I was surprised by the measurements of mine. 50 mm at the top, choke down to 40-41 mm in the middle, and open back up to 44 mm at the bottom. They may have been opened up at the head end.

I'm curious what a new set look like. I'm told they are 50 mm at the top and 42 mm at the bottom. I'm wondering what they measure in the middle.
