  We compare the sensitivity of precision measurements of lepton flavour
observables to the reach of the LHC in a case study of lepton-flavour violating
operators of dimension six with two leptons and two quarks. For light quarks
precision measurements always yield the more stringent constraints. The LHC
complements precision measurements for operators with heavier quarks.
Competitive limits can already be set on the cutoff scale $\Lambda$ > 600 - 800
GeV for operators with right-handed $\tau$ leptons using the LHC run 1 data.
