I know Milwaukee frames have this option and I absolutely love the aesthetic it gives.
When I first saw this I was thinking about making my own custom frame badge. But back in the day I had very little way to go about it.
I now have ability to make some high quality parts. I was wondering how many people would be interested in buying a frame badge.
Now its would be unpractical for me to produce these in metal. However, mass producing these in plastic would not to be that hard. Also means they would be easier to paint and allow more customization.
The frame badges would be made to fit 1 or 2 standard diameter tubes. And would probably be required to be epoxy on. (Other than water bottle bosses not sure how else it would adhere).
Now these wont be some handmade pieces of crap. They'll be 3D printed and very clean. Also due to the cost of making the original parts I can only make one or two different words/phrases. Possible badges; "Hipster" "Fixed Gear" "Track Machine" "Tarck" "Tarckster" "One Gear" Not really sure what to do yet, but if you have any ideas feel free to add them. Could even be uncommon things like. "Bombs Away" "Common Sense" "Chocolate" "Flight" (If I like it, I may potentially send a free badge.)
So again after all that the question is would you be interested in a frame badge? And if you are, the price range you expect these to be.
