Makampani opanga njinga nthawi zonse akupita patsogolo luso latsopano la njinga ndi zatsopano.Zambiri za kupita patsogolo kumeneku ndi zabwino ndipo potsirizira pake zimapangitsa kuti njinga zathu zikhale zokhoza komanso zosangalatsa kukwera, koma sizili choncho nthawi zonse.Maonedwe athu aposachedwapa a teknoloji yakufa-mapeto ndi umboni.
Komabe, mitundu yanjinga nthawi zambiri imakhala yabwino, mwina kuposa njinga zapamsewu, zomwe sizikuwoneka ngati zomwe tidakwera zaka khumi zapitazo.
M'malo omwe angakhale nkhuku-kapena-dzira, mpikisano wa njinga zamapiri odutsa dziko wakhala waukadaulo komanso wachangu - monga momwe mayeso a Izu pamasewera a Olimpiki a Tokyo a 2020 akutsimikizira - ndipo njinga zakhala zochulukira. mofulumira kwambiri.
Pafupifupi mbali zonse za MTB zapamsewu zasintha mzaka khumi zapitazi, kuchokera ku nthawi yayitali, yotayirira ya MTB geometry yomwe ingathe kuidula pamitsinje yamatekinoloje ndi magawo amiyala pomwe imakhala yothamanga kwambiri kukwera phiri) kupita ku chogwirizira chotalikirapo ngati chomwe chilipo. ena magalimoto.The yabwino Enduro phiri njinga.
Sitinganene kuti tinakhumudwitsidwa.Zosinthazi zimapanga kukwera kwapamsewu ndikuwonera kosangalatsa kwambiri ndipo, pang'onopang'ono, kumayendetsa njinga zamoto zomwe zimagwirizanitsa mbali zabwino kwambiri za XC ndi njinga zapamsewu.
Choncho, poganizira zonsezi, apa pali njira zisanu ndi imodzi zomwe njinga zapamsewu zimasinthira, komanso chifukwa chake ndi chinthu chabwino kwa aliyense woyendetsa njinga. njinga zabwino kwambiri zapamsewu.
Mwina kusintha kodziwika kwambiri mu njinga za XC ndi kukula kwa mawilo, okhala ndi njinga zam'mapiri zakutali zonse zimagwiritsa ntchito mawilo 29 inchi.
Kuyang'ana m'mbuyo zaka 10, pamene okwera ambiri akuyamba kuzindikira ubwino wa mainchesi 29, ambiri amamatirabe ndi ang'onoang'ono, ndipo mpaka nthawiyo, kukula kwake 26 mainchesi.
Tsopano, izo zidzadaliranso zofunikira zothandizira.Ngati wothandizira wanu sapanga 29er, simungathe kukwera ngakhale mutafuna.Koma ziribe kanthu, madalaivala ambiri amasangalala kumamatira ku zomwe akudziwa.
Ndipo, ali ndi zifukwa zomveka.Zinatengera makampani a njinga kwa nthawi kuti apeze geometry ya 29ers ndi zigawo zake zolondola.Mawilo amatha kukhala aang'ono, ndipo kugwiritsira ntchito kumatha kuchoka pang'ono, kotero n'zosadabwitsa kuti okwera ena amakayikira.
Komabe, mu 2011, anali wokwera woyamba kuti apambane Cross Country World Cup pa njinga ya inchi 29. Kenaka adagonjetsa ndondomeko ya golidi ya 2012 London Olympics mu 29er (Specialized S-Works Epic) .Kuyambira pamenepo, 29 -mawilo inchi pang'onopang'ono asanduka chizolowezi mu mpikisano XC.
Mofulumira mpaka pano, ndipo okwera ambiri angagwirizane pa ubwino wa mawilo a 29-inch kwa XC racing. Iwo amagudubuza mofulumira, amapereka zowonjezereka ndikuwonjezera chitonthozo.
Kusintha kwina kwakukulu kwa njinga zamoto (ndi njinga zamapiri) kunali kubwera kwa zida za njinga zamapiri ndi gearing, chainring kutsogolo ndi makaseti osiyanasiyana kumbuyo, kawirikawiri 10 yaing'ono pa mapeto amodzi Tooth sprocket ndi yaikulu. 50-mano sprocket mbali ina.
Simuyenera kupita patali kwambiri kuti muwone njinga yamtunda yokhala ndi crankset katatu kutsogolo.Mmodzi wa gulu la BikeRadar amakumbukira njinga yawo yoyamba yapamsewu, yomwe idatuluka mu 2012, yokhala ndi crankset katatu.
Maunyolo atatu ndi apawiri atha kupangitsa wokwerayo kukhala ndi magiya osiyanasiyana komanso malo abwino oti azitha kutsetsereka bwino, komanso amakhala ovuta kuwasamalira ndikugwira ntchito bwino.
Monga momwe zilili ndi zatsopano, zitatulutsidwa mu 2012, okwera ambiri sanali otsimikiza chifukwa nzeru wamba inali yakuti magiya 11 sangagwire ntchito pamsewu wakunja.
Koma pang'onopang'ono, akatswiri ndi ochita masewera olimbitsa thupi anayamba kuzindikira ubwino wa imodzi-by.Drivetrains ndi zosavuta kukhazikitsa, zosavuta kusunga ndi kuchepetsa kulemera pamene kusunga njinga yanu ikuwoneka yoyera.Imathandizanso opanga njinga kupanga njinga zabwino zoyimitsidwa zonse chifukwa pali palibe derailleur wakutsogolo kuti apangitse malo kugwedezeka kumbuyo.
Kudumpha pakati pa magiya kutha kukulirakulirapo, koma zikuwoneka kuti palibe amene amasamala kapena amafunikira malo olimba omwe maunyolo apawiri kapena atatu amapereka.
Kupita ku mpikisano uliwonse wapamsewu lero, tikukayikira kuti njinga iliyonse idzakhala cog, chomwe chiri chinthu chabwino m'malingaliro athu.
Geometry ndi chitsanzo chabwino cha momwe teknoloji yoyendetsa njinga ingagwirizane ndi zofuna za chilango ndikupitirizabe kuwongolera. Pamene kuthamanga kwapamsewu kwakhala kovutirapo komanso luso lamakono, malonda asintha popanga njinga zawo kukhala zoyenera kutsika pamene akupitirizabe kukwera. .
Chitsanzo chabwino cha geometry yamakono yapamsewu ndi Specialized Epic, yomwe imafotokoza kuchuluka kwa zida zapamsewu zomwe zidasinthika.
Epic ndi yabwino kwambiri pazifukwa zothamanga kwambiri komanso zaukadaulo zamakono zakunja kwa msewu. Ili ndi ngodya yocheperako ya digirii 67.5, limodzi ndi 470mm wowolowa manja ndi nsonga (ish) 75.5-degree angle. poyenda ndi kutsika mofulumira.
2012's Epic ikuwoneka ngati yachikale poyerekeza ndi Baibulo lamakono.Nthawi ya 70.5-degree mutu chubu angle imapangitsa kuti njinga ikhale yozungulira, koma imapangitsanso kuti ikhale yosadalirika kutsika.
Kufikira kumakhalanso kwaufupi pa 438mm, ndipo ngodya yapampando imakhala yochepa pang'ono pa madigiri a 74. Mpando womasuka ungapangitse kuti zikhale zovuta kuti mupeze malo abwino oyendetsa pansi.
Momwemonso, yatsopano ndi njinga ina ya XC yomwe geometry yake yasintha.Nthawi ya chubu yamutu ndi madigiri 1.5 pang'onopang'ono kusiyana ndi chitsanzo chapitachi, pamene ngodya ya mpando ndi 1 digiri yowonjezereka.
Ndikoyenera kudziwa kuti tikujambula mizere yokhuthala pano.Kuphatikiza ndi ziwerengero za geometry zomwe tikuzitchula apa, pali ziwerengero zina zambiri ndi zinthu zomwe zimakhudza momwe njinga yamoto imagwirira ntchito, koma palibe kukana kuti XC geometry yamakono ili ndi zidachitika kuti njingazi zisamachite manyazi pokwera kutsika.
Tikukayikira kuti mukauza wokwera aliyense wa Olimpiki wa 2021 kuti athamangire parabara yocheperako, angakhumudwe kwambiri.
Pazaka khumi zapitazi, pakhala kuchulukirachulukira kwa matayala m'malo okwera njinga, kuyambira panjira kupita ku XC, ndipo matayala abwino kwambiri apanjinga zamapiri masiku ano ndi olimba kwambiri.
Nzeru zachikale zinkakhala kuti matayala ocheperako amathamanga mofulumira ndikukupulumutsani kulemera pang'ono. Zonsezi ndizofunikira pa mpikisano wothamanga, koma ngakhale matayala ocheperako amatha kukupulumutsani kulemera, matayala okulirapo amakhala bwino pafupifupi mwanjira ina iliyonse.
Amagudubuzika mofulumira, amapereka mphamvu zambiri, amapereka chitonthozo chochulukirapo, ndipo amatha kuchepetsa mwayi wa puncture.Zonse ndi zabwino kwa wothamanga wothamanga.
Palinso mkangano wina wokhudza tayala yomwe kwenikweni imakhala yothamanga kwambiri, ndipo sipangakhale yankho lomveka la funsoli.Koma pakadali pano, okwera ambiri akuwoneka kuti akusankha matayala a 2.3-inch kapena 2.4-inch pa mpikisano wa XC.
Tidayesanso zoyeserera zathu pakukula kwa matayala, kuyang'ana kukula kwa matayala othamanga kwambiri panjinga zamapiri komanso matayala othamanga kwambiri panjira.
Monga momwe wina ananenera mu kanema wokhudza akangaude, "ndi mphamvu zazikulu zimabwera ndi udindo waukulu" ndipo momwemonso ndi njinga zamakono zapamsewu.
Matayala anu okometsedwa, ma geometry ndi kukula kwa gudumu kumakupatsani mwayi woti mupite mwachangu kuposa kale.
Apanso, simuyenera kupita kutali kwambiri kuti muwone njinga yokhala ndi chogwirira chocheperako kuposa 700mm. Kuyang'ana kumbuyo, amayambanso kuviika pansi pa 600mm.
M'nthawi ino ya mipiringidzo yotakata, mwina mungadabwe kuti chifukwa chiyani wina angakwere m'lifupi mwake mopapatiza? Chabwino, liŵiro nthawi zambiri linali locheperako, ndipo kutsika kunali kocheperako.
Mwamwayi kwa tonsefe, pamene liwiro likukwera, momwemonso m'lifupi mwazitsulo zathu, ndipo njinga zambiri za XC zimakhala ndi 740mm kapena 760mm zogwirira ntchito zomwe sizikanatheka zaka khumi zapitazo.
Zofanana ndi matayala okulirapo, zogwirizira zokulirapo zakhala zachizoloŵezi kudutsa njinga yamapiri yamapiri. Iwo amakupatsani ulamuliro wochulukirapo pazigawo zamakono ndipo amatha kusintha momwe njingayo imayendera, ndipo okwera ena amaona kuti m'lifupi mwake kumathandizira kutsegula chifuwa kuti mupume. .
Kuyimitsidwa kwabwera modumphadumpha m'zaka khumi zapitazi.Kuyambira kutseka kwa magetsi kwa Fox mpaka kupepuka, kugwedezeka bwino, palibe kukayikira kuti njinga zamasiku ano zimakhala bwino kwambiri pamtunda wotsetsereka kapena waluso.
Kusintha uku kwaukadaulo woyimitsidwa, komanso kuti njirayo ndi yaukadaulo kwambiri kuposa kale, zikutanthauza kuti mutha kuwona njinga yoyimitsidwa kwathunthu kuposa hardtail pampikisano wapamwamba wa XC.
Hardtails ndi angwiro kwa maphunziro omwe tidawawona mumsewu zaka khumi kapena kuposerapo zapitazo.Tsopano zonse zasintha.Pamenepo ndi imodzi mwa maphunziro ochepa aukadaulo pamasewera apano a World Cup, ndipo imadzutsa funso ngati kusankha hardtail kapena njinga yoyimitsidwa yonse (Victor adapambana 2021 Men's Classic ndi hardtail, adapambana mpikisano wa Akazi kuyimitsidwa kwathunthu), okwera ambiri tsopano asankha mbali zonse ziwiri mumipikisano yambiri.
Osatilakwitse, palinso ma hardtails othamanga kwambiri ku XC - BMC yomwe idakhazikitsidwa chaka chatha ndi umboni wazovuta zapamsewu - koma njinga zoyimitsidwa tsopano zikulamulira kwambiri.
Kuyenda kukupitanso patsogolo.Tengani Scott Spark RC watsopano - njinga yomwe mungasankhe .Ili ndi 120mm yoyenda kutsogolo ndi kumbuyo, pamene takhala tizolowera kuwona 100mm.
Ndizinthu zina ziti zomwe taziwona muukadaulo woyimitsa? Tengani Kuyimitsidwa kwaubongo kovomerezeka kwa Specialized, mwachitsanzo.Mapangidwewa amagwira ntchito pogwiritsa ntchito valavu ya inertia, yomwe imatsekereza kuyimitsidwa kwa inu pamalo athyathyathya. M'malo mwake, ndi lingaliro lanzeru, koma pochita, kubwereza koyambirira kwapatsa ubongo otsatira ena adziko lapansi.
Chidandaulo chachikulu chinali kugunda kwakukulu kapena kugunda kwa wokwerayo anamva pamene valavu inatsegula kachiwiri.Simungathenso kusintha kukhudzidwa kwa ubongo wanu pa ntchentche, zomwe sizili zabwino ngati mukukwera pa malo osiyanasiyana.
Komabe, monga zonse zomwe zili pamndandandawu, Specialized yasintha ubongo pang'onopang'ono m'zaka zapitazi. Itha kusinthidwa pa ntchentche, ndipo phokoso la percussive, likadalipo, ndilofewa kwambiri kuposa mibadwo yam'mbuyo.
Pamapeto pake, kusinthika kwa kugwedezeka ndi chitsanzo chabwino cha momwe njinga za XC zamasiku ano zimapangidwira kuti zikhale zokhoza komanso zosunthika kuposa kale lonse.
wakhala akupikisana muzochitika zosiyanasiyana zosiyanasiyana kwa zaka khumi, kuphatikizapo kudutsa, marathon ndi kukwera mapiri, ndipo tsopano akusangalala ndi moyo wokhazikika, kuyima m'malesitilanti ndi kumwa mowa atakwera njinga. nthawi, amasangalalabe kukwera phiri ndi kuzunzika pa kukwera.Monga wothandizira mwamphamvu wa mapiri olimba okwera njinga pamsewu, mungapezenso kukwera wokondedwa wake pamene dzuwa likulowa.
Polemba zambiri, mukuvomereza Migwirizano ndi Zikhalidwe za BikeRadar ndi Mfundo Zazinsinsi.Mutha kudziletsa nthawi iliyonse.
