Very cool wheel! Do you have the resources to fabricate these or are they just a thought exercise?

I'm also curious about what features you've designed into it to make it more optimal for a chain drive?

With regards to custom wheels, here are my opinions on them:
Custom wheels aren't something you do because they'll save you time. They're something you do for the journey along the way-- the experience of designing and manufacturing them. They're a mountain that you climb because it is there. With modern COTS wheels, there just aren't very many situations where custom is a competitive advantage when it comes to wheels. This makes them perfect for an offseason project.

With regards to your questions, I'd ask how these compare to your targets-- are they cheaper than comparable COTS products? How much better are they for chain? Did you achieve your goals? If not, how can you reach them?

Best of luck with your project.
