I ētahi wā, ko ngā otinga pai rawa atu ko ngā mea māmā rawa.

Kua amuamu tātou katoa, i te mea ka auaha te hangarau i runga i te pahikara, ka uaua ake te pahikara, ka piki ake hoki te utu o te pupuri. Engari ehara i te mea koinā anake, kei reira ētahi whakaaro pai hei whakangawari ake i te pahikara, hei whakapai ake hoki.

Kaua e whakamahi i ngā pūnaha whakatārewatanga uaua, e tāpiri rānei i ngā hikohiko ki te motuka, ko te hoahoa pai rawa atu ko te pātai ki a koe anō, he mea nui ēnei? Ko te tikanga whānui, ko te māmā ake te hanga i tō motuka kia māmā ake, kia marino ake, kia iti ake te utu, kia māmā ake te tiaki me te pono ake. Ehara i te mea koinā anake, engari mā te kaupapa whānui māmā ake ka ātaahua ake, ka matatau ake hoki te āhua o tō motuka.

Anei ētahi tauira, ko te iti he nui.

1. Pūwāhi tahuri ngāwari

I ēnei rā, tata ki ngā pahikara XC katoa ka hangaia he "pivot flex" hei utu mō te pivot tuku iho me ngā peera. He take anō hoki tēnei, he māmā ake ngā pivot rapa, he maha ngā wāhanga iti ka whakaitihia (ngā peera, ngā pūtu, ngā horoi…) ā, ka māmā ake te tiaki i te pūnaha katoa.

Ahakoa kotahi noa te wā e hiahiatia ana kia whakakapia ngā peera, he mea hanga ngā porowhita piko kia roa ai te ora o te anga. Ko ngā pūwāhi porowhita kei muri o te anga, ahakoa kei runga i ngā nohoanga, i ngā mekameka rānei, ka kitea i a rātou e hurihuri ana i ngā wā maha i te nekehanga whakatārewatanga.

Ko te tikanga o tēnei, tera pea ka tere ake te pakaru o te peera, ka nui ake hoki ngā mate nā te mea kei te pā tonu te kaha ki te pūwāhi kotahi. Ka taea e ngā anga ngāwari i hangaia ki te waro, te maitai, te konumohe rānei te whakauru i tēnei whānuitanga nekehanga iti me te kore e ngenge. Inaianei, e kitea nuitia ana ēnei i runga i ngā pahikara he 120mm te tawhiti haere, iti iho rānei.

2. He pai te pūnaha kōpae kotahi mō te katoa

Mō te kaieke maunga tino matatau, tera pea ka tino kitea ngā painga o te pūnaha mowhiti mekameka kotahi, ā, tata kore e kōrerohia. Mā ēnei ka taea e tātou te whakakore i ngā derailleurs o mua, ngā derailleurs o mua, ngā taura me ngā arataki mekameka (he maha ngā wā kua whakauruhia), me te tuku tonu i ngā momo ōwehenga taputapu. Engari mō ngā kaieke tauhou, ko ngā āhuatanga ngāwari me te ngāwari ki te whakahaere o te pūnaha kōpae kotahi he pai ake mō te eke. Ehara i te mea he māmā ake te tāuta me te tiaki noa iho, engari ka māmā ake hoki te eke nā te mea me manukanuka noa koe ki te kotahi te neke me te rīpene matotoru tonu.

Ahakoa ehara i te mea hou rawa atu ēnei hangarau, ka taea e koe te hoko i ngā pahikara maunga taumata-whakamutunga me ngā pūnaha taraiwa kotahi-porowhita pai. He mea tino pai tēnei mō te tangata e tīmata ana ki te hākinakina.

3. Pūnaha whakatārewatanga porowhita kotahi

Ko te take matua mō te whakamahi i te hoahoa Horst-link (koinei te hoahoa tino noa i ēnei rā) ki te wāhanga kotahi-pivot o te hononga whakatārewatanga, he whakaiti me te whakatika i te pānga o ngā kaha aukati ki ngā āhuatanga ārai-piki o te whakatārewatanga. E kīia ana mā tēnei ka ngāwari ake te whakamahi a te whakatārewatanga i te whakatārewatanga i te wā e aukati ana. Engari, ehara i te mea nui. Inaa, ko te ātete teitei ki te piki o ngā pivot kotahi ka āwhina i a rātou ki te ārai i ngā pānga o te kaha aukati, ā, ka pai ake te pumau i raro i te aukati, he pānga tino kitea tēnei ki taku whakaaro.

4. He whiu nui ake

He maha ngā huarahi hei whakapai ake i te mahi whakatārewatanga: ngā hononga whakahirahira, ngā ru utu nui, ngā idlers. Engari kotahi anake te huarahi tino tika hei āwhina i te pahikara ki te whakangawari i ngā puku: kia nui ake te haere o te whakatārewatanga.

Ahakoa kāore te tāpiri i te nekeneke nui e whakapiki ake i te taumaha, te utu, te uaua rānei o te pūnaha whānui, ka tino rerekē te pai o te mimiti o te pahikara i ngā ru. Ahakoa kāore te katoa e hiahia ana ki te ekenga papatahi, ka taea e koe te hanga i te pahikara haere-roa kia pakari mā te whakaiti i te totohu, te raka i te whakatārewatanga, te tāpiri rānei i ngā āputa oro. Engari kāore e taea e koe te hanga i te ekenga pahikara haere-poto kia ngohengohe e hiahia ana koe, ki te kore ka heke te whakatārewatanga ki raro.

5. Kōpae Nui

Ka whakapai ake ngā rotor nunui i te pai o te aukati, te tohatoha wera me te ōritetanga, me te kore e tāpiri i te uaua. Ki te whakatauritea ki ngā kōpae 200mm, ka taea e ngā kōpae 220mm te whakapai ake i te pai o te aukati mā te 10% pea, me te whakarato hoki i te mata nui ake hei tohatoha wera.
