Johnny,

Everything you see in the photos is metal.
The one wheel I showed dissassembled is an Idler, they are grouped with the sprockets and Return Rollers (Silver Studs) in my photos.
The Sprockets in the photos are Metal.
They came painted...

Double check with Hobby Raw!!!
When I ordered the Road Wheels EVERYTHING you see in the Photos came with them EXCEPT the Idlers.

I had to order the Idlers Seperately...
