We present numerical evidence for the existence of a new type of black hole solutions with a nonspherical event horizon topology in d>5 spacetime dimensions. These asymptotically flat configurations are found for a specific metric Ansatz by directly solving the Einstein equations with suitable boundary conditions. The new black holes are regular on and outside an event horizon of S2× S2k+1 horizon topology, being supported against collapse by rotation. Numerical solutions are constructed in a systematic way for d = 7. We point out that the basic properties of the new solutions are very similar to those of the d=5 black rings. In particular, one finds two branches of solutions, which branch off from a cusp. Moreover, for a range of the parameters, there are three different solutions with the same global charges –two black holes with S2× S2k+1 horizon topology and one Myers-Perry black hole.
