We propose rare decays of Zf1f»2V (with V=WorZ, and f1,2 ordinary fermions) as diagnostic tests for gauge couplings of possible gauge bosons at future hadron colliders. Because of the collinear singularity such decay rates have a logarithmic enhancement proportional to In2(MZ2MV2). For MZ1 TeV and a large class of models, there would be a sufficiently large (> 102) number of leptonic and semileptonic events at projected luminosities at the CERN Large Hadron Collider and Superconducting Super Collider. A discussion of backgrounds and a comparison with the forward-backward asymmetry are given.
