I'm looking to use these rings for a project. Does anyone know the diameter of the large hole in the middle. They are 130mm BCD track bike rings. I presume it is a standard to sit on a lip on the cranks

I could pop down to the bikeshed with a ruler but it won't be the most accurate measurement...

That's probably better than me measuring a picture on the screen. Much appreciated ๐Ÿ™‚
