Supersymmetry is one of the most popular theory to be tested at the LHC. In order to obtain predictions for the spectrum of supersymmetric particles, we need to understand SUSY breaking and its mediation. Combining gauge and gravity mediation is a way to address the flavor problem as well as the generation of the electroweak symmetry breaking. I will present a model in which this scenario arises simply, with an extra experimental signature. The neutralino, mostly bino, is lighter than the rest of the spectrum, and becomes the LSP.
