One of the main physics goals of the Large Hadron Collider is the search of particles predicted by supersymmetric theories. This study analyses the possibility of using kinematic endpoints of mass spectra for a sparticle mass reconstruction. It focuses on cascade decays, which include the second-lightest neutralino, in the mSUGRA framework with tan(b) = 35, A0 = 0 and positive mu. A region of 25 points around the benchmark point I' with m0 = 181 and m1/2 = 350 is chosen, where the cascade decay of the second-lightest neutralino into two opposite-sign taus and the lightest neutralino has a branching ratio of over 95%. Two methods of measuring 13 kinematic limits are tested systematically at Monte Carlo generator level.
