E rua ngā tīwiri kei te pūwhakawhiti o mua, kua tohua ki te "H" me te "L" i te taha, e whakawhāiti ana i te whānuitanga o te nekehanga o te pūwhakawhiti. I roto i ēnei, ko te "H" e pā ana ki te tere tere, arā, te taupoki nui, ā, ko te "L" e pā ana ki te tere iti, arā, te taupoki iti.
Ki te pito o te mekameka e hiahia ana koe ki te huri i te derailleur, hurihia noa te tīwiri o taua taha ki waho. Kaua e whakau kia kore ra ano he waku, ki te kore ka taka te mekameka; me noho tonu te nekehanga. Mena kei te mowhiti o waho te mekameka wira o mua, ā, kei te mowhiti o roto te mekameka wira o muri, he mea noa te puta o te waku.
Ko te nuinga o te wā ka whakaritea te tīwiri HL kia rite ki te āhua o te nekehanga. I te wā e whakarite ana i te raruraru waku, kia tino mohio kei te mirimiri tonu te mekameka ki te taha kotahi o ngā taputapu o mua me muri i mua i te whakarite.
Ngā whakatūpato mō te whakamahi i ngā pahikara maunga:
Me horoi tonu ngā pahikara kia mau tonu te ma. Hei horoi i te pahikara, whakamahia he ranunga o te 50% hinu miihini me te 50% penehīni hei horoi. Mā te horoi noa i te motuka ka kitea ngā hapa i roto i ngā wāhanga maha i te wā tika, ā, ka whakatika wawe tonu kia pai ai te haere o te whakangungu me te whakataetae.
Me horoi e ngā kaitākaro ā rātou waka i ia rā, i ia rā. Mā te horoi, ehara i te mea ka noho ma, ka ataahua hoki te pahikara, engari ka āwhina hoki ki te tirotiro i te kounga o ngā wāhanga rerekē o te pahikara, me te whakatipu i te māramatanga o te kawenga me te ngaio o ngā kaitākaro.
I te tirotiro i te waka, kia tūpato ki ngā mea nei: kaua he kapiti, he rerekētanga rānei i roto i te anga, te marau o mua me ētahi atu wāhanga, me piri ngā tīwiri o ia wāhanga, ā, me ngāwari te huri o ngā kakau.
Tirohia marietia ia hononga o te mekameka hei tango i ngā hononga pakaru, me te whakakapi i ngā hononga mate kia pai ai te mahi a te mekameka. Kaua e whakakapia te mekameka ki tētahi mea hou i te wā whakataetae, kia kore ai e ōrite te mekameka hou ki te taputapu tawhito, ā, ka taka te mekameka. Mēnā me whakakapi, me whakakapi ngātahi te mekameka me te wira rere.
