Abstract: We study consistent Kaluza-Klein reductions of type IIB supergravity onT1,1 down to five-dimensions. We find that the most general reductioncontaining singlets under the global SU2xSU2 symmetry of T1,1 is N=4gauged supergravity coupled to three vector multiplets with a particulargauging due to topological and geometric flux. Key to this reduction is severalmodes which have not been considered before in the literature and ourconstruction allows us to easily show that the Papadopoulos - Tseytlin ansatzfor IIB solutions on T1,1 is a consistent truncation. This explicit reductionprovides an organizing principle for the linearized spectrum around the warpeddeformed conifold as well as the baryonic branch and should have applicationsto the physics of flux compactifications with warped throats.
