Zodziwika bwino ndi monga kapangidwe ka chidutswa chimodzi, kapangidwe ka zidutswa 5 kapena 6 (magalimoto oyambira kutumiza), kapangidwe ka zidutswa 7, kapangidwe ka zidutswa 8, kapangidwe ka zidutswa 9, kapangidwe ka zidutswa 10, kapangidwe ka zidutswa 11 ndi kapangidwe ka zidutswa 12 (magalimoto apamsewu).
Liwiro la 8, 9, ndi 10 likuyimira chiwerengero cha magiya pa flywheel yakumbuyo. Liwiro likakwera, unyolo umakhala wocheperako. Chifukwa ma pedal onse a njinga zamapiri ali ndi ma chainring atatu, ngati flywheel yanu yakumbuyo ili ndi eyiti, zikutanthauza kuti chiwerengero cha ma chainring ndi 3 × chiwerengero cha ma flywheel akumbuyo ndi 8, chomwe ndi 24, zomwe zikutanthauza kuti ndi 24-speed. Ngati flywheel yakumbuyo ili ndi zidutswa 10, momwemonso, galimoto yanu idzakhala 3×10=30, zomwe zikutanthauza kuti ndi 30 speed.
Mawilo a njinga zamapiri amaphatikizapo mawilo a 8 mpaka 24, 9 mpaka 27, ndi 10 mpaka 30. Ndipotu, okwera sagwiritsa ntchito magiya onse. Amagwiritsa ntchito giya imodzi yokha 80% ya nthawi. Giya iyi iyenera kukhala yoyenera kwambiri pa mphamvu ya wokwera komanso kuchuluka kwa mapedali ake.
Zikuoneka kuti magiya ambiri akakhala ndi makina otumizira magiya, dalaivala amatha kusankha bwino giya yomwe imamuyenerera. Magiya a 27-speed ali ndi magiya atatu ochulukirapo kuposa a 24-speed, zomwe zimapatsa dalaivala mwayi wosankha zambiri. Ndipo magiya ambiri akamakhalapo, kusintha kwake kumakhala kosavuta.
