If R-parity conserving supersymmetry exists below the TeV-scale, new particles will be produced and decay in cascades at the LHC. Methods for determining the masses of the particles in the cascade from endpoints of kinematical distributions will be discussed. The emphasis is on the benchmark point SPS 1a, but scans in the mSUGRA parameter space can identify the region where this method is applicable. Analytic formulas give the masses in terms of the endpoints. A Linear Collider measurement can improve dramatically on the precision of the masses obtained.
