This is the same wheel used on the ActivityBot. Purchase one as a replacement or more for your own robotics project. It fits most servo hubs (but not Hitec). The wheel has 32 tiny holes between its "spokes" making it a good choice for use with a wheel encoder setup.
The O-ring tire stays in place securely between staggered tabs along the wheel's edges.
