A roller shade comprising a shade drive unit having a counterbalancing spring connected to and extending between a stationary spring carrier and a rotating spring carrier over an output mandrel, wherein the output mandrel comprises a length that maintains the spring in a stretched state such that the plurality of coils at the active portion of the spring do not contact each other when the shade material is at the rolled down position to reduce friction in the counterbalancing spring.
