These pulleys may be used as part of a power transfer system or a gear reduction system. Simply cross the rubber band over to reverse the rotation direction. In addition to the three types of pulleys, axle bushings are also included which are compatible with 2mm and 3mm hex shafts as well as 2mm and 3mm round shafts. A 1m long rubber cord as well as normal rubber bands complete the set. Set your creative spark to work and use them to power your own unique Educational Construction projects!
