If I may comment, While there is no free lunch you do get the energy used in deflecting the frame back minus the hystersis-internal material friction-loss, which in metal is minimal but pretty high in rubber. The deflection attributed to rubber will be returned mostly as heat in the tires but the deflection in the frame will be returned mostly intact when you finish deflecting-when the sprint is done.
