A recent suggestion that quantum gravity becomes strong near the weak scale can be probed by the exchange of Kaluza Klein towers of massive gravitons in fermion pair production in e{sup +}e{sup {minus}} annihilation and in Drell-Yan production, including contributions from gluon-gluon fusion, at hadron colliders. These processes are found to provide strong bounds which are essentially independent of the number of extra dimensions. We also demonstrate that angular distributions provide a smoking gun signal for low-scale quantum gravity which cannot be mimicked by other new physics scenarios. {copyright} {ital 1999} {ital The American Physical Society}
