Ezivamile zifaka phakathi isakhiwo sezingxenye eyodwa, isakhiwo sezingcezu ezi-5 noma ezi-6 (izimoto zokudlulisa zakuqala), isakhiwo sezingcezu ezi-7, isakhiwo sezingcezu ezi-8, isakhiwo sezingcezu ezi-9, isakhiwo sezingcezu ezi-10, isakhiwo sezingcezu ezi-11 kanye nesakhiwo sezingcezu ezi-12 (izimoto zomgwaqo).
Ijubane elingu-8, 9, kanye no-10 limelela inani lamagiya kusondo eliyindilinga elingemuva. Uma ijubane liphakeme, uchungechunge luyancipha. Ngoba wonke ama-pedal amabhayisikili asezintabeni anama-chainring amathathu, uma isondo lakho eliyindilinga elingemuva linama-8, lokho kusho ukuthi inani lama-chainring lingu-3 × inani lama-flywheel angemuva lingu-8, okulingana no-24, okusho ukuthi liyi-speed engu-24. Uma isondo eliyindilinga elingemuva linezingcezu ezingu-10, ngendlela efanayo, imoto yakho izoba ngu-3×10=30, okusho ukuthi ijubane elingu-30.
Amasondo okuhamba ngamabhayisikili asezintabeni ahlanganisa amasondo okuhamba ngamabhayisikili asuka ku-8 kuya ku-24, 9 kuya ku-27, kanye ne-10 kuya ku-30. Eqinisweni, abagibeli ngeke basebenzise wonke amagiya. Basebenzisa igiya elilodwa kuphela isikhathi esingama-80%. Leli giya kumele libe elifanele kakhulu amandla kanye nemvamisa yokupheda komgibeli.
Kuyabonakala ukuthi uma uhlelo lokudlulisa lunamagiya amaningi, kulapho umshayeli engakhetha khona igiya elimfanele ngokunembe kakhudlwana. Ijubane elingama-27 linamagiya amathathu engeziwe kunejubane elingama-24, okunikeza umshayeli izinketho eziningi. Futhi uma amagiya eningi, kulapho ukushintshashintsha kushelela khona.
