Have you checked it in a truing stand and not just sitting in your fork? These types of wheels and the hubs themselves are notorious for being finicky and everything having to be perfectly right in order fo them to roll very true (true by eye and relativey true by stand stand). Not sure if its possible on your model as I cant see it clear enough, but I have had issues with some of these wheels not running right due to the end caps/covers not sitting right.

I doubt he sold you a bad wheel, unless isuess were disclosed up front. It doesnt make sense that he wouldnt respond. Also keep in mind that hop in the wheel could have come from shipping as well, and not been there before Brian sent them. Wa the packing sufficient, and the box intact with no damage when it arrived? In your video you said you werent able to get them on a smooth road to find out immediately after purchase....what type of time frame are we talking about?

You have kind of played a BIG card here, and then added that you've just only started. It is pretty obvious you're mad, but if every attempted contact has been angry and accusing that may be what is preventing you from getting your desired result, especially if the issue was discovered quite a bit after the initial purchase. With your post you don't give him much reason to work out a solution with you. You've done the damage already, and made the threat of doing more, that might not be the bet way to work towards your desired solution. Maybe try recontacting him and being coordial and laying blame elsewhere if you havent tried that already. Awknowledge that there could have been a damage during shipping issue or anything else and that you just want to work things out amicably.
