Niba udafite umukandara cyangwa utwaye igiceri kimwe, ntuzagera kure cyane udafite urunigi kuri gare yawe.Ntabwo ari ibintu bishimishije cyane, ariko urabikeneye niba ushaka kujya ahantu hose.
Hariho ikoranabuhanga ryinshi rijya gukora urunigi rwamagare, nubwo imikorere yarwo igororotse.Iri koranabuhanga ryemeza ko urunigi ruzahuza neza nu munyururu uri kuri crankset hamwe na cassette spockets inyuma, bigatuma ihinduka neza igihe cyose bibaye ngombwa.
Hano haribintu byose byerekeranye numunyururu wamagare ugomba kumenya, harimo imiterere yumunyururu, ubwoko butandukanye bwurunigi "umuvuduko", guhuza, uburebure bwurunigi, nibindi byinshi.
Ni ubuhe buryo bw'urunigi rw'amagare?
Urunigi rushobora gucikamo ibice kugiti cye kizwi nkumuhuza.Ihuza mubice byinshi byurunigi bisimburana hagati yubugari kandi bugufi, kandi ubu buryo busubirwamo murwego rwose.
Uruziga rushyizwe ku rutugu rw'umuhuza wo hanze, kandi buri murongo uhuza ibyapa bibiri bifatanye hamwe na rivets, rimwe na rimwe byitwa pin.Birashoboka ko habaho ibihuru bitandukanye kuruhande rwuruziga muminyururu imwe;icyakora, iminyururu igezweho ntabwo isanzwe ifite iyi.
Kugirango urunigi rukomeze, guhuza pin (rimwe na rimwe bita 'rivet') birashobora gusunikwa igice-kiva kumurongo ukoresheje aigikoresho cy'amagarehanyuma usubize inyuma mumurongo uzengurutse umurongo uva kurundi ruhande.
Bimwe byihuta-byihuta birashobora gutandukana kandi birashobora gukoreshwa, mugihe ibindi, nkibikoreshwa mumurongo wa Shimano na SRAM murwego rwo hejuru, ntibishobora gutandukana bimaze gushyirwaho, kuko guhuza byihuse ntabwo bikomeye cyane icya kabiri umwanya wose.
Ariko, abatwara ibinyabiziga hamwe nabakanishi bongera gukoresha-byihuse nta kibazo.Ni wowe bireba niba ushaka gufata ibyago.
Ni ryari nshobora gusimbuza urunigi?
Gukoresha aigarenuburyo bwiza cyane bwo kumenya igihe nikigera cyo gusimbuza urunigi.Mugihe ukeneye cyane cyane guhindura urunigi rwawe bizagenwa nigihe, uburyo, n'aho utwara igare ryawe.
Iyo ingoyi zimaze kwambarwa, zirarambura, kandi ubwinshi bwimigendere ishobora kugaragara hagati yihuza nayo iriyongera.Igikorwa cyo kunyeganyega gishobora kuvamo guhindagurika, mugihe kurambura bishobora gushira vuba kaseti kandi, buhoro buhoro, iminyururu.Ibi bibazo byombi birashobora guterwa no kugenda kuruhande.
Kuberako ari ngari gato, iminyururu ifite umuvuduko icumi cyangwa munsi yayo irashobora guhindura ikibanza cyayo kuri 0,75 kuri cheque yiminyururu mbere yuko ikenera gusimburwa.
Uzakenera kandi gusimbuza cassette yawe niba kurambura kumurongo wihuta wa 11-13 bigeze kuri 0,75, cyangwa niba kurambura kumurongo wawe wihuta 6-10 bigeze 1.0.Iyo ibizunguruka ku munyururu byambarwa, ntibiba bigihuye neza n'amenyo kuri cassette, bigatuma amenyo yangirika cyane.Birashoboka ko uzakenera no gusimbuza urunigi niba urunigi rwarashaje.
Bizagutwara amafaranga make yo gusimbuza urunigi gusa kuruta uko ruzasimbuza urunigi, iminyururu, na cassette aribyo bintu bitatu byingenzi bigize moteri yawe.Niba usimbuye urunigi rwawe mugihe rutangiye kwerekana ibimenyetso byambaye, birashoboka ko uzashobora gukora cassette yawe nu munyururu bimara igihe kinini.
Nkibisanzwe muri rusange, urashobora gukoresha iminyururu itatu kuri cassette imwe mugihe ukurikirana imyenda yumunyururu mugihe gikwiye.
Nigute nshobora gusimbuza urunigi?
Mugihe ukeneye gusimbuza urunigi, uzakenera agufungura amagareibyo birahujwe nuwakoze urunigi kugirango akureho urunigi rwawe rushaje hanyuma asunike urunigi.
Umaze guhanagura neza ibintu byose, uzakenera guhuza urunigi rwawe rushya unyuze mumashanyarazi, arimo ibiziga byumukino kuri derailleur yinyuma.
Uzakenera gukoresha urunigi kugirango ukureho umubare ukwiye wihuza kugirango ubone urunigi rwawe muburebure bukwiye.Nyuma yibyo, uzakenera guhuza impera zombi zumunyururu hamwe.Kubindi bisobanuro, reba ingingo yacu yuburyo bwo gusimbuza urunigi rwamagare.
