Imboni yamabhayisikili iqhubeka nokuthuthukisa ubuchwepheshe obusha bamabhayisikili kanye nokusungula izinto ezintsha. Ingxenye enkulu yale ntuthuko inhle futhi ekugcineni yenza amabhayisikili ethu akwazi futhi abe mnandi ukuwagibela, kodwa akunjalo ngaso sonke isikhathi. Umbono wethu wakamuva ngezinkinga zobuchwepheshe uwubufakazi.
Kodwa-ke, izinhlobo zamabhayisikili zivame ukwenza kahle, mhlawumbe kakhulu kunamabhayisikili angaphandle komgwaqo, manje angafani nalawo esasiwagibela eminyakeni eyishumi edlule.
Kulokho okungaba yinkukhu noma iqanda, umjaho wamabhayisikili asezintabeni onqamula izwe usube ngobuchwepheshe futhi ushesha kakhulu - njengoba umjikelezo we-Izu wokuhlola kuma-Olimpiki aseTokyo ka-2020 ufakazela - futhi amabhayisikili aseye aba maningi. Ikhono, nombono omangalisayo ushesha kakhulu.
Cishe zonke izici ze-MTB engaphandle komgwaqo zishintshile eminyakeni eyishumi edlule, kusukela ku-geometry ye-MTB ende, ekhululekile engayinquma emagqumeni obuchwepheshe nasezindaweni ezinamadwala ngenkathi isakhuphuka ngokushesha okukhulu) kuya esibambo esibanzi njengaleso esisezimotweni ezithile. Ibhayisikili lasezintabeni lase-enduro elihle kakhulu.
Asinakusho ukuthi sidumele. Lezi zinguquko zenza ukugibela umgwaqo nokubuka ungaphandle komgwaqo kube mnandi kakhulu, futhi ngezinga elithile, zivula indlela yamabhayisikili angaphandle komgwaqo ahlanganisa izingxenye ezinhle kakhulu ze-XC namabhayisikili angaphandle komgwaqo.
Ngakho-ke, uma ucabanga ngakho konke lokho, nazi izindlela eziyisithupha amabhayisikili angaphandle komgwaqo ashintsha ngazo, nokuthi kungani kuyinto enhle kuwo wonke umuntu ohamba ngebhayisikili. Uma ufuna ukufunda kabanzi ngamabhayisikili e-XC, qiniseka ukuthi uhlola umhlahlandlela womthengi wethu wamabhayisikili angaphandle komgwaqo angcono kakhulu.
Mhlawumbe ushintsho oluphawuleka kakhulu kumabhayisikili e-XC ubukhulu bamasondo, ngamabhayisikili asezintabeni angaphandle komgwaqo wonke asebenzisa amasondo angu-29 intshi.
Uma ngibheka emuva eminyakeni eyi-10, ngenkathi abagibeli abaningi beqala ukuqaphela izinzuzo zama-intshi angu-29, abaningi basaqhubeka nokunamathela ngenkani kuma-intshi amancane, futhi kuze kube yileso sikhathi, usayizi ojwayelekile wama-intshi angu-26.
Manje, lokho kuzoncika nasezidingweni zoxhaso. Uma umxhasi wakho engafiki ku-29er, awukwazi ukuyigibela noma ngabe ubufuna. Kodwa kungakhathaliseki ukuthi kwenzekani, abashayeli abaningi bayakujabulela ukunamathela kulokho abakwaziyo.
Futhi, banesizathu esihle. Kuthathe imboni yamabhayisikili isikhathi eside ukuthola i-geometry kanye nezingxenye ze-29ers ngendlela efanele. Amasondo angaba buthaka, futhi ukuphathwa kwawo kungashiya okuncane okufiselekayo, ngakho-ke akumangalisi ukuthi abanye abagibeli bayangabaza.
Kodwa-ke, ngo-2011, waba ngumgibeli wokuqala ukuwina iNdebe Yomhlaba yeCross Country ngebhayisikili elingamasentimitha angu-29. Wabe esewina indondo yegolide yama-Olympic aseLondon ngo-2012 ku-29er (Specialized S-Works Epic). Kusukela ngaleso sikhathi, amasondo angamasentimitha angu-29 kancane kancane abe yinto evamile emijahweni ye-XC.
Masinyane kuze kube manje, futhi iningi labagibeli lingavumelana ngezinzuzo zamasondo angu-29 intshi omjaho we-XC. Agingqika ngokushesha, anikeza ukubamba okwengeziwe futhi andise induduzo.
Olunye ushintsho olukhulu ngamabhayisikili angcolile (kanye namabhayisikili asezintabeni ngokuvamile) kwaba ukufika kwama-kit amabhayisikili asezintabeni anegiya, i-chainring ngaphambili kanye nekhasethi ebanzi ngemuva, ngokuvamile i-10 encane kolunye uhlangothi. I-Tooth sprocket ene-sprocket enkulu enamazinyo angu-50 kolunye uhlangothi.
Akudingeki ukuthi uye kude kakhulu ukuze ubone ibhayisikili elihamba ngomgwaqo eline-crankset ezintathu ngaphambili. Ilungu leqembu leBikeRadar likhumbula ibhayisikili labo lokuqala elihamba ngomgwaqo, elaphuma ngo-2012, line-crankset ezintathu.
Ama-chainring amathathu namabili anganikeza umgibeli ububanzi obuhle bamagiya kanye nesikhala esifanelekile ukuze kube ne-cadence ephelele, kodwa futhi kunzima kakhulu ukuwagcina nokusebenza kahle.
Njenganoma yikuphi ukusungula izinto ezintsha, lapho kukhishwa i-gear yayo eyodwa ngo-2012, abagibeli abaningi babengaqiniseki ngoba ukuhlakanipha okuvamile kwakuwukuthi amagiya ayi-11 ngeke asebenze ngempela emzileni ongaphandle komgwaqo.
Kodwa kancane kancane, ochwepheshe kanye nabantu abathanda ukuzilibazisa baqala ukuqaphela izinzuzo zokushayela ngakunye. Izitimela zokushayela kulula ukuzifaka, kulula ukuzinakekela nokunciphisa isisindo ngenkathi ugcina ibhayisikili lakho libukeka lihlanzekile. Futhi kwenza abenzi bamabhayisikili bakwazi ukwakha amabhayisikili angcono aqinile ngoba akukho mingcele yangaphambili yokwenza isikhala somshini wokushaqeka wangemuva.
Ukweqa phakathi kwezilinganiso zamagiya kungaba kukhulu kancane, kodwa kuvela ukuthi akekho onendaba noma odinga isikhala esincane esinikezwa yizindandatho ezimbili noma ezintathu.
Uma siya kunoma yimuphi umjaho ongaphandle komgwaqo namuhla, sisola ukuthi ibhayisikili ngalinye lizoba yi-cog, okuyinto enhle ngombono wethu.
Ijiyometri iyisibonelo esihle sendlela ubuchwepheshe bokugibela ibhayisikili obungahambisana ngayo nezidingo zesiyalo futhi buqhubeke buthuthuka. Njengoba ukugijima ngaphandle komgwaqo sekuye kwaba nzima futhi kwaba nobuchwepheshe, izinkampani ziye zathuthuka ngokwenza amabhayisikili azo afaneleke kakhulu ekwehleni ngenkathi zisaqhubeka nokusebenza ngokukhuphuka.
Isibonelo esiyinhloko se-geometry yesimanje yamabhayisikili angaphandle komgwaqo yi-Specialized Epic yakamuva, echaza ukuthi ingakanani imishini engaphandle komgwaqo eshintshile.
I-Epic ilungele izidingo zesivinini esiphezulu nezobuchwepheshe zesimanje ezingaphandle komgwaqo. Ine-engeli yekhanda engu-67.5 degrees ethambile, kanye ne-engeli yesihlalo engu-470mm ende (ebukekayo) engu-75.5 degrees. Zonke izinto ezinhle uma uphedula futhi wehla ngokushesha.
I-Epic ka-2012 ibukeka njengeyesikhathi eside uma iqhathaniswa nenguqulo yesimanje. I-engeli ye-head tube engu-70.5-degree yenza ibhayisikili libukhali ngokujika, kodwa futhi liyenza ingaqiniseki ngokwehla.
Ukufinyelela kufushane futhi ku-438mm, kanti i-engeli yesihlalo iyancipha kancane ku-74 degrees. I-engeli yesihlalo ekhululekile ingenza kube nzima ngawe ukuthola indawo ephumelelayo yokunyathela i-bracket engezansi.
Ngokufanayo, elisha linye ibhayisikili le-XC elinesimo sokwakheka esishintshile. I-engeli yeshubhu yekhanda iphansi ngamadigri angu-1.5 kunemodeli yangaphambilini, kuyilapho i-engeli yesihlalo iphakeme ngamadigri angu-1.
Kuyafaneleka ukuqaphela ukuthi sidweba imigqa ebanzi lapha. Ngaphezu kwezibalo zejiyometri esizishoyo lapha, kunezinye izibalo eziningi nezici ezithinta indlela ibhayisikili elisebenza ngayo emgwaqweni, kodwa akunakuphikwa ukuthi i-jiyometri yesimanje ye-XC ishintshile ukuze yenze la mabhayisikili angabi namahloni lapho ehla entabeni.
Sisola ukuthi uma utshela noma yimuphi umgibeli wama-Olympic ka-2021 ukuthi kuzodingeka agijime ngenjoloba encane, uzocasuka kakhulu. Kodwa ukuhlehlisa amathayi eminyaka engu-9 namancane kuyinto evamile, futhi ophumelele ngo-2012 ufika namathayi angu-2 intshi.
Eminyakeni eyishumi edlule, kube nomkhuba obanzi wamathayi kulo lonke izwe lokugibela amabhayisikili, kusukela ekugibeleni emgwaqweni kuya ku-XC, futhi amathayi amahle kakhulu ebhayisikili lasezintabeni namuhla aqinile impela.
Ukuhlakanipha okuvamile kwakuwukuthi amathayi amancane agijima ngokushesha futhi asindise isisindo sakho. Womabili abalulekile ekugijimeni ngaphandle komgwaqo, kodwa yize amathayi amancane engakugcinela isisindo, amathayi abanzi angcono cishe ngazo zonke izindlela.
Zigingqika ngokushesha, zibamba kakhulu, zinikeza induduzo eyengeziwe, futhi zinganciphisa amathuba okubhoboka kungakabi yisikhathi. Konke kuhle kumuntu osafufusa ogijima ngaphandle komgwaqo.
Kusenempikiswano ethile mayelana nokuthi yiliphi ithayi elishesha kakhulu, futhi kungenzeka kungabi khona impendulo ecacile yalowo mbuzo. Kodwa okwamanje, iningi labagibeli libonakala likhetha amathayi angu-2.3 intshi noma angu-2.4 intshi emijahweni ye-XC.
Saze sazihlola nobubanzi bamathayi, sihlola osayizi bamathayi abasheshayo bamabhayisikili asezintabeni kanye nomthamo wamathayi osheshayo wangaphandle komgwaqo. Uma uzilinganisela wena, qiniseka ukuthi ufunda nomhlahlandlela wethu wokucindezela amathayi we-MTB.
Njengoba othile eshilo ku-movie mayelana nezicabucabu, “ngamandla amakhulu kuza umthwalo wemfanelo omkhulu” futhi kunjalo nangamabhayisekili anamuhla angaphandle komgwaqo.
Amathayi akho alungiselelwe kahle, i-geometry kanye nosayizi wamasondo kukunika ithuba lokuhamba ngokushesha kunanini ngaphambili. Kodwa udinga ukwazi ukulawula lawo mandla - futhi ngalokho, uzodinga izibambo ezibanzi.
Futhi, akudingeki uye kude kakhulu ukuze ubone ibhayisikili elinesibambo esincane kune-700mm. Uma ubheka emuva, liqala ngisho nokucwila ngaphansi kwe-600mm.
Kulesi sikhathi semigoqo ebanzi, ungase uzibuze ukuthi kungani umuntu ayengagibela ububanzi obuncane kangaka? Nokho, isivinini sasivame ukuba sincane ngaleso sikhathi, futhi ukwehla kwakungadingi ubuchwepheshe obutheni. Futhi, kuyinto abantu abayisebenzisa ngaso sonke isikhathi, kungani beyishintsha?
Ngenhlanhla kithi sonke, njengoba isivinini sikhuphuka, nobubanzi bezibambo zethu buyanda, futhi amabhayisikili amaningi e-XC agcwele izibambo ezingu-740mm noma ezingu-760mm okwakungacatshangwa eminyakeni eyishumi edlule.
Njengamathayi abanzi, izibambo ezibanzi seziyinto evamile kuyo yonke indawo yamabhayisikili asezintabeni. Zikunikeza ukulawula okwengeziwe ezigabeni zobuchwepheshe futhi zingathuthukisa ukulingana kwebhayisikili, futhi abanye abagibeli banomuzwa wokuthi ububanzi obengeziwe buyasiza ekuvuleni isifuba sokuphefumula.
Ukumiswa kwemoto kukhuphuke kakhulu eminyakeni eyishumi edlule noma ngaphezulu. Kusukela ekukhiyeni kukagesi kweFox kuya ekushayweni okulula nokukhululekile, akungabazeki ukuthi amabhayisikili anamuhla akhululekile kakhulu endaweni ende noma eyinkimbinkimbi.
Lokhu kuthuthukiswa kobuchwepheshe bokumisa, kanye neqiniso lokuthi ithrekhi inobuchwepheshe kakhulu kunanini ngaphambili, kusho ukuthi kungenzeka ukuthi ubone ibhayisikili elimiswe ngokuphelele kunebhayisikili eliqinile emjahweni we-XC ohamba phambili.
Ama-Hardtails alungele izinkundla esazibona emgwaqweni ongaphandle kweminyaka eyishumi noma ngaphezulu edlule. Manje konke sekushintshile. Nakuba i-Hardtail ingenye yezinkundla zobuchwepheshe obuncane kumjikelezo weNdebe Yomhlaba wamanje, futhi iphakamisa umbuzo wokuthi ngabe kufanele sikhethe i-hardtail noma ibhayisikili eliyi-full suspension (uVictor uwine i-2021 Men's Classic nge-hardtail, wawina i-full suspension yomjaho wabesifazane), iningi labagibeli manje likhetha zombili iziphetho emijahweni eminingi.
Ungasiqondi kahle, kusenezinqola eziqinile ezishesha kakhulu ku-XC—i-BMC eyethulwe ngonyaka odlule iwubufakazi bokuthi izimoto eziqinile ezisebenza ngaphandle komgwaqo ziyathuthuka—kodwa amabhayisikili acinyiwe ngokuphelele manje asebusa kakhulu.
Ukuhamba nakho kuya ngokuya kuthuthuka. Thatha iScott Spark RC entsha - ibhayisikili olithandayo. Linokuhamba okungu-120mm ngaphambili nangemuva, kanti sesijwayele ukubona okungu-100mm.
Yiziphi ezinye izinto esizibonile kubuchwepheshe bokumisa? Thatha i-Brain Suspension enelungelo lobunikazi le-Specialized, isibonelo. Umklamo usebenza kusetshenziswa i-inertia valve, evala ngokuzenzakalelayo i-suspension yakho endaweni eyisicaba. Uma ushaya i-bump bese i-valve ivula i-suspension ngokushesha futhi. Empeleni, kungumqondo omuhle kakhulu, kodwa empeleni, ukuphindaphinda kwasekuqaleni kunikeze ubuchopho abalandeli bomhlaba.
Isikhalazo esikhulu kwakuwukubhonga okukhulu noma ukubhonga okwakuzwakala umgibeli lapho ivalvu ivuleka futhi. Awukwazi futhi ukulungisa ukuzwela kobuchopho bakho ngesikhathi ushayela, okuyinto engeyinhle uma ugibela endaweni ehlukile.
Kodwa-ke, njengakho konke okukulolu hlu, i-Specialized iye yathuthukisa ubuchopho kancane kancane eminyakeni edlule. Manje ingalungiswa ngokushesha, futhi umsindo oshayayo, yize usekhona, uthambile kakhulu kunezizukulwane zangaphambilini.
Ekugcineni, ukuvela kokushaqeka kuyisibonelo esihle sendlela amabhayisikili e-XC anamuhla aklanywe ngayo ukuba abe namandla futhi asebenziseke kalula kunanini ngaphambili.
Ubelokhu encintisana emiqhudelwaneni eyahlukene iminyaka engaphezu kweyishumi, okuhlanganisa ukuwela izintaba, i-marathon kanye nokukhuphuka izintaba, futhi manje ujabulela impilo yokuzola, ukuma emakhefini nokuphuza ubhiya ngemva kokugibela ibhayisikili. Nakuba umndeni omncane usho ukuthi unesikhathi esincane sokuphumula, usajabulela ukukhuphuka intaba nokuhlupheka lapho egibela. Njengomsekeli oqinile wokugibela ibhayisikili lezintaba eliqinile emgwaqweni, ungase uthole nokugibela isithandwa sakhe njengoba ilanga lishona.
Ngokufaka imininingwane yakho, uvumelana neMigomo Nemibandela yeBikeRadar kanye neNqubomgomo Yobumfihlo. Ungazikhipha ohlwini nganoma yisiphi isikhathi.
