BHV,
My son has a hoyt banshee. Im not sure exactly how long they bolts are but I do have his backed out quite a ways I measured the threads I have showing to where the bolt enters the riser to the bottom or the backside of the limb bolt it measures 7/8. I don't know how much more I could go without taking the string and cable off and actually takeing them all the way out.
I hope this helped.
