@Initium Thoth, thanks for the input. Yeah I thought the sprocket looked small also. It’s a “cassette” hub. They can have just tiny sprockets, because the freewheel mechanism is moved to the side, at least that’s how I understand it. And yes, there will be chrome.
Okay, I’ve turned on cycles, and started poking at materials. Material nodes really are my weakest point, mainly because I usually don’t go there. 
As an illustration, I brought in a DAZ model to show where it’s going. The character I’ve got in my head, is more stylized and cartoony, but this should atleast illustrate my intended direction.
I realize after getting a slightly more better material on the rims… They suck! Gotta go back and rework the topology around the nipples, and the valve stems are too small. But I did rework the sprocket, and for the most part am happy with the design, though it still needs to be finished. Started fleshing out the seat. It’s still just a mess, so we won’t look at it, Okay?
