Comes with hubs that bolt to your original dual brake hubs, spacers, 12 11/16" long, 3/4" diameter axle. I slid my 35mm tubes in there and they fit really well.
You can tell it has old chrome and the hubs look like they could polish up nice and shiny. The brake lip is 2 5/16" across.
$130 with shipping. The box is heavy so shipping won't be cheap. That's why it's $130.
