Belt offers more advantages over chain than just weight savings. They are slightly more efficient, they are cleaner, they do not stretch, and they do not require maintenance. We have used 24 tooth pulleys with 15mm HDT belt on both 4" and 6" wheels with 3 CIM single speed gearboxes for 4 seasons. We have never broken a belt. If you size your pulley correctly for the wheel and use exact center to center, you should only have to touch your belts one time, I can not say the same for chain.
