  Gauged flavor symmetries at low energies have been proposed in models of
dynamical electroweak symmetry breaking and fermion mass generation. The
massive flavor gauge bosons give rise to corrections to precisely measured
electroweak quantities. We perform a fit to collider electroweak data and place
indirect limits on such new physics. In particular we study several models from
the literature: universal coloron; chiral top color; chiral, quark family
symmetry; SU(9) and SU(12) chiral, flavor symmetry. The 95% exclusion limits on
the mass of the heavy gauge bosons for these models, at their critical coupling
for chiral symmetry breaking, typically lie between 1-3 TeV. We discuss the
robustness of these bounds with respect to changes in higgs mass, b-quark
asymmetry data, the SLD left right asymmetry data, or additional new physics.
