Implications of a gravitational fixed point at high energies are worked out using Wilson's renormalisation group. We find that relevant cross-sections involving virtual gravitons become finite. Based on gravitational lepton pair production we conclude that the LHC is sensitive to a fundamental Planck scale of up to 6 TeV.4 pages, 3 figures; v2: error in numerics corrected (Tab. 1), typos removed; v3: comment added, version to appear in Phys.
