These spacers arrived and looked very good. I put them on and they didn't seem as tight to the hub as they should be. But I thought everything would be fine. After a few rides, I noticed my wheels wobble at around 45-50 mph. But I just bought new tires and found they are. Removed the spacers and the noise was gone. These spacers aren't actually hubs and will make your ride terrible. I may have gotten a bad batch, but the manufacturer should have better quality control on something like this. I'm just glad my wheels didn't fall off
