I-Sverical Breings, ekwabizwa ngokuba ziibheri ezidibeneyo, zizinto ezenziwa ngamatshini ezenzelwe ukuba zihlalise i-angland mpungutho kunye ne-oscillating okanye ijikeleza intshukumo phakathi kweenxalenye ezixhunyiweyo. Ngokungafaniyo nebhola esemgangathweni okanye i-roller brabys, zibonisa umphezulu woqhawulo-mtshato (umsesane ongaphakathi) othatyathwayo ngaphakathi komsesane ongaphandle. Olu luyilo luvumela intshukumo kwiindlela ezininzi ngaxeshanye.
