stands for International Bowhunting Organization. if you mean IBO speed that is what the bow industry measures their speed by. they set the bows at 70lb, 30 inch draw, shooting 350gr arrows and i think a single nock on the string. the speed they get with the bows set like that is the IBO speed. after your bow is rigged up for hunting, with probably diffrent draw legnth and weight and arrow weight, and stuff on the string you loose speed from the IBO speed. generally 30-60fps. usuall around 40-50fps unless you have a really short, light draw or super heavy arrows or bricks on the string lol. hope this helps..
