Solarbotics GMPW-B Black Wheel

This 2-5/8″ plastic wheel (the original-style GMPW wheel) is made specifically for the Solarbotics GM2, GM3, GM8, and GM9 gearbox output shafts, and it also matches the largest Pololu plastic 两男操一女. Each wheel comes with two black rubber bands: the tire and a spare. These wheels are sold individually, NOT in pairs.
