Njinga zathu zimakhala ndi maunyolo ochulukirapo modabwitsa poyerekeza ndi zomwe zimaperekedwa.Bazyali balakonzya kucinca magiya munzila iitali kabotu, kubikkilizya akunyonganya njiisyo yesu mbobakonzya kubelekela antoomwe amakanze aakwe.Komabe, pali mtengo wokhudzana ndi kukhala ndi chikhalidwe chodabwitsa chotere: Pamene nthawi ikupita, zikhomo ndi zolumikizira zamkati za unyolo zimawonongeka, zomwe zimapangitsa kuti mtunda uwonjezeke womwe umalekanitsa ulalo uliwonse.Ngakhale kuti chitsulo sichimatambasula mwanjira iliyonse yomwe ingayesedwe, chodabwitsachi chimatchedwa "kutambasula kwa unyolo."Ngati unyolo sunasinthidwe, kusuntha kungakhudzidwe moyipa, ndipo pakhoza kukhala zovuta ngati unyolo uduka.Thebicycle chain kuyeretsa burashiamagwiritsidwa ntchito kuyeretsa unyolo.
Kuti munthu apeze mpumulo, mtengo wosinthira tcheni chanjinga umakhala wotsika kwambiri, makamaka ngati ntchitoyo waichita yekha.Kuphatikiza pa izi, ngati mukudziwa zigawo zomwe muli nazo kale, kupeza zigawo zoyenera sikuyenera kukhala kovuta kwambiri.Komabe, pali misampha yambiri yokhudzana ndi kugulitsa ndalama mopitilira muyeso, ndipo zingakhale zovuta kudziwa ngati ulendo wowonjezera kapena kupulumutsa kulemera kuli koyenera kulipira.Nthawi zina zimakhala zovuta kudziwa nthawi yomwe kuyenda kowonjezera kapena kupulumutsa kulemera kuli koyenera kulipira.Ngati mukufuna kuti njinga yanu iwoneke yatsopano nthawi zonse mukatembenuza phokoso, koma simukufuna kugwiritsa ntchito mkono ndi mwendo, ndili ndi yankho lanu.
Posankha unyolo wa njinga, kaseti, yomwe imadziwikanso kuti kuchuluka kwa ma sprockets pa iyo, ndiyomwe ndiyofunikira kwambiri kuiganizira.Kuonetsetsa kuti zonse zili m'manjachotsegulira njinga, kuphatikizapo unyolo, makaseti / chocks, ndi derailleur, zimayenda bwino, mulingo wodabwitsa wolondola umafunika, makamaka m'magulu amasiku ano.Liwiro la kufala likawonjezedwa, unyolo nawonso umakhala wocheperako.Ngakhale kuti kusiyanako kungakhale kokha mazana angapo a millimeters, izi zikuimira kusintha kwakukulu poyerekeza ndi m'lifupi mwa mano ndi mtunda wapakati pawo.Ngati unyolo uli ndi kuchuluka kolakwika kwa liwiro, kuyenda kwake kumakhala koyipa kwambiri, ndipo kumatha kupangitsa kuti ma cogs oyandikana nawo awonongeke.Chifukwa maunyolo panjinga zothamanga zisanu ndi zitatu kapena zocheperapo ndi ofanana m'lifupi, izi sizovuta;komabe, ndikofunikira kudziwa zambiri zokhudza njinga iliyonse yomwe ili ndi ma sprockets ambiri.
Mtundu uliwonse wamagulu amakono (makamaka omwe ali ndi liwiro la 11 ndi 12) amapanga magiya ake ndi maunyolo kuti azisuntha mosavuta, koma aliyense amazichita mwanjira yakeyake.Izi nthawi zina zimatha kupangitsa kusuntha kovutirapo ndikudumphira mumayendedwe olakwika, ndiye yesani kulumikiza motere: Shimano kupita ku Shimano, SRAM kupita ku SRAM, ndi Campagnolo kupita ku Campagnolo.Shimano kupita ku SRAM nthawi zina kungayambitse kusuntha kosasunthika ndikudumpha mu drivetrain yolakwika.Kuphatikiza apo, maulalo akulu komanso zomangira zomwe maunyolo amalowera nthawi zambiri zimadalira liwiro ndi mtundu.Ngati kukula kolakwika kukugwiritsidwa ntchito, maunyolowo sangakwane konse kapena amatha kunjenjemera mukukwera, zomwe sizili bwino.
Khalani ndi mafunso ochulukirapo, mwalandiridwa kuti mukambirane!Malo athu opangira zinthu ndi bizinezi yophatikiza zonse yomwe imagwira ntchito yopanga nyanga zamagalimoto, magetsi apagalimoto, makompyuta apanjinga, ndizida zokonzera njinga.
