1. A method of manufacturing a suspension member, the method comprising:
providing a first set of yarns and a second set of yarns;
combining the first set of yarns and the second set of yarns to form the suspension member;
tensioning a first portion of the first set of yarns and the second set of yarns to a first tension;
tensioning a second portion of the first set of yarns and the second set of yarns to a second tension that is different than the first tension; and
at least partially bonding the first portion of the first set of yarns and the second set of yarns together by heating the suspension member to form a first zone of the suspension member having the first tension; and
at least partially bonding the second portion of the first set of yarns and the second set of yarns together by heating the suspension member to form a second zone of the suspension member having the second tension.
