I think I am going to stitch up a mirage band for the AE. Does anyone know what the thread pitch is for the threaded hole in the top of the brake? I can't find any reference to it in the manual. I guess I could pull off the brake and take it with me to the hardware store, but I am sure one of you out there knows it off hand.
