Ishishini leebhayisekile lihlala liphucula ubuchwepheshe obutsha beebhayisekile kunye nezinto ezintsha. Uninzi lwale nkqubela phambili lulungile kwaye ekugqibeleni lwenza iibhayisekile zethu zibe nobuchule ngakumbi kwaye zibe mnandi ukuzikhwela, kodwa oko akusoloko kunjalo. Imbono yethu yakutshanje ngetekhnoloji engapheliyo ibubungqina.
Nangona kunjalo, iimpawu zeebhayisekile zihlala zichanekile, mhlawumbi ngaphezu kweebhayisekile ezisebenzisa iindlela ezingaqhelekanga, ngoku ezingafaniyo nezo besiziqhuba kwiminyaka elishumi eyadlulayo.
Kwinto enokuba yinkukhu okanye iqanda, umdyarho weebhayisekile zeentaba onqumla ilizwe uye waba ngobuchule kwaye ukhawuleza ngakumbi - njengoko umjikelo wovavanyo lwe-Izu kwiOlimpiki zaseTokyo zika-2020 ubonisa - kwaye iibhayisekile ziye zaba ngcono. Ubuchule, ewe, umbono ongaqhelekanga nawo ukhawuleza.
Phantse yonke into ye-MTB engaphandle kwendlela itshintshile kwiminyaka elishumi edlulileyo, ukusuka kwi-geometry ye-MTB ende, ekhululekileyo enokuyinqumla kwiinduli zobugcisa kunye neendawo ezinamatye ngelixa isakhawuleza ngokukhawuleza ukunyuka intaba) ukuya kwisiphatho esibanzi njengale kwiimoto ezithile. Eyona bhayisekile yentaba ye-enduro ilungileyo.
Asinakuthi siphoxekile. Olu tshintsho lwenza ukuba ukukhwela umgama ongekho ndleleni kunye nokubukela kube mnandi ngakumbi, kwaye kwinqanaba elithile, kuvula indlela yeebhayisekile ezingekho ndleleni ezidibanisa iindawo ezilungileyo ze-XC kunye neebhayisekile ezingekho ndleleni.
Ngoko ke, xa ucinga ngako konke oko, nazi iindlela ezintandathu ezitshintsha ngazo iibhayisekile ezingaphandle kwendlela, kwaye kutheni kuyinto elungileyo kuye wonke umntu ohamba ngebhayisekile. Ukuba ufuna ukufunda okungakumbi ngeebhayisekile ze-XC, qiniseka ukuba ujonge isikhokelo somthengi wethu kwiibhayisekile ezilungileyo ezingaphandle kwendlela.
Mhlawumbi utshintsho oluphawulekayo kwiibhayisekile ze-XC bubungakanani bamavili, kunye neebhayisekile zasezintabeni ezingaphandle kwendlela zonke zisebenzisa amavili angama-29 intshi.
Xa ndijonga emva kwiminyaka eli-10, ngelixa abakhweli abaninzi beqala ukuqonda iingenelo zee-intshi ezingama-29, uninzi lwabo lusaqhubeka ngenkani noluncinci, kwaye kude kube ngoko, ubungakanani obuqhelekileyo buzii-intshi ezingama-26.
Ngoku, oko kuya kuxhomekeka kwiimfuno zoxhaso. Ukuba umxhasi wakho akafiki kwi-29er, awunakuyikhwela nokuba ubufuna. Kodwa nokuba kwenzeka ntoni na, abaqhubi abaninzi bayakuvuyela ukunamathela kwinto abayaziyo.
Kwaye, banesizathu esivakalayo. Kuthathe ixesha elide kushishino lweebhayisekile ukulungisa ijiyometri kunye nezinto ze-29ers. Amavili anokuba buthathaka, kwaye ukuphathwa kwawo kungashiya kancinci ukuba kufuneke, ngoko ke akumangalisi ukuba abanye abakhweli bathandabuze.
Nangona kunjalo, ngo-2011, waba ngumkhweli wokuqala ukuphumelela iNdebe yeHlabathi yeCross Country ekhwele ibhayisekile engama-intshi angama-29. Emva koko waphumelela imbasa yegolide ye-cross-country kwi-Olimpiki yaseLondon ka-2012 kwi-29er (Specialized S-Works Epic). Ukusukela ngoko, amavili angama-intshi angama-29 aye aba yinto eqhelekileyo kumdyarho we-XC.
Sijonge phambili ngoku, kwaye uninzi lwabakhweli lungavumelana ngeenzuzo zamavili angama-29 intshi kumdyarho we-XC. Aqengqeleka ngokukhawuleza, anika amandla okubamba ngakumbi kwaye andise intuthuzelo.
Olunye utshintsho olukhulu kwiibhayisekile zothuli (kunye neebhayisekile zasezintabeni ngokubanzi) yayikukufika kweekiti zeebhayisekile zasezintabeni ezinegiya, ikhonkco ngaphambili kunye nekhasethi ebanzi ngasemva, idla ngokuba yi-10 encinci kwelinye icala. I-Tooth sprocket kunye ne-sprocket enkulu enamazinyo angama-50 kwelinye icala.
Akunyanzelekanga ukuba uye kude kakhulu ukuze ubone ibhayisekile yomzila ene-triple crankset ngaphambili. Ilungu leqela leBikeRadar likhumbula ibhayisekile yabo yokuqala engekho endleleni, eyaphuma ngo-2012, ine-triple crankset.
Iintambo ezintathu kunye neentambo ezimbini zinokunika umkhweli uluhlu olufanelekileyo lweegiya kunye nendawo efanelekileyo ukuze ahambe kakuhle, kodwa kunzima ngakumbi ukuzigcina zikwimeko entle yokusebenza.
Njengakwezinye izinto ezintsha, xa yakhutshwa indlela yayo yokutshintsha imoto ngo-2012, abakhweli abaninzi babengaqinisekanga kuba ubulumko obuqhelekileyo yayikukuba iigiya ezili-11 azizukusebenza kakuhle kumzila ongekho endleleni.
Kodwa kancinci kancinci, iingcali kunye nabantu abathanda izinto zokuzonwabisa baqala ukuqonda iingenelo zokufaka iimoto nganye nganye. Ii-Drivetrains kulula ukuzifaka, kulula ukuzigcina kwaye zinciphisa ubunzima ngelixa zigcina ibhayisekile yakho ibukeka icocekile. Ikwavumela abenzi beebhayisekile ukuba bakhe iibhayisekile ezixhonyiweyo ngokupheleleyo kuba akukho ndawo ingaphambili enokubangela ukuba kubekho indawo yoxinzelelo lwangasemva.
Ukunyuka phakathi kwemilinganiselo yegiya kunokuba kukhulu kancinci, kodwa kuvela ukuba akukho mntu ukhathalayo okanye ofuna isithuba esincinci esibonelelwa zii-chainrings ezimbini okanye ezintathu.
Ukuya kulo naliphi na igqatso elingekho semgaqweni namhlanje, sicinga ukuba yonke ibhayisekile iza kuba yi-cog, nto leyo ilungileyo ngokoluvo lwethu.
Ijiyometri ngumzekelo omhle wendlela iteknoloji yokukhwela ibhayisekile enokuhambisana ngayo neemfuno zoqeqesho kwaye iqhubeke iphucuka. Njengoko ukubaleka ngaphandle kwendlela kuye kwaba nzima kwaye kunobuchwephesha ngakumbi, iimpawu ziye zatshintsha ngokwenza iibhayisekile zazo zilungele ukwehla ngelixa zisaqhubeka nokusebenza ngokunyuka.
Umzekelo obalaseleyo wejiyometri yanamhlanje yeebhayisekile ezisebenzisa indlela engaqhelekanga yiSpecialized Epic yamva nje, echaza indlela ezitshintshe ngayo izixhobo ezisebenzisa indlela engaqhelekanga.
I-Epic ifanelekile kwiimfuno zesantya esiphezulu nezobuchwephesha zendlela yanamhlanje. Ine-engile yentloko ethe tyaba engama-67.5 degrees, kunye ne-engile yesihlalo esiphakamileyo engama-470mm (encinci) engama-75.5 degrees. Zonke izinto ezilungileyo xa ukhwela okanye uhla ngokukhawuleza.
I-Epic ka-2012 ibukeka njengeyakudala xa ithelekiswa nenguqulelo yanamhlanje. I-engile yetyhubhu yentloko engama-70.5-degree yenza ibhayisekile ibe bukhali xa ijikajika, kodwa ikwayenza ingazithembi ukuba yehla njani.
Ukufikelela kufutshane kwi-438mm, kwaye i-engile yesihlalo incinci kancinci kwi-74 degrees. I-engile yesihlalo ekhululekileyo ingenza kube nzima kuwe ukufumana indawo efanelekileyo yokunyathela kwi-bracket esezantsi.
Ngokufanayo, entsha yibhayisekile ye-XC enejiyometri etshintshileyo. I-engile yetyhubhu yentloko icotha nge-1.5 degrees kunemodeli yangaphambili, ngelixa i-engile yesihlalo inyuka nge-1 degree.
Kubalulekile ukuqaphela ukuba sidweba imigca etyebileyo apha. Ukongeza kwimifanekiso yejiyometri esiyikhankanyayo apha, kukho eminye imifanekiso emininzi kunye nezinto ezichaphazela indlela ephatha ngayo ibhayisekile engaphandle kwendlela, kodwa akukho kuphikiswa ukuba ijiyometri yanamhlanje ye-XC iguqukile ukuze yenze ezi bhayisekile zingabi nantloni xa zikhwela zisihla entabeni.
Sicinga ukuba ukuba uxelele nabani na oqhuba iiOlimpiki zika-2021 ukuba kuya kufuneka abaleke ngerabha encinci, baya kucaphuka kakhulu. Kodwa ukuphinda ubuye emva kweminyaka eli-9 kunye namatayara amancinci kuqhelekile, kwaye ophumeleleyo ka-2012 uza namatayara angama-intshi amabini.
Kwiminyaka elishumi edlulileyo, kubekho umkhwa obanzi kwiitayara kulo lonke ilizwe lokukhwela ibhayisekile, ukusuka ekukhweleni ngemoto ukuya kwi-XC, kwaye amatayara eebhayisekile zeentaba angcono kakhulu namhlanje aqinile kakhulu.
Ubulumko obuqhelekileyo babusithi amatayara amancinci aqengqeleka ngokukhawuleza aze akugcinele ubunzima obuncinci. Omabini abalulekile ekubalekeni ngaphandle kwendlela, kodwa nangona amatayara amancinci enokukongela ubunzima, amatayara abanzi angcono phantse ngazo zonke iindlela.
Ziqengqeleka ngokukhawuleza, zibambe ngakumbi, zinike intuthuzelo engaphezulu, kwaye zinokunciphisa amathuba okubhoboka ngexesha elingafanelekanga. Konke kulungile kumqhubi osaqalayo ohamba ngaphandle kwendlela.
Kusekho ingxoxo-mpikiswano malunga nokuba leliphi itayara elikhawulezayo, kwaye kusenokungabikho mpendulo icacileyo kuloo mbuzo. Kodwa okwangoku, uninzi lwabakhweli lubonakala lukhetha amatayara angama-2.3 intshi okanye angama-2.4 intshi kumdyarho we-XC.
Side sazivavanya nobubanzi bamatayara, sihlola ubungakanani bamatayara akhawulezayo kwiibhayisekile zasezintabeni kunye nomthamo wamatayara akhawulezayo kwiindawo ezingaphandle kwendlela. Ukuba uzilinganisela ngokwakho ubungakanani bamatayara, qiniseka ukuba uyasifunda nesikhokelo sethu soxinzelelo lwamatayara e-MTB.
Njengoko umntu othile watshoyo kwimuvi malunga nezigcawu, “amandla amakhulu azisa uxanduva olukhulu” kwaye kunjalo nakwiibhayisekile zanamhlanje ezisebenzisa iindlela ezingaqhelekanga.
Amatayara akho alungisiweyo, ijiyometri kunye nobukhulu bamavili kukunika ithuba lokuhamba ngokukhawuleza kunangaphambili. Kodwa kufuneka ukwazi ukulawula loo mandla - kwaye ngenxa yoko, kuya kufuneka ube neebhanti ezibanzi.
Kwakhona, akufuneki uye kude kakhulu ukuze ubone ibhayisekile enesiphatho esincinci kune-700mm. Xa ujonga ngasemva, ziqala ukuntywila ngaphantsi kwe-600mm.
Kule mihla yeebhari ezibanzi, usenokuba uzibuza ukuba kutheni umntu ebenokukhwela ububanzi obuncinci kangaka? Kaloku, isantya sasisoloko sicotha ngelo xesha, kwaye ukwehla kwakungathethi kakhulu. Kwakhona, yinto abantu abayisebenzisayo rhoqo, kutheni beyitshintsha?
Ngethamsanqa kuthi sonke, njengoko isantya sinyuka, nobubanzi beebhari zethu ze-XC buyakhula, kwaye iibhayisekile ezininzi ze-XC zigcwele iibhari ze-740mm okanye ze-760mm ebezingenakucingelwa kwiminyaka elishumi eyadlulayo.
Njengamatayara abanzi, iihandlebars ezibanzi ziye zaba yinto eqhelekileyo kuyo yonke indawo yokukhwela ibhayisekile yasezintabeni. Zikunika ulawulo oluthe kratya kwiindawo zobugcisa kwaye zinokuphucula ukulingana kwebhayisekile, kwaye abanye abakhweli bavakalelwa kukuba ububanzi obongezelelweyo bunceda ukuvula isifuba ukuze uphefumle.
Le suspension iye yanda kakhulu kwiminyaka elishumi edlulileyo okanye ngaphezulu. Ukususela kwi-electric locking yeFox ukuya kwi-shocks ezikhaphukhaphu nezikhululekileyo, akukho mathandabuzo ukuba iibhayisekile zanamhlanje zikhululekile ngakumbi kumhlaba othe nkqo okanye ochwephesha.
Olu phuculo kwitekhnoloji yokumiswa, kunye nenyani yokuba umzila ungowobuchwephesha ngakumbi kunangaphambili, kuthetha ukuba kunokwenzeka ukuba ubone ibhayisekile exhonywe ngokupheleleyo kune-hardtail kumdyarho we-XC ophezulu.
IiHardtails zilungele iikhosi esizibonileyo kwiindawo ezingaphandle kwendlela kwiminyaka elishumi okanye ngaphezulu eyadlulayo. Ngoku yonke into itshintshile. Nangona i-Hardtail yenye yezona khosi zingekho zobugcisa kangako kwiNdebe yeHlabathi yangoku, kwaye iphakamisa umbuzo wokuba kukhethwe ibhayisekile yeHardtail okanye yeSuspension epheleleyo (uVictor uphumelele i-2021 Men's Classic ngeHardtail, waphumelela iSuspension epheleleyo yomdyarho wabasetyhini), uninzi lwabakhweli ngoku bakhetha zombini iziphelo kwimidyarho emininzi.
Ungasiqondi kakuhle, kusekho ii-hardtails ezikhawulezayo kwi-XC—i-BMC eyaziswa kunyaka ophelileyo bubungqina be-hardtails eziqhubekekayo endleleni—kodwa iibhayisekile ezixhonywe ngokupheleleyo ngoku zilawula kakhulu.
Ukuhamba kuya kusiba nempumelelo ngakumbi. Thatha iScott Spark RC entsha – ibhayisekile ekhethwayo. Ine-120mm yokuhamba ngaphambili nangasemva, ngelixa siqhele ukubona i-100mm.
Zeziphi ezinye izinto esizibonileyo kubuchwepheshe bokuxhoma? Umzekelo, thatha i-Specialized's patented Brain Suspension. Olu yilo lusebenza kusetyenziswa ivalvu ye-inertia, evala ngokuzenzekelayo i-suspension yakho kwindawo ethe tyaba. Xa ubetheka i-bump, ivalvu ivula i-suspension kwakhona ngokukhawuleza. Ngokomgaqo, ngumbono ogqwesileyo, kodwa ekusebenzeni, ukuphindaphinda kwasekuqaleni kunike ubuchopho abalandeli bomhlaba.
Eyona sikhalazo sikhulu yayikukugquma okanye ukugquma okukhulu komkhweli xa ivalvu ivuleka kwakhona. Awunakukwazi nokulungisa indlela ingqondo yakho evakalelwa ngayo xa ubhabha, into engentle ukuba ukhwele kwiindawo ezahlukeneyo.
Nangona kunjalo, njengayo yonke into ekolu luhlu, iSpecialized iye yaphucula ingqondo kancinci kancinci kule minyaka idlulileyo. Ngoku ingalungiswa ngokukhawuleza, kwaye isandi esivakalayo, nangona sisasebenza, sithambile kakhulu kunezizukulwana zangaphambili.
Ekugqibeleni, ukuguquka komothuko ngumzekelo ophambili wendlela iibhayisekile ze-XC zanamhlanje eziyilwe ngayo ukuba zibe namandla kwaye zisebenziseke ngakumbi kunangaphambili.
Ubekhuphisana kwiminyhadala eyahlukeneyo kangangeminyaka engaphezu kweshumi, kuquka ukunqumla ilizwe, i-marathon kunye nokunyuka iintaba, kwaye ngoku uyonwabela ubomi bokuphumla, ukuma kwiikhefi nokusela ubhiya emva kokukhwela ibhayisekile. Nangona usapho olutsha luthetha ukuba akanalo ixesha elininzi lokuphumla, usakonwabela ukunyuka intaba kwaye usokola xa ekhwela. Njengomxhasi oqinileyo we-hardtail mountain biking endleleni, unokufumana ukukhwela isithandwa sakhe njengoko ilanga litshona.
Ngokufaka iinkcukacha zakho, uyavuma iMigqaliselo neMiqathango yeBikeRadar kunye noMgaqo-nkqubo waBucala. Ungazikhupha nanini na.
