Thanks, I am hoping for one of the black more modern sport ones that does not need pins. The Comfort one I have and could swap, is one like that.

I also have one of the first adjustable comforts [the type with pins] but looking at it, it looks like a really early model, they way it meshes with the headset.

Pins can be obtained from the German Citroen 2cv supplier I posted on another post. I had forgotten that they work on a Birdy and they are still for sale.
