I just pulled apart my rear wheel, and all good hubs evidently go to heaven.

Rear axle snapped and I didn't even know it, and that's a good thing as I was cruising 40-45mph in some parts.



I pulled the rear rim off to see about a small pinhole in a tire and these are the parts that came loose.
