Observable signatures of composite vector bosons W/sup */ and Z/sup */ at e/sup +/e/sup -/ and pp-bar colliders are discussed. W/sup */ and Z/sup */ introduced as matter fields in an (effective) SU(2)/sub L//sup loc/ x U(1)/sub Y//sup loc/ model satisfy a mass relation of m/sub W/m/sub W//sup */ = costheta m/sub Z/m/sub Z//sup */ instead of m/sub W/ = costheta m/sub Z/. Constraints on W/sup */ and Z/sup */ arising from low-energy weak-interaction phenomenology set limits on deviations from the standard-model predictions and on production cross sections of W/sup */ and Z/sup */.
