The GM10 Wheel works very well with the GM10 gear motor.
Simply snip off the self-centering tab on the GM10, unscrew the stock arm and spring, and replace them with this wheel to make a zippy wheel and motor combination!
It measures 25mm (1") in diameter, 5.7mm wide (.22"), and uses well-proven traction-band tires.
Each wheel comes with two small black traction bands (total weight: 2 grams)
Size: 2.5 x 0.6 x 2.5 cm
