  We consider an extended gauge group for the electroweak interaction: SU(2)_1
\times SU(2)_2 \times U(1)_Y where the first and second generations of fermions
couple to SU(2)_1 while the third generation couples to SU(2)_2. Bounds based
on precision observables and heavy gauge boson searchesare placed on the new
parameters of the theory, and the potential of the theory to explain R_b and
R_c is explored. We investigate processes that could produce observable signals
at the LHC and NLC.
