We study the D=5 Emparan-Reall spinning black ring under an ultrarelativisticboost along an arbitrary direction. We analytically determine the resultingshock pp-wave, in particular for boosts along axes orthogonal and parallel tothe plane of rotation. The solution becomes physically more interesting andsimpler if one enforces equilibrium between the forces on the ring. We alsocomment on the ultrarelativistic limit of recently found supersymmetric blackrings with two independent angular momenta. Essential distinct features withrespect to the boosted Myers-Perry black holes are pointed out.Comment: 15 pages, 2 figures. v2: added multipole expansions at spatial infinity, and a comparison with the boosted Myers-Perry solution in a new appendix.
