S3M Timing Belt 129mm, 43T, 4mm width

Timing pulleys and belts are the best way to transmit power from your motor to drive wheels or a spinning weapon. While O-Rings and round belts will slip under tension, timing belts have teeth that ensure a positive lock to the pulleys. A range of thirty-two belt sizes allows you to design your robot then pick a belt, rather than the other way around!
