Staral 20 x 1 3/4 (1.75) rim with Faded red Sunshine hub. Spins well. Need repacked. Fair true wheel, no flat spots. I'm guessing this is a late 70's BMX wheel, but have never heard of Staral. I don't remember these square hole Sunshine hubs either. I don't know how rare these rims are so my price could be off. Some yellow spray bomb inside of rim. I gave it a quick shot of remover and it comes off very easily.

Rim: Aluminum, raw aluminum. 20 x 1 3/4"
Hub: Faded red Sunshine, high flange, slotted axle. Spins well, has not been repacked.
Weight: 1 lb 14.25 oz
Spokes: Most are straight, slight oxidation.
Nipple: Chrome steel, in good shape.

The rim is true. Smallest hop (1/16"), side to side is straight. Rim has no flat spots I noted.
