Spin-1 resonances are among the states predicted by composite Higgs models and one expects them the have masses in the range of a few TeV. We focus here on models based on an underlying gauge-fermion description which predict QCD-coloured vector and axial-vector states as well as states charged under the electroweak gauge groups. The former can come as triplet, sextet and octet representation depending on the model details. All models considered have a colour octet vector state in common which can be singly produced at hadron colliders as it mixes with the gluon. We summarize here their LHC phenomenology and comment also on aspects relevant for future colliders.
