Nui aʻe kā mākou kaulahao ma nā kaʻa kaʻa ma mua o ka hoʻolako maʻamau.Ua hiki iā lākou ke neʻe mālie ma waena o nā kaʻa, me ka haʻihaʻi ʻole i kā mākou mele, ʻoiai lākou i lawe mai i ka mana piha o kā mākou mau sprint ikaika loa.Eia naʻe, hiki mai kēia ʻano paradoxical ma ke kumu kūʻai: I ka wā lōʻihi, pau nā pine o ke kaulahao a me nā loulou i loko, e piʻi ai ka mamao ma waena o kēlā me kēia loulou.'Ōlelo pinepine 'ia kēia ma ke 'ano he "chain stretching", 'oiai 'a'ole hiki ke ho'opa'a 'ia ka metala.Ina ke kaulahao (kapalaki hoʻomaʻemaʻe kaulahao kaʻano laila） ʻaʻole i hoʻololi ʻia, hiki ke hoʻopilikia ʻia ka hoʻololi ʻana a hiki i ka pilikia ke haki ke kaulahao.
ʻO ka mea pōmaikaʻi, ʻaʻole ia he kumukūʻai ke hoʻololi i ke kaulahao paʻa, ʻoi aku inā ʻoe e hana iā ʻoe iho.ʻO ka mea ʻē aʻe, ʻoi aku ka maʻalahi o ka ʻimi ʻana i nā ʻāpana kūpono inā ʻike ʻoe i nā mea i loaʻa iā ʻoe.Eia nō naʻe, he nui nā pitfalls i ka hoʻolilo nui ʻana i nā loaʻa marginal, a hiki i kekahi manawa ke paʻakikī ke hoʻoholo i ka wā e pono ai ke kumukūʻai o ka huakaʻi a i ʻole ka mālama kaumaha.Inā makemake ʻoe e ʻano hou kāu kaʻa i kēlā me kēia manawa āu e hoʻohuli ai i ke kīkī me ka ʻole o ka haki ʻana i ka panakō, ua uhi wau iā ʻoe.
ʻO ka cassette, a i ʻole ka helu o nā sprockets ma luna o ia, ʻo ia paha ka mea nui loa i ke koho ʻana i ke kaulahao kaʻa.ʻOi aku i loko o nā hui pūʻulu hou aku, ʻo ka derailleur hope holoʻokoʻa, me ka derailleur, cassette/chocks, a me ke kaulahao, pono e holo mālie.ʻO ke kiʻekiʻe o ka wikiwiki o ka hoʻouna ʻana, ʻoi aku ka lahilahi o ke kaulahao;ʻoiai he hapa o ka millimeter ka ʻokoʻa, he hoʻololi hoʻohālikelike ia i ka laulā o nā niho a me nā āpau ma waena o lākou.ʻO ke kaulahao me ka helu hewa ʻole o ka wikiwiki e neʻe nui loa, e kuʻi i nā cogs pili, a ʻaʻole kūpono paha.ʻAʻole maʻamau kēia pilikia me 8 mau wikiwiki a i ʻole ka haʻahaʻa, no ka mea, ʻo kēlā mau kaulahao ua like ka laulā, akā maikaʻi ke ʻike e pili ana i kēlā me kēia kaʻa me ka nui o nā sprockets.
I loko o nā pūʻulu hui hou (ʻoi aku ka wikiwiki o 11 a me 12), hoʻolālā nā brand i nā mea hana a me nā kaulahao e maʻalahi ai ka hoʻololi ʻana, a hana ʻokoʻa lākou.Hiki i kēia ke alakaʻi i ka neʻe ʻana a me ka lele ʻana i ka drivetrain hewa, no laila e hoʻāʻo e hui like me kēia - Shimano iā Shimano, SRAM i SRAM a me Campagnolo i Campagnolo.Eia kekahi, ʻo nā loulou nui, a me nā puʻupuʻu e komo ai nā kaulahao, e hilinaʻi pinepine ʻia i ka wikiwiki a me ka brand, a ʻaʻole kūpono paha ka nui hewa ʻole i ka wā e holo ana - ʻaʻole kūpono.
He mau nīnau hou aʻe, e ʻoluʻolu e kūkākūkā!ʻO kā mākou hale hana he ʻoihana piha i ka hana ʻana onā mea hana mālama kaʻa, kamepiula paikikala, pū a me nā kukui kaʻa.
