The rubber ring grips the stud on the micro motor. You can then use it as a
pulley or to connect an axle to the micro motor. They appear to grip tightly
enough that they never slip within the torque range of the micromotor. Don't
worry about ruining the rubber ring -- you'll always get a new pulley with any
micromotor.
The right part for a limited-slip axle connection is the white clutch gear.

| Unfortunatelly I don't have a clutch gear. It's hard to find and I can't order kits with it outside US. :( Pulleys and clutch gears can solve the problem but they requires more space.
