We consider cumulant moments (cumulants) of the thrust distribution using predictions of the full spectrum for thrust including Oð 3 s Þ fixed order results, resummation of singular N 3 LL logarithmic contributions, and a class of leading power corrections in a renormalon-free scheme. From a global fit to the first thrust moment we extract the strong coupling and the leading power correction matrix element 1. We obtain s ðm Z Þ ¼ 0:1140 AE ð0:0004Þ exp AE ð0:0013Þ hadr AE ð0:0007Þ pert , where the 1-uncertainties are experimental, from hadronization (related to 1) and perturbative, respectively, and 1 ¼ 0:377 AE ð0:044Þ exp AE ð0:039Þ pert GeV. The nth thrust cumulants for n ! 2 are completely insensitive to 1 , and therefore a good instrument for extracting information on higher order power corrections,
