Olympic bench press?

Hey does anyone know how much the olympic bench press's barbell weighs before you put any weight on it?

i think 45 lbs

Remember that Olympic weightlifting weight is measured in kilograms and that 1 kilogram = 2.2 pounds. The men's barbells weight 20 kilograms and the women's weigh 15. There are two full body lifts that make up Olympic Weightlifting. The Snatch and the Clean and Jerk. Bench pressing isn't an Olympic Sport just so you know.
