Whakatikatikahia te derailleur o mua. E rua ngā tīwiri kei te derailleur o mua. Ko tētahi he tohu "H" me tētahi he tohu "L". Mena kāore te mowhiti mekameka nui i te whenua engari ko te mowhiti mekameka waenga i te whenua, ka taea e koe te whakatikatika i te L kia tata atu ai te derailleur o mua ki te mowhiti mekameka whakatikatika.
Ko te mahi a te pūnaha tuku pahikara he whakarerekē i te tere o te waka mā te whakarerekē i te mahi tahi i waenga i te mekameka me ngā pereti taputapu o ngā rahi rerekē o mua me muri. Ko te rahi o te mowhiti mekameka o mua me te rahi o te mowhiti mekameka o muri e whakatau ana i te kaha o te hurihanga o ngā pātara pahikara.
Ko te nui ake o te mowhiti mekameka o mua, ko te iti ake hoki o te mowhiti mekameka o muri, ko te nui ake o te mahi i te wā e pēhi ana. Ko te iti ake o te mowhiti mekameka o mua, ko te nui ake hoki o te mowhiti mekameka o muri, ko te māmā ake o te wā e pēhi ana. E ai ki ngā pūkenga o ngā kaieke rerekē, ka taea te whakarite i te tere o te pahikara mā te whakarite i te rahi o ngā mowhiti mekameka o mua me muri, mā te whakarite rānei i ngā wāhanga rori me ngā āhuatanga rori rerekē.
Ngā mōhiohio whānui:
Ina mutu te pēhi i te pēra, kāore te mekameka me te koti e hurihuri, engari ka akiaki tonu te wira o muri i te uho me te tīraka kia hurihuri whakamua i raro i te mahi a te inertia. I tēnei wā, ka paheke ngā niho o roto o te wira rere tetahi ki tetahi, ka pēhi i te uho ki te uho. I roto i te mokowā o te tamaiti, ka pēhi anō a Qianjin i te puna Qianjin. Ina paheke te pito o te niho tīraka ki te tihi o te niho o roto o te wira rere, ko te puna tīraka te mea tino pēhi. Ki te paheke whakamua pakupaku, ka pekehia te tīraka e te puna tīraka ki te pūtake niho, ka puta he tangi "pāwhiri".
Ka tere ake te hurihuri o te uho, ā, ka tere te paheke o te taumaha ki runga i ngā niho o roto o ia wira rere, ka puta he tangi "pāwhiri-pāwhiri". Ina takahia te pētera ki te taha ke, ka huri te koti ki te taha ke, ka tere ake te paheke o te hū, ka tere ake te tangi "pāwhiri-pāwhiri". He wāhanga nui te wira rere maha-wāhanga i roto i te tuku pahikara.
