I have had this derailleur on two different bikes and it doesn't seem to be happy with the cassette I am using. For those unfamiliar, this is the "Downhill" specific version of the derailleur that is intended to be used with a narrow range cassette. As you can see, the B screw is backed all the way out and isn't getting close enough to the largest gear, and hits the frame on the smallest gear. The stopper is also fully pressed against the derailleur hanger. The easiest solution may be to just get a wider range cassette, but this is technically a correct cassette to use with this derailleur. Has anyone else experienced this? It's not the end of the world to get a new cassette, but it was described as being able to handle a narrow range cassette.

Your UDH is rotated. Loosen it up and rotate the hanger clockwise (looking at it from the drive side)
I’ve set up and ridden quite a few bikes with zee and saint drivetrains, the B-tension just doesn’t get that close, the shifting will be fine anyway. Generally I set it as close as I can and it’s fine, just make sure your chain is sized correctly and the derailleur clears the frame.
