Even with Aluminium pulleys, which probably are a little heaver than roller chain sprockets, the huge reduction in weight by switching from a steel chain which weighs about 240-360g to a belt which weighs <100g more than compensates.
The belt consists of carbon fibre tension cords enclosed in a rubber outer casing.
