It's not what I would call thin-walled. As others have reported this does not fit my Zenik plastic hub rims. When the bushing is removed it will fit but touch the sides of the eyelet holes. This leaves marks on the discs. I might as well buy a regular 18mm thin wall outlet and use a 3 inch extension on it. Otherwise it's really good but for the price I have to send it back.
