VEXpro CIM Motor Gears with Mounting Hardware - VEXpro 217-3416, This 13-tooth 20DP steel CIM motor gear from the VEXpro range reduces weight and rotational inertia of your gearbox. The teflon-infused ceramic coating greatly reduces the friction of the gearbox at the initial motor reduction where drag has the most effect on the system. For applications requiring a bit more torque without changing the whole gearbox, this 13t gear w/14t center distance (Rapid code 70-3159) will actually fit with the same spur gears as a standard 114-tooth CIM motor pinion to easily reduce speed and add torque.
