  We have analysed the observable consequences of the interactions of spin-1
resonances coupled to the invariant fermionic currents that arise in an $SO(5)$
Composite Higgs set-up. The phenomenology entailed by such interactions is
thoroughly analysed by studying heavy vector resonances production and decay
modes in the viable resonance mass range. Additionally, the production of
double and single-composite fermion final states has been scanned along the
fermion mass scale. Such production is mediated by the SM gauge and Higgs
interactions, and also by charged and neutral vector resonances. The coupling
between the new fermions and vector resonances induces a sizeable effect in the
production rates. We use the recent 13 TeV LHC searches for vector-like quarks
to constrain our parameter space. Specifically, we explore the allowed regions
by analysing the decays of a heavy vector-like quark in the $Wb$-channel. We
conclude that generically the impact of the couplings between the spin-1 and
spin-1/2 resonances will substantially reduce the permitted regions, leading us
to test the sensitivity of the parametric dependence in the light of exotic
matter interactions.
