hi i am just seeing what the interest would be if a had a middleburn bashring re-created from scrach it would be 20t size and it would have the back cut out enough for a bmx chain to fit, the front will be like a cone going in to the center with slots drilled out of it instead of the radieoused (sp) on normal middleburn bashrings this would allow more flexibility if u do want to mill it out.
depending on the tooling cost at the factory i was thinking of around £20
this would be a bashring milled from a solid billet of aluminium NOT a middleburn bashring milled out
please post your interest and i wil see what i can do
