This 25mm (1") diameter is custom made to mate with the GM10 pager gear motor. Ideal for Micro-sumo robots!
The GM10 Wheel works very well with the GM10. 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)
We built the "MicroVore" micro-sumo robot with this setup, and it placed 3rd at PDXBot04. It was a bit too fast and squirrely, but still not bad for a first time in competition!
Wheels sold individually. Motor not included.
