Imininingwane yamaketanga okugoqa anemigqa emibili ifaka phakathi imodeli yeketanga, inani lezixhumanisi, inani lama-rollers, njll.
1. Imodeli yeketanga: Imodeli yeketanga eligoqekayo elinemigqa emibili ivame ukuba nezinombolo nezinhlamvu, njengo-40-2, 50-2, njll. Phakathi kwazo, inombolo imele isisekelo samasondo seketanga, iyunithi ingu-1/8 intshi; uhlamvu lumelela isimo sesakhiwo seketanga, njengo-A, B, C, njll. Izinhlobo ezahlukene zeketanga zifanele imishini ehlukene yemishini futhi zidinga ukukhethwa ngokwesimo sangempela.
2. Inani lezixhumanisi: Inani lezixhumanisi zeketanga eligoqayo elinemigqa emibili ngokuvamile liyinombolo elinganayo. Isibonelo, inani lezixhumanisi zeketanga elingu-40-2 lingu-80. Inani lezixhumanisi lithinta ngqo ubude kanye nomthamo wokuthwala umthwalo weketanga, futhi kudingeka likhethwe ngokwezidingo zangempela.
3. Inani lama-roller: Ububanzi besixhumanisi se-roller chain enemigqa emibili ngokuvamile buyi-1/2 intshi noma ama-intshi angu-5/8. Ububanzi obuhlukene bezixhumanisi bufanele imishini ehlukene yemishini. Ubukhulu bobubanzi besixhumanisi buzothinta nomthamo wokuthwala umthwalo we-chain. Umthamo kanye nesikhathi sesevisi.
