Ni uruhe runigi rw'amagare rufite umubare w'ibizingo

Iminyururu y'amagare ni kimwe mu bintu by'ingenzi bigize umuhanda w'amagare. Ishinzwe kohereza ingufu kuva kuri pedali kugera ku ruziga rw'inyuma, bigatuma igare rikomeza kugenda. Ariko se wigeze wibaza umubare w'iminyururu ikoreshwa cyane ku minyururu y'amagare?

Mu isi y'amagare, iminyururu y'imizingo ishyirwa mu byiciro hakurikijwe ubunini, ari na yo ntera iri hagati y'iminyururu y'imizingo ikurikirana. Gupima ubunini bw'imizingo bigira uruhare runini mu kugena uburyo umunyururu uhura n'iminyururu y'amagare n'iminyururu.

Umunyururu usanzwe ukoreshwa cyane ku magare ni umunyururu wa santimetero 1.5. Ibi bivuze ko intera iri hagati y’aho hagati y’udupira tubiri dukurikirana ari igice cya santimetero. Iminyururu ya santimetero 1.5 ikoreshwa cyane mu nganda z’amagare bitewe n’uko ihura n’ibice bitandukanye by’imodoka ndetse no koroshya kuyikoresha.

Ariko, ni ngombwa kumenya ko iminyururu y'amagare iza mu bugari butandukanye, ibyo bikaba bishobora kugira ingaruka ku buryo ihura n'ibikoresho bitandukanye. Ubugari busanzwe ku minyururu y'amagare ni santimetero 1/8 na santimetero 3/32. Iminyururu ya santimetero 1/8 ikoreshwa ku magare afite umuvuduko umwe cyangwa amwe mu magare afite ibikoresho bihamye, mu gihe iminyururu ya santimetero 3/32 ikoreshwa ku magare afite umuvuduko mwinshi.

Ubugari bw'umunyururu bugenwa n'ubugari bw'udupira n'amasano. Amagare yihuta rimwe akunze gukoresha iminyururu minini kugira ngo arambe kandi agire ubusugire. Ku rundi ruhande, amagare yihuta menshi akoresha iminyururu mito kugira ngo ahuze neza hagati y'iminyururu iri hagati y'iminyururu.

Byongeye kandi, umubare wa vitesi mu gice cyo gukurura igare ryawe ushobora kugira ingaruka ku bwoko bw'umunyururu ukoreshwa. Vitesi imwe yo gukurura igare ikoresha umunyururu wa santimetero 1/8 z'ubugari. Ariko, amagare afite vitesi za derailleur asaba iminyururu mito kugira ngo ijyane neza n'impinduka hagati ya vitesi. Iyi minyururu akenshi iba ifite imiterere igoye kandi ishobora gushyirwaho imibare nka 6, 7, 8, 9, 10, 11 cyangwa 12 kugira ngo yerekane ko ihuye n'igice cyo gukurura igare runaka.

Kugira ngo umugozi w'igare ryawe urusheho gukora neza kandi urambe, ni ngombwa guhitamo umugozi ukwiye igare ryawe. Gukoresha umugozi utemewe bishobora gutuma uhindagurika nabi, kwangirika cyane ndetse no kwangirika kw'ibice by'umuyoboro w'igare bishobora kwangiza.

Kubwibyo, ni byiza kureba amabwiriza y’uruganda cyangwa gusaba inama z’umukanishi w’igare w’inzobere mu guhitamo umugozi wo gusimbuza igare ryawe. Bashobora kugufasha kumenya ubugari bukwiye bw’umugozi n’umuvuduko bihuye n’uburyo igare ryawe ritwara.

Muri make, ubwoko busanzwe bw'umunyururu w'amagare ni umunyururu w'igare wa santimetero 1.5. Ariko, ubugari bw'umunyururu n'uburyo uhuza n'ibikoresho by'amagare bigomba kwitabwaho. Guhitamo umunyururu ukwiye bituma ingufu zikwirakwira neza kandi neza, bigatuma habaho uburambe bwiza bwo kugenda.
