Centripetal force is the force exerted by the wheel rim on the balancing weight, pushing the balancing weight toward the center of the wheel. It's what makes the balancing weight following the circular path.

Centrifugal force is the reaction force exerted by the balancing weight on the wheel rim in response to the centripetal force. It is a real force.

So Ksafin's only mistake was that he should have said "centripetal force" instead of "centrifugal force", because he was referring to a force acting on the weight.
