An elevator system has a suspension member for supporting and/or moving an elevator car and being guided and driven by a traction sheave of a drive unit. The suspension member is a cord or rope that includes a body made of a polymer and at least one tension member made of wires extending in the longitudinal direction of and embedded in the body. A thickest wire in the tension member has a bending stress σb in a range from 350 N/mm2 to 900 N/mm2 when bending the tension member about a minimum bending radius r, and wherein the bending stress is a function of the elastic modulus E and the diameter δ of the thickest wire, according to the equation σb=(δ*E)/2r, wherein the suspension member is run about a pulley having a minimum diameter D corresponding to no more than two times the minimum bending radius (D≰2r).
