I'm trying to get my Wheel onto Sketch fab but the materials aren't carrying over properly

I used the node editor to mix a Diffuse and a Glossy BSDF shader for each of my materials, but when I upload the model on Sketchfab everything is the neutral grey color.  I'm using cycles as my render engine and I also set up an image background but I'm mostly concerned about getting the materials across the transition, I could take or leave the background image.  What step am I missing here?
