Fork offset ni shyashya kurutonde rwibipimo byo gupima MTB, kandi umwanya wacyo ku mbonerahamwe izwi irahanagurwa nta mpaka nyinshi.Muri make, ni intera yapimwe hagati ya steer axe ya fork na axe y'imbere, ihindurwa hakoreshejwe offsets zitandukanye hejuru yikibanza.Ibicuruzwa byatangiye gushushanya geometrie yabo hamwe na offsets ngufi, kandi uyumunsi biragoye kubona igare 29 ″ rifite hejuru ya 44mm ya offset.Amazi yarahindutse.Ariko bigenda bite iyo dushyize 51mm ya offset kuri gare ya 44mm cyangwa 41mm?
Ubwa mbere, reka turebe vuba kuri offsets n'impamvu offset ngufi ishobora kuba ingirakamaro.Umwanditsi mukuru wacu Matt Miller yanditse ingingo ivuga kuri offset hashize igihe, bityo rero urebe neza ko ubigenzura.Muri make, ikibanza kigufi cya offset cyongera ubunini bwikirenge.Ibi bigerwaho hongerwa intera iri hagati yipine yubutaka hejuru yubutaka hamwe nu murongo uyobora inzira.Ingano nini yinzira itanga ihame ryinshi kandi ryiza ryimbere.Igitekerezo cyoroshye nuko uruziga rwimbere rworoshye kwikosora, gukurikira imirongo igororotse muburyo busanzwe aho kumva wobbly.Reba, mama, biroroshye gutwara igare ridafite amaboko!
Umuyoboro urekuye ufasha kugabanya ibyiyumvo byumutwe, kugenda bihamye bikunze gukundwa kuri ibyo bikinisho bimwe bikurura imbaraga, ubu rero dufite 29 ″ fork hamwe na 41-44mm ya offset, nini.Byinshi 27.5 ″ ibyuma bifite 37mm byurugendo.Gufata igihe gito kandi bigabanya igare ryikinga, bigatuma igare rinini ricungwa neza, kimwe no korohereza uyigenderaho gupima neza uruziga rwimbere kugirango rukururwe cyane.
Mperutse gutangira kugerageza 170mm Öhlins RXF38 m.2 banyoherereza offset ya 51mm.Privateer 161 na Raaw Madonna I ikizamini gisaba offset ya 44mm, ariko ibirango byombi bivuga ko 51mm izakora neza.Byakozwe?
Nahinduye amagare abiri hamwe na Öhlins 38 na Fox 38 kandi uburambe bwanjye bushobora kuvugwa muri make ngo "kugura ikibanza gishya ntacyo bitwaye".Nubwo ushobora kumva impinduka mugukemura, ni bito cyane kuburyo nibagiwe hagati yumanuka wambere igihe cyose mpinduye ahantu.Nzi neza ko ndamutse ngeze kuri gare yawe ngakora laps nkeya, sinshobora kumenya icyo fork offset aricyo ntareba.Njye mbona rwose numva gutandukana no guhindagurika kuri gare yanjye, kuba naragerageje ibice byinshi bitandukanye hamwe namakadiri, kandi kuriyi kadamu hamwe na fork ikomatanya, offset ntabwo isa nkibisobanura imikorere ihinduka.
Icyo numva nuko kuyobora hamwe nuburebure burebure bwa 51mm byoroheje gato kandi kuzunguruka kuruhande biroroshye kubigeraho kuruta hamwe na 44mm.Iyi dip ntabwo yari nini cyane kuburyo nari nkeneye kugera imbere yintebe cyangwa gufata imikandara ku butaka bubi.Ni itandukaniro rito, nka 0.5 ° umutwe wa tube inguni yibagirwa vuba.Ndabona ko abatwara ibinyabiziga bamwe bitabira neza kwikosora-kwikosora bumva kandi ibi bigomba kwitabwaho.
Ntakibazo nagize cyo kongera uburemere kumuziga w'imbere kuko aya magare yari maremare bihagije kuburyo nari ngomba guhindura ibiro byanjye imbere.Nta mpinduka zikomeye zihari.Na none, ukurikije ko nkunda amagare maremare, itandukaniro muburebure bwibiziga ntabwo bimbabaza.Inshuti yanjye, injeniyeri yigihe cyose yimodoka yo mumisozi, yagerageje ibyuma byombi kuri gare imwe maze yemera ko bombi bakora neza.Amaze kwiruka, ntashobora no kwibuka ikibanza yarimo atareba hasi.Kubwamahirwe, turi ibiremwa bihuza n'imiterere, kandi biroroshye guhuza nimpinduka nto.
Niba intego zanjye zitandukanye kandi buri kimwe cya cumi cyamasegonda cyagize ingaruka kumyuga yanjye yo kwiruka yabigize umwuga, nahitamo byanze bikunze forset ngufi.Kubakeneye gutekana kwinshi nibikorwa byibuze byunguka kugirango bagumane umushahara wabo, itandukaniro nkiryo, nibagiwe, birakwiye.Kubantu benshi bakunda umuhanda utari mumuhanda nkanjye, amahirwe nuko ikibanza usanzwe ufite kizakorana cyane na gare ugura, mugihe cyose ihuye na fagitire.
Mugenzi wanjye w'inararibonye Matt Miller yagize uburambe butandukanye cyane bwo gushiraho agafuni maremare kuri gare ya mugenzi we.Nifuzaga ko byamubera byiza, bityo twarangije kugurisha amahwa ashaje no kugura icyuma cyakoreshejwe imbere ya 37mm. ”
Mubyabaye kuri Mat, iki cyifuzo cya offset gisa nkaho gishingiye cyane kuri gare ivugwa nuwigenderaho.Niba usanzwe ufite forset ya offset idasabwa kuri gare yawe, nibyiza kubigerageza mbere yo gusiba ikotomoni yawe kubintu bishya.Urashobora no guhitamo kudahuza ubunini buteganijwe.
Reba ijambo "caster" urebe uburyo bigira ingaruka ku kuyobora no kuyobora.igira uruhare runini mu mikorere ya gare.Caster ni ihuriro rya HTA na Rake.
