Ngaphezu kwezinkinga zesondlo nokumiswa, siphinde sathola inqwaba yemibuzo ekhanda ikhanda mayelana nejometri yohlaka lwebhayisikili lezintaba.Umuntu uyazibuza ukuthi ukulinganisa ngakunye kubaluleke kangakanani, ukuthi zithinta kanjani izici zokugibela, nokuthi zisebenzisana kanjani nezinye izakhi zejiyomethri yebhayisikili nokumiswa. isakhiwo.Sizobheka kalukhuni ezinye zezilinganiso zejiyomethri ezibaluleke kakhulu ukuze sinciphise abagibeli abasha—siqale kubakaki abaphansi. Cishe akunakwenzeka ukumboza zonke izici zokuthi ukukala kohlaka olulodwa kuthinta kanjani indlela ibhayisikili eligibela ngayo, ngakho-ke senze konke okusemandleni ethu ukuze sifinyelele amaphuzu abalulekile athinta amabhayisikili amaningi.
Ubude bobakaki obungezansi isilinganiso esiqondile ukusuka phansi ukuya enkabeni ye-BB yebhayisikili lapho ukumiswa kunwetshwa ngokugcwele.Esinye isilinganiso, ukwehla kwe-BB, isilinganiso esiqondile esivela kumugqa ovundlile phakathi nendawo yehabhu yebhayisikili ukuya emugqeni ofanayo isikhungo se-BB.Lezi zilinganiso ezimbili zibalulekile ngezindlela ezahlukene uma ubheka ibhayisikili futhi unquma ukuthi lihamba kanjani.
Ukwehla kwe-BB kuvame ukusetshenziswa abagibeli ukuze babone ukuthi bangase bazizwe kanjani “ngaphakathi” futhi “basebenzise” ibhayisikili. Ukwehla kwe-BB okwengeziwe ngokuvamile kubangela umgibeli ogxilile futhi oqinisekayo ozizwa sengathi uhlezi ohlakeni kunokuba alugibele. I-BB ecwila phakathi kwama-ekseli ngokuvamile izizwa ingcono kune-BB ende lapho ushayela ngokuphenduka kanye nokungcola okungcolile. Lesi silinganiso ngokuvamile siyalungiswa futhi asithintwa amasayizi ahlukene esondo noma amasondo. Nokho, ama-flip chips ngokuvamile ashintsha enye yezinguquko zejometri. amafreyimu ane-flip chip angaphakamisa noma ehlise i-BB yawo ngo-5-6mm, ehlanganiswe namanye ama-engeli kanye nezilinganiso zethonya le-chip. Kuye ngomzila wakho kanye nezintandokazi zakho, lokhu kungashintsha ibhayisikili ukuze isilungiselelo esisodwa sisebenzele isikhungo esithile somzila, kuyilapho enye ifaneleka kangcono indawo ehlukile.
Ukuphakama kwe-BB ukusuka phansi ehlathini kuyahlukahluka kakhulu, ne-flip chip ihamba phezulu naphansi, izinguquko zobubanzi besondo, izinguquko zobude befoloko ukuya kumqhele, ukuhlangana kwamasondo, nanoma yikuphi okunye ukunyakaza kokukodwa noma kokubili kwalokhu. .Isici ebudlelwaneni be-asi yakho ne-dirt.BB ukuphakama okuncamelayo kuvame ukuba okomuntu siqu, abanye abagibeli bancamela ukuklwebha amaphedali emadwaleni egameni lokuzwakala okutshaliwe, kuyilapho abanye bekhetha ukudluliselwa okuphezulu, ngokuphepha ngaphandle kwengozi.
Izinto ezincane zingashintsha ubude be-BB, zenze izinguquko ezinengqondo endleleni ibhayisikili eliphatha ngayo.Isibonelo, imfoloko engu-170mm x 29in Fox 38 inesilinganiso somqhele esingu-583.7mm, kuyilapho ubukhulu obufanayo bulinganisa u-586mm ubude.Zonke ezinye izimfoloko emakethe osayizi abahlukene futhi izonikeza ibhayisikili ukunambitheka okuhlukile kancane.
Nganoma yiliphi ibhayisikili le-gravity, ukuma kwezinyawo nezandla zakho kubaluleke kakhulu ngoba ukuphela kwendawo othintana kuyo lapho wehla.Uma uqhathanisa ukuphakama kwe-BB nokwehla kwamafreyimu amabili ahlukene, kungasiza ukubona ukuphakama kwesitaki ngokuhlobene lezi zinombolo.Isitaki isilinganiso esiqondile phakathi komugqa owodwa ovundlile ku-BB nomunye umugqa ovundlile phakathi nendawo yokuvuleka kweshubhu lekhanda eliphezulu. Nakuba isitaki singalungiswa kusetshenziswa izikhala ezingenhla nangaphansi kwesiqu, kuwumqondo omuhle ukubheka. le nombolo ngaphambi kokuthenga ifreyimu ukuze uqiniseke ukuthi ungafinyelela ukuphakama kwesibambo oyifunayo, uma kuqhathaniswa ne-BB drop Effective ifaneleka kakhulu izidingo zakho.
Izingalo ezimfishane ze-crank kanye nonogada be-bash bakha isikhala esengeziwe nokuphepha kwe-BB ephansi, kodwa udinga ukubheka izinzwane zakho lapho ugibela amadwala amade. isibonelo, enkulu engiyigibelayo njengamanje inokwehla okungu-35mm BB okwenza ibhayisikili lizizwe lilihle ngesivinini esinesivinini esincane.Nge-crank engu-165mm efakiwe, angikwazanga ukuthola i-dropper post engu-170mm endaweni yokuhlala yohlaka engu-445mm ubude. cishe u-4mm phakathi kwekhola yesihlalo kanye nephansi kwekholola ye-dropper ukuze kube ne-BB ephansi, okuholela eshubhu lesihlalo eside noma izingalo ezinde zokudonsa kuzongiphoqa ukuthi nginciphise ukuhamba kwami ​​kwe-dropper noma ukugibela Uhlaka olunosayizi omncane;akukho kwaleyo ezwakalayo ekhangayo.Ngakolunye uhlangothi, abagibeli abade bazothola ukufakwa okwengeziwe kwesihlalo sokubonga ngenxa yokwehla kwe-BB eyengeziwe kanye neshubhu yokuhlala eyengeziwe, okunikeza iziqu zabo amandla okuthenga engeziwe ngaphakathi kohlaka.
Usayizi wesondo uyindlela elula yokulungisa ubude be-BB futhi wenze izinguquko ezinhle ku-angle yeshubhu lekhanda lebhayisikili ngaphandle kokuhlinzwa okukhulu.Uma ibhayisikili lakho lifika nesethi yamasondo angu-2.4-intshi futhi ufaka ingemuva elingu-2.35 intshi kanye nengaphambili elingu-2.6 intshi. izimfoloko, amaphedali ngaphansi ngokungangabazeki azozizwa ehlukile.Qaphela ukuthi ishadi lakho lejiyomethri yebhayisikili likalwa ngesondo eliyisipele engqondweni, ngakho ungazama izinhlanganisela ezihlukene ukuze uthuthukise ulwazi lwakho lokugibela.
Lezi ngezinye zezinto eziningi ezinomthelela ekuphakameni kwe-BB futhi zingathinta ukuphakama kwe-BB.Ingabe ukhona omunye ongabelana ngakho sonke esingazuza kuye?Sicela ukubhale phansi kumazwana angezansi.
Ngingathanda ukunikeza umbono ohlukile.Kuthiwani uma abantu abaningi bethanda ibhayisikili le-BB eliphansi, kodwa empeleni kungenxa yokuthi izibambo ziphansi kakhulu?Ngoba umehluko wobude phakathi kwe-BB nesibambo ubaluleke kakhulu ekuphathweni, futhi ngokubona kwami amabhayisikili amaningi aneshubhu lekhanda elifushane kakhulu (okungenani ngobukhulu obukhulu) futhi ngokuvamile lithengiswa ngaphansi kwesiqu lapho ibhayisikili lithengiswa Azikho izikhala eziningi.
Kuthiwani ngesigxobo?Ishubhu lokuqondisa elide eshubhuni lekhanda elifushane libangela ukunwebeka okwengeziwe.Ukushintsha isibambo sobude kwandisa "isitaki" ngaphandle kokuthinta ukugoba kweshubhu lokuqondisa.
Yebo, yebo nginesiqu esingu-35mm esinama-spacers angu-35mm kanye nesiqu…kodwa ukubuyekezwa kwami ​​​​akukona mayelana nendlela yokubamba isibambo eside. Lokhu kungenxa yokuthi izibambo zebhayisikili zingase zibe phansi kakhulu, abantu bathanda i-BB ephansi ngoba ikhulisa umehluko wobude phakathi kwe-handlebar ne-BB.
I-BB iyashintsha ngesikhathi sokusetha ukumiswa.Umgibeli usetha i-sag, engashintsha ubude nokwehla kwe-BB. Ubude be-BB buyashintsha njengoba imijikelezo yokulengiswa idlula ngokucindezelwa futhi ibophe kabusha njengoba ukumiswa kugibela, kodwa ngokuvamile ukugibela endaweni ephakeme emisiwe ngesikhathi sokusetha i-sag. cabanga ukuthi izilungiselelo ze-sag zinomthelela omkhulu (ubude, ukwehla) kunamathayi noma ama-flip chips.
Ubeka iphuzu eliqinile lokuthi i-sag inomthelela obalulekile kuzo zombili izilinganiso.Kufanele sisebenzise amaphuzu angaguquki lapho siqhathanisa amabhayisikili, futhi i-sag yawo wonke umuntu ihlukile, yingakho ngisebenzisa izinombolo ze-pre-sag.Kungaba kuhle uma zonke izinkampani nazo zabelana. ithebula lejiyomethri elina-20% kanye no-30% sag, nakuba kungase kube nabanye abagibeli abangenawo ama-balanced angaphambili nangemuva.
Umehluko ubangelwa ukuphakama kuka-bb ngokuhlobene nendawo ethinta umhlabathi nesondo, hhayi indawo ephakathi kwesondo yokuzungezisa.
Noma yiliphi inani lenombolo ye-bb drop drop iyinganekwane enakekelwa kahle okulula ukuyiqonda kunoma ubani onolwazi ngamabhayisikili amancane afana ne-bmx, i-brompton noma i-moulton.
I-BB ephansi ayisho ithubhu lesihlalo eside.Akwenzi mqondo nhlobo.Ikakhulukazi uma ukhuluma ngokulungisa ubude be-BB usebenzisa amathayi nezimfoloko njll.Ishubhu lesihlalo liwubude obungashintshi kuhlaka olunikeziwe, futhi akukho ukulungisa okuzokwelula noma kunciphise lelo shubhu lesihlalo.Yebo, uma ufinyeza imfoloko kakhulu, ishubhu yesihlalo izokhuphuka futhi umgqomo ongaphezulu osebenzayo uzoncipha kancane, kungase kudingeke ukuhambisa isihlalo emuva kumzila, bese-ke. isihlalo sehhashi sidinga ukwehliswa kancane, kodwa ayikashintshi ngempela ubude beshubhu lesihlalo.
Umbono omuhle kakhulu, ngiyabonga .Incazelo yami ingase icace kuleso sigaba.Engifuna ukukuveza ukuthi uma unjiniyela wefreyimu ewisa i-BB kuyilapho egcina ukuphakama kweshubhu lesihlalo/evula okufanayo, ishubhu yokuhlala izoba yinde. , okungadala izinkinga ngokulingana kokuthunyelwe kwe-dropper.
kulungile ngokwanele.Nakuba ngingaqiniseki ukuthi kungani kudingekile ukugcina indawo eqondile phezulu kweshubhu yesihlalo.
Amabhayisikili okuhlola ikakhulukazi, ukusetshenziswa kwawo okuvamile kusuka ku-+25 kuya ku-+120mm BB.
Eqinisweni, okwami ​​kuwumkhuba one +25 okuhloswe ukuthi iye kuqanda lapho umgibeli ekhona. Lokhu kwenzelwa ukwanelisa izimfuneko, ngoba akukho lutho olubi njengokusebenzisa imali oyisebenze kanzima ekulengiseni okungcwaba amaphedali emhlabeni. uma isusiwe ku-piste.
Ku-hardtail yangokwezifiso elandelayo, ngiqedile ifayela le-CAD, kuhlanganise nekhasi elithi "Shall".Yileyo migomo ku-BB.
Ngingathanda ukubona izilinganiso zokwehla zangempela ezivela kubagibeli bamabhayisikili ku-sag.Ukuqina kwami ​​​​kuphakathi kuka -65 kanye -75 kuye ngendawo ye-eccentric.Ngilehlisa eyami futhi ibambe ulayini kangcono emakhoneni futhi ngizizwa ngingcono. etshalwe otshanini obude.
Akulungile, kokubili kuyiqiniso.Ukwehla kwe-BB kulinganiswa ngokuhambisana nokuyeka, usayizi wesondo awukushintshi lokhu, nakuba ubude befoloko buyakushintsha.Ubude be-BB bulinganiswa ukusuka phansi futhi buzokhuphuka noma hle njengoba usayizi wesondo ushintsha.Yingakho amabhayisikili amakhulu anamasondo bavame ukuba nokwehla kwe-BB okwengeziwe, ngakho ukuphakama kwabo kwe-BB kuyefana namabhayisikili amancane anamasondo.
Faka i-imeyili yakho ukuze uthole izindaba ezihamba phambili zokuhamba ngebhayisikili ezintabeni, kanye nokukhethwa kwemikhiqizo namadili alethwa ebhokisini lakho lokungenayo masonto onke.
