Ngaba iibhayisekile zeMagnesium zilungile?

Magnesiuminokusetyenziselwa injineliibhayisekileizakhelo ezikhaphukhaphu kune-aluminiyamu ngelixa zigcina amandla aphezulu okuqina kunye nokuthothisa amandla. Konke oko kukhokelela kuhambo olugudileyo nolusebenzayo.Magnesiumiza ngexabiso elisezantsi kunezinto ezithandwayo ezinobunzima obufana nekhabhoni ifayibha.Agasti 8 Ngo-2018





(umculo omnandi) (umculo omnandi) (umculo omnandi) Emva kokugubungela i-carbon fiber, i-aluminium, intsimbi kunye ne-titanium, bendicinga ukuba siyigqibile ikhosi yesayensi yezixhobo ze-GCN, kodwa hayi! IMagnesium ngoku ikwikharityhulam enkosi kwinkampani ebizwa ngokuba yiAllite. I-Magnesium sesona sinyithi sigqwesileyo kwindalo iphela ngokobunzima. Yeyona yesine ininzi kakhulu kwiplanethi yoMhlaba kwaye, enyanisweni, ingummangaliso we-13% yobunzima bomhlaba ngokwenene yi-magnesium.

Ikwayintsimbi yesithathu esetyenziswa kakhulu kwisakhiwo, kutheni ke iibhayisikile ezimbalwa okanye iibhayisekile zenziwe ngale nto? Ewe, kweli nqaku ndiza kukuxelela kwaye ndiza kukuxelela nendlela i-Allite eyinkampani yesayensi yezixhobo ezifuna ukuyitshintsha ngayo ngemagniziyam entsha. Benza iintlobo ngeentlobo zemagniziyam alloys kusetyenziso olwahluka-hlukeneyo, kumatshini, ekwakhiweni nakwimizi-mveliso yezithuthuthu ngoku. Inkampani yabo engudade VAAST yeyokuqala ukumilisela enye apha kwaye uyokwaneliseka.

Ngokungafaniyo neetekhnoloji ezininzi ezintsha, le ayinalo ixabiso leprimiyamu. (umculo omnandi) Nangona kwakungekho nyani iibhayisikile zemagniziyam kwimveliso ukuza kuthi ga ngoku, bekungasoloko kunjalo. Ngapha koko, kuye kwakho amabhayisekile amahle eMagnesium kule minyaka idlulileyo.



I-Kirk Precision, eyayijongwa nguJohn kwiiveki ezimbalwa ezidlulileyo, kunye nePinarello Dogmas ukusukela phakathi ku-2000s nayo yenziwe ngemagniziyam. Omnye wabo waphumelela iTour de France ngo-2006 phantsi kuka-Oscar Pereiro ukuba i-magnesium ayizange ibambeke njengesixhobo sesakhelo, olunye loloyiko lokuba endaweni yokuyibamba, inokutsha nje. Ewe, masijongane nendlovu egumbini kuqala, akunjalo? Andikhumbuli kakhulu kwiintsuku zam chemistry esikolweni, kodwa ndiyakhumbula ngokucacileyo ukubeka i-magnesium emlilweni, ewe.

Kodwa awunakukhathazeka ukuba i-steed yakho entsha inokutshisa ngokuzenzekelayo kuba into onokuyikhumbula kwisikolo esiphakamileyo yimagnesium powder okanye iiribhoni zemagniziyam, ekulula ukuzitshisa kwaye zitshise ngokumangalisayo. Kwizixa ezikhulu, i-magnesium kunzima kakhulu ukuyitshisa kwaye enyanisweni le alloy, i-AE 81, iyanyibilika xa ifikelela kumaqondo obushushu angaphezulu kwe-600 ° C endaweni yokubamba umlilo njengayo nayiphi na enye intsimbi. Ndiza kuthembeka ngokupheleleyo, andikhathali, kuba andikuthandi ukuqhuba kubushushu obunje.

Inyaniso yokuba i-magnesium ayitshisi ngokulula ayisi kuchazi ukuba kutheni isisinyithi sesithathu esona sithandwayo, kodwa ubukhulu bayo iMagnesium ilula ngokwenene. I-75% ingaphantsi kwentsimbi kunye nokukhanya Isakhelo senza i-33% ibe ngaphantsi kwe-aluminium njengomzekelo: inobunzima nje obuyi-1190 yeegram, ehambelana ngokulinganayo kwisakhelo sekhabhoni yefayibha efanayo, enye efanayo sisakhelo esithile seGravel le kwaye ayisiyiyo ingqikelelo yobunzima basentwasahlobo, le yenzelwe ngohlobo lokuba isebenziseke kakhulu xa ithelekiswa nezinye izinto ezifana ne-rack kunye ne-mudguard hanger kunye nemithwalo yemithwalo, kwaye i-VAAST ithi yomelele kakhulu.



Batsho ukuba bafuna isakhelo esinye sokusinda kuzo zontathu iimvavanyo ezisemgangathweni zamazwe aphesheya kwaye basokola kwelinye icala, kwaye bagxininise isakhelo esinye kuba eneneni akukho mithetho inqanda umenzi ekwenzeni into entsha kraca kuyo yonke into entsha vavanyo Ngenisa isakhelo. Yeyiphi, ukuba uyandibuza, ibonakala ngathi ityhafile kancinci. Ewe, okokuqala, ukongeza kwi-aluminium, kukho izinto ze-alloy ngokwazo, ezomeleza kwaye zenze lukhuni umbandela.

Kukho ipesenti yezinto ezinqabileyo zomhlaba, ngokuchasene negama, eneneni azinqabile. Zizo, h Nangona kunjalo, zisasazeke kakuhle kwaye azifane zifumaneke kwifomeral mineral kwaye, ngendlela, chaza igama le-alloy. Ke u-A umele ialuminium, u-E umele umhlaba onqabileyo kunye namanani emva kokuma ngokobungakanani bawo, ngoko ke i-8% yealuminiyam, 1% inqabile yomhlaba kwaye inyani lesibini kungenxa yobungakanani beekristal kule alloy, ukuze incinci Amakristali enza isinyithi esomeleleyo kwaye kule meko u-Allite eneneni unenkqubo yokupholisa ikristallisisi enelungelo elilodwa lomenzi nto leyo ethetha ukuba iikristali kule alloy zingama-20% zincinci kune-magnesium eqhelekileyo, oko kuthetha ukuba isinyithi somelele njengesiphumo.

Nangona kunjalo, i-modulus yelastiki yezinto ibonisa ukuba le magnesium ephezulu isesincinci kancinci kune-aluminium, kodwa njenge-aluminium incinci kuneyentsimbi, unokukuhlawulela oku ngemibhobho emikhulu enobubanzi kwaye ngezinto kukuba ukuba unqwenela ukujija kancinci, kusathetha ukuba unokwenza ityhubhu eqinileyo yegrama. Njengoko benditshilo ekuqaleni, iivili zemagniziyam bezikade zikho ngaphambili, kodwa hayi ixesha elide kwaye ngamanye amaxesha ziyinyani, kwaye kungenxa yokuba enye yeengxaki zembali enamavili emagniziyam iye yaba kukudamba. Ke yenza ntoni i-VAAST ukuqinisekisa ukuba oku akwenzeki kwibhayisikile yabo entsha yegrabile? Okokuqala, inxenye ixhomekeke kwizinto ngokwazo, okokuqala, kufuneka unciphise inqanaba lokungcola kuyo, njengoko ubukho bezinto ezinje ngobhedu kunye nentsimbi zonyusa utyekelo lokonakalisa iMagnesium inyuke kakhulu, kwaye okwesibini, ukubandakanywa kwezi zinto zinqabileyo zomhlaba kule alloy ethile iya kuphucula ukumelana nokubola kwaye xa udibanisa ezimbini kwi-Super Magnesium zibonakala ngathi zihamba ne-aluminium ngokwendlela yabo yokonakalisa.



Ke into yesibini kukuba izakhelo zinikwe i-VAAST yokutyabeka kwiplasma electrolyte oxidation ukuze isakhelo sibhaptizwe kwindawo yokuhlamba ekhethekileyo kwaye sishiye isambatho sodongwe ngaphezulu kwesakhelo ngaphakathi nangaphandle kwemibhobho, kuyacaca ukuba le yinto ukutyabeka okunzima. Ngaphandle kwepropati yolwakhiwo lwesinyithi umzuzu, kum ifuthe lokusingqongileyo kwesi sixhobo yenye yezinto ezomeleleyo kwaye akuthethwa ngalo rhoqo kwiibhayisikile. Kodwa okunene iimveliso ezininzi esizisebenzisayo zintle kakhulu kwindalo esingqongileyo.

Thatha i-carbon fiber, umzekelo, enexabiso eliphezulu kakhulu lokusingqongileyo ukuvelisa, kwaye, enyanisweni, akunakwenzeka ukuba iphinde iphinde isetyenziswe ngendlela enentsingiselo. Nangona kunjalo, oku kufuna i-40% yamandla amancinci ekwenziweni kune-aluminium kwaye inokuphinda iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphelile. (Umculo wenyuselo) (umculo oqhubela phambili) Ndiyazi ukuba abantu bahlala befuna ukubonisa iimpawu ezithile zokuqhuba kwizinto ezithile zesakhelo.

Ke umzekelo uhlala uhlala usiva ukuba intsimbi ichazwa njengephendulayo kodwa exolelayo, kwaye i-titanium inentwasahlobo kwaye iyaphila, kwaye ialuminiyam ibisoloko ixelelwa ukuba ilukhuni, kodwa ngoku ngeendlela zangoku zemveliso inokuhlala kamnandi kwaye iqine, kunye nekhabhoni ifayibha, Kulungile, ewe, kunokuba nzima, konke kunganikezela, ke, uyathemba ukuba andiyixhasi le ndlela yokucinga ijuba, ndicinga ukuba iteknoloji yebhayisekile ibaluleke kakhulu, ukuba ayibalulekanga ngaphezu kwezinto ngokwazo, kodwa nam ndiyaqikelela ukuba mhlawumbi uyandithanda Zama ukucacisa ukuba imagniziyam injani. Ndikude nekhaya kwaye nditshintshele umlenze ngaphezulu kwayo kwaye andizukuhlala ixesha elide kuloo bhayisekile. Ndiza kuzama ukukunika umbono wam wokuqala ukuba unqabile ngokupheleleyo into elungileyo, ibarbar yokuphatha ivakalelwa ngokungathi ixhunyiwe kumatshini ofanayo nesali kwaye uphuma esihlalweni kwaye uphendula kakhulu, kodwa nayo ndiziva ngathi ityibilika kakhulu kolu hlobo lokungcangcazela okuphezulu njengokungcangcazela kuncitshisiwe kwaye kusenokwenzeka ukuba ndisebenzisa iivili zentsimbi kwaye ezi zihlala zisetyenziselwa ukuqina iivili zekhabhoni okanye ndine-38c -Tire enkulu, kodwa inokuba izinto ezikwisakhelo ngokwaso, ndiyaqikelela, kodwa olo luluvo lwam lokuqala.

Ndithe ekuqaleni kwenqaku ukuba obu buchwephesha butsha abufumaneki ngexabiso leprimiyamu, kwaye umzekelo le bhayisekile yegrabile ye-VAAST A1 ene-Shimano evela kwiqela le-GRX iyakuthengisa malunga ne-2,500. ithengisa iidola. Ngoku kukho uluhlu olukhulu lweebhayisekile zegrabile onokuzithelekisa, kodwa kwibhokhwe yam ndingathi mhlawumbi yinto encinci kunebhayisekile enokuthelekiswa nesakhelo sekhabhoni, kwaye oko kuthetha ukuba kungaphantsi kwebhayisekile enobunzima obulinganayo.

Into endicinga ukuba iyonwabisa. Njengoko ubona sinamavili e-Stans 700c apha, nangona kukho ukhetho lwe-650b apho unesangqa esincinci sangqa. Khumbula apho ulingana khona namatayara abanzi ngokufanelekileyo.

Ndinokuqhelisela ikhabhrikhi apha, enomdla kakhulu kwisakhelo nge-T47 isibiyeli esisezantsi, apho ufumana khona iqokobhe lesibhontsi esisezantsi, kodwa sinobubanzi obukhulu ukuze ulingane i-crmm yokujija eyi-30mm apho ngokuchanekileyo iibheringi, ibakaki entsha esezantsi esemgangathweni okanye entsha, kodwa ngokuqinisekileyo inye kufuneka sonke sonwabe ngayo. Masambe ke, kukho ibhayisekile yakho yegrabile ye-VAAST A1 eyenziwe nge-AlliteAE 81 Super Magnesium. Thatha inxaxheba kwicandelo lokuphawula kwaye usazise ukuba ucinga ntoni ngemagniziyam.

Ngaba yinto entsha ngokuhambelana nezinto zesakhelo sebhayisekile? Ndingathanda kakhulu ukuva iingcinga zakho. Ukuba ufuna ukufumana ezinye zezi ziqendu zangaphambili zekhosi yeSayensi ye-GCN, nceda ucofe isikrini ngoku ukuze ubhekiswe kwiTitan.

Ngaba uRaleigh luphawu lwebhayisikile olulungileyo?

Ke, ukuphendula umbuzo wakho,URaleighKunjeKulungileumgangatho njengayo nayiphi naibhayisekileibanga levenkileibhayisekilengexabiso elifanayo. Ukuba uthelekisaURaleighngomgangatho ophezuluIimpawuezinje ngeTrek okanye i-Specialised okanye iCannondale uyakufumanisa ngokubanziURaleighiya kuba nayongconoizinto ngexabiso elifanayo okanye izinto ezifanayo ngexabiso eliphantsi.

Yeyiphi ibhayisekile elungileyo yokungena kwinqanaba? Ndifumana lo mbuzo yonke imihla. Kungenxa yoko le nto namhlanje ndikunika izixhobo ozifunayo ukuze ufumane ibhayisekile entsha okanye esele uyisebenzisile ngaphandle kophawu. Kodwa kuqala kufuneka sichaze ukuba yintoni ibhayisekile ekungenwa kuyo.

Ukuba usaqala kwaye unemali engasikelwanga mda le ngxoxo iphelile. Mane uphume uye kuchitha isipha semali kwibhayisikile entle kwaye ugqibile. Kodwa ndicinga ukuba uninzi lwabaqalayo bafuna ukuzibophelela okuncinci kwezemali abanokuthi bakwenze ngelixa befumana ibhayisekile efanelekileyo yentaba.

Le bhayisekile inesidima ngokwaneleyo ukuba ikufake engxakini enkulu amaxesha ngamaxesha. Okungcono okwangoku, iyafumaneka nge-329 yeedola. Ewe yiDiamondback Overdrive kwaye ndikhwela iDiamondback, kodwa ndifuna ukuba ulibale namhlanje kuba iDaybackback isenokungafumaneki apho uhlala khona okanye ujonge ibhayisekile esele isetyenzisiwe.

Namhlanje ndifuna ukuba wenze ngathi le bhayisekile ayinambala kwaye ayinazimpawu. Singaqiniseka njani ukuba 'iyalandeleka' ukuba uyayivavanya? Masiqale ngesona salathisi sibaluleke kakhulu sebhayisekile yentaba elungileyo: isibeki sedreyile. Ukuba ibhayisikile yasezintabeni ixhotywe ngesisixhobo esingasemva, kufuneka ixhonywe kwisakhelo sesi siqwenga sentsimbi sibizwa ngokuba yihanger.

Kwimeko yokuwa, ihanger yenzelwe ukwahlula ukuthintela ukonakala kwesakhelo. Inokuphinda ibonwe kwakhona okanye ibuyiselwe ngexabiso eliphantsi. Oku kubhetele ngakumbi kunokuphosa ibhayisekile yonke emgqomeni, yiyo loo nto kufuneka uyenze ukuba wophule naliphi na icandelo lesakhelo sakho.

Lumka ngezixazululo zepatch, okanye okubi ngakumbi, nge-derailleur efakwe ngqo kwisakhelo. Iibhayisikile ezinje ngezi kunokuba kukuwa nje kwintshabalalo epheleleyo, kwaye ukuhamba ngeebhayisikile ezintabeni konke malunga nokuwa. Ke ngoko, isikhuseli sedreyini yeyona nto yokuqala ekufuneka uyenzile.

Qinisekisa ukuba ibhayisekile ilungile. Nokuba iibhayisekile zilula kakhulu zisikwe ngokuchanekileyo, zisebenza ngokubonakala kwendawo yedreyini. Ke uphando lwakho kufuneka luqale kwaye mhlawumbi luphele ngalo.

Inxalenye elandelayo ebalulekileyo ekufuneka uyijongile yimisonto ye-SS enomsonto, onokuyichonga ngezi bholiti zecompamp apha, kwaye ezi zine iibholiti ezibambe indawo yokubamba. Ukuba ubona oku endaweni yoko, zihlala ziziindaba ezimbi. Ukuba unento oyisebenzisayo okanye oyibuyisela ngaphambili, kubandakanya ifolokhwe, ukhawulelwe kwiindawo ezingathembekanga okanye kwiindawo zebhayisekile zeentaba ekunzima ukuzifumana.

Ngethamsanqa ukulandelela into entsha kraca yama-90s yokumisa ifolokhwe yokutshintsha eyakho endala. Ayisiyisiqu nje kuphela esingenomsonto esilula kwaye sitshiphu ukusigcina, kodwa siqinile, into oya kufuna ukuyicekisa kuyo. Xa ufika kumavili, kufuneka uqiniseke ukuba anezinto ezikhawulezayo zokukhulula.

Ezi zixhaphakile kwinqanaba lokuhamba ngeebhayisekile kwaye zikuvumela ukuba ususe okanye ubeke endaweni yazo iivili ngesandla ngaphandle kwezixhobo, kodwa okona kubaluleke kakhulu, zizalathiso zokusetyenziswa kwebhayisekile. Ukuba amavili acabaleleyo awunakuphepheka xa uhamba ngebhayisikile entabeni, kuyingxaki ukusoloko unesitshixo se-15mm kunye nawe ukususa la mantongomane. Okubi nangakumbi kukuba iibhayisekile ezisezintabeni ezinamantongomane kwiiasi asi phantse zingenakwenzeka ukuba ziphucule amavili, kwaye amavili yenye yezinto oza kuphuma njengoko ufumana amava.

Ke kwibhayisekile yokungena kwinqanaba, jonga ukukhululwa okukhawulezayo kwaye ukuba ubona amandongomane, hlala kude. Okulandelayo kuza i-crank kunye nokudityaniswa kwendibano yemodyuli kwaye kudityaniswe kunye, kungabanjiswanga kunye njengesiqwengana esikhulu. Ndiqinisekile ukuba uyayibona ingxaki koku.

Yaphula into apha kwaye mhlawumbi lixabiso lebhayisekile yakho yonke ukuyila into, ke ukuba yinto yakho leyo kulungile kuwe. Ngaphandle koko jonga into onokuthi ujije kuyo. Into elandelayo ekufuneka uyijongile ziibreyiki zangaphambili nezingasemva.

Nokuba iziqhoboshi zexabiso eliphantsi zinokutshintshelwa kwezingcono, kubalulekile ukuba uqaphele kuba ibhayisekile yakho kufuneka ibe neendawo zokuncamathisela kweli lungelo kwasekuqaleni. Okubaluleke ngakumbi, iibhuleki zeediski zithembeke ngakumbi kuneebreyikhi zerim, yiyo loo nto ishishini lebhayisekile lentaba likhawuleze latshintshela kubo kumashumi eminyaka eyadlulayo. Ngenxa yokuba ibhayisekile elungileyo yasezintabeni kufuneka ingalondolozwa kakhulu kwaye inyuselweke, umntu kufuneka akrokre kakhulu ngaphandle kwe-disc brakes.

Okokugqibela, kuya kufuneka uqiniseke ukuba ibhayisekile iza ngobukhulu obahlukeneyo kwaye umvelisi ubonelela ngesikhokelo kubungakanani obufunayo. Oku kulula njengokusebenzisa uGoogle, ubugcisa obulahlekileyo. Ngayiphi na imeko, ukuba umenzi akaluniki olu lwazi, ngekhe bacinge kakhulu malunga neebhayisikile zabo kwaye ke akufuneki ubathembe bakuse nzulu ehlathini, ke esi salathisi asinanjongo kunezinye , kodwa ubuncinci kufuneka ufumane enye ibhayisekile ekufaneleyo.

Ngelixa ezinye izikhombisi zebhayisekile zilungile, azisebenzi kakhulu ukuba ibhayisekile ekuthethwa ngayo ayihlangabezani neemfuno esiza kugxila kuzo kwinto esinokuyilindela kwibhayisekile ekwinqanaba lokungena ngolu hlobo kunye nezinye zezinto onokuyenza ngayo ungenza ukuyiphucula. Okokuqala, kubalulekile ukuba uqaphele ukuba phantse zonke iibhayisekile zenqanaba lokungena zii-hardtails okanye iibhayisikile ngaphandle kokumiswa ngasemva.

Unxibelelwano olufunekayo lokumiswa ngasemva luyabiza kwaye lunzima, ke ngoku akufanelekanga ukuba utyale imali de uqale ukophula inqaku ledola eliwaka. Ngenxa yokulula, siza kunciphisa le ngxoxo kwii-hardtails. Ii-Hardtails ziyonwabisa kwaye ziyakhawuleza, ke zilungile ukuba ungaqala ngazo.

Kodwa ii-hardtails eziphantsi kwe- $ 500 ziphantse zihlala ziyi-XC okanye ii-bikes ezinqamlezayo. Iibhayisikili ze-XC zilungiselelwe ukuhambisa kunye nokuhambisa umbane. Ziyakhawuleza kwaye kulula ukuzisebenzisa xa uhamba imigama emide.

Kodwa ezi zibonelelo zinokukubamba umva xa uqala ukuzama isandla sakho kwi-freeriding. Oko akutsho ukuba awukwazi ukutsiba kancinci kwibhayisikile yeXC. Ukutsiba nje, ukuhla, ukuqengqa amatye okanye naluphi na uhlobo lokuhla okude kwenziwa ngcono kwibhayisekile yomzila.

Le hardtail emnyama ecaleni kweOverdrive ngumzekelo olungileyo webhayisekile yendlela. Ifolokhwe erakiweyo, ii-angles ezinobundlobongela, izibambo ezibanzi, ukuhamba ixesha elide, kunye nesiqu esifutshane kwenza ukuba kube ngcono kuhlobo lokukhwela endikwenzayo. Kuba awukwazi ukuguqula ibhayisekile yeXC ibe yibhayisikile yeTra il okanye enye into, kuya kufuneka uthembeke malunga nento ofuna ukuyenza ngebhayisikile yakho yentaba ngaphambi kokuyithenga.

Kodwa ukuba uhlahlo-lwabiwo mali luphantsi kwe- $ 500, nokuba uyayithanda okanye awuyithandi, ungafumana ibhayisekile ye-XC. Ukuba ngaxesha lithile uqhubela phambili ngokutsiba kwaye uphosa ibhayisekile ngaphezulu kancinci, unokuziva unyanzelekile. Nantsi into endiyenzileyo ukuphucula ukubanakho kohlahlo-lwabiwo mali lwe-XC.

Eyona nto unokuyenza, izandla phantsi, ukutshintsha amavili. Xa ndawaphosa loo matayara abanzi, atshixwayo kwindawo endandihamba kuyo, kwavakala ngathi yibhayisekile eyahluke mpela. Ndikwazile ukuwaqhuba la matayala uxinzelelo olusezantsi, olwenza ukuba lubambeke ngakumbi kwaye lixolele.

Kodwa akuphelelanga apho. Ngaba uyeva konke ukungxola kwetyathanga lam eliqhwatyelwe izandla kuyo yonke le ndawo, kwaye ngenene laphuma laya kumathontsi aliqela kunye nokutsiba. Ukulungisa le nto, ndifake isikhokelo setyathanga esisuse ingxaki.

Oku kuyakubiza imali encinci kunokuhlaziya i-drivetrain yakho, enokukuqhuba ngokulula njengale bhayisekile. Ukuba bendingumqali wokufika kangangoko kule bhayisekile ndingaphinda ndinyuse i-pedals kwaye mhlawumbi imfoloko iye kwinto enjalo, ithengise ngcono kwaye uyihlaziye yonke loo nto. Emva kwayo yonke loo nto, ukuba sele unayo ibhayisekile kwaye ufumanisa ukuba iyasilela kwezinye zezi mvavanyo, usengazuza kweli nqaku.

Ukuba ngoku iyakusebenzela kwaye uyayonwabela, ke qhubeka uhlamba. Ukuba uziva ngathi ikubambile, ngoku unezixhobo zokufumana into ebhetele. Oko kwathethileyo, khange sithethe ngendibano, ulondolozo, okanye zonke ezinye izinto onokuziphucula ngoncedo lwababukeli bam, ndiza kwenza konke okusemandleni ukubaphendula kwizimvo.

Ke fumana ibhayisekile elungileyo yabaqalayo uyonwabele. Kungenxa yokuba unonyaka nje kuphela ungathengisi yonke into onayo kwaye uxhase ngemali ibhayisekile yezemali ebiza ngokungenankathalo. Kwenzeka kweyona nto intle kuthi.Siyabulela ngokundisusa namhlanje kwaye sizokubona kwixa elizayo.

Ngaba iibhayisekile ze-bottecchia zilungile?

Inkqubo ye-IibhotileIDoppia T2 yibhayisekile elungelelaniswe kakuhle kunye noyilo olubalaseleyo kunye nephakheji yemizobo. Inkqubo ye-IibhotileI-Doppia T2 yayingenanto ngaphandle kokuphononongwa ngokutsha kweqela leSoCalCycling.com.

I-Itali yaziwa ngokuba nomnqweno wokuhamba ngebhayisikile, ilifa layo elityebileyo elinokuthi ngokuqinisekileyo likhaya lokomoya lezemidlalo sonke esilithandayo. Ngoku, ecaleni kweyona ndlela imangalisayo, ukutya okumnandi kakhulu, kunye neentsomi ezinkulu zokuhamba ngebhayisikile, i-Itali ivelise ezinye zeebhayisikile eziphambili ezakha zakhwela, kwaye nazi ezinye zeempawu eziphambili zebhayisikile zase-Itali. IBianchi yeyona nkampani indala yeebhayisekile ehlabathini isekushishino namhlanje kwaye yasekwa ngu-Edoardo Bianchiway ngo-1885.

Ukongeza kwisithethe sayo esityebileyo, iibhayisekile zeBianchi ziyafana ngombala omnye kunaye nawuphi na umenzi webhayisekile: uCeleste, umbala oluthuthu oluthuthu. IBianchi ixhase umkhweli wayo wokuqala wobuchwephesha, uGiavanni Tomasello, ngo-1899, kwaye kwiminyaka eli-15 kamva inkampani yavelisa iibhayisikile ezingama-45,000 ngonyaka kunye nezithuthuthu ezili-1,500 neemoto eziliwaka. Kwaye babethengisa amabhayisekile angama-70,000 ngonyaka ngo-1935, xa iibhayisekile zaseBianchi zazingabokuqala ukusebenzisa inkqubo entsha kaCampagnolo, inkqubo yokutshintshela ngentonga ebizwa ngokuba yiCambio Coursa, ene-derailleur yangasemva eyatshintshela ikhonkco kwiziporo ezine ezikhoyo, ngo-1939 unyaka uGiuseppe Olmo naye waseta irekhodi elitsha leyure ebhodini ye-Bianchi.

Impumelelo yaqhubeka xa uFausto Coppi wajoyina iqela laseBianchi ngo-1940. Kwaye ngo-1949, i'Champion of Champions ', njengoko wayesaziwa njalo, waba ngumkhweli wokuqala owaphumelela iGiro d'Italia kunye neTour de France kwangalo nyaka. , owamisa isamente kunye negama likaBianchi kwiincwadi zonyaka zembali yebhayisikile, ecaleni kweCoppi Bianchi nezinye ii-greats zokuhamba ngebhayisikile ezinje ngoFelice Gimondi, uLaurent Fignon, uGianni Bugno noMarco Pantani, abakhwele i-aluminium yakhe eyenziwe nge-Mega Pro XL Reparto Corseto ukunika Igama lakhe elipheleleyo kwi-Giro d'Italia / Tour de France edumileyo ngo-1998, umkhweli wokugqibela ukufezekisa le Herculean feat kunye nomkhweli wokugqibela ukuphumelela iTour de France kwisakhelo sealuminium. Ngoku uPantani wayethe phithi yijiyometri yebhayisikile yakhe kwaye wakhwela izakhelo ezingama-30 ezahlukeneyo ngexesha elinye, nganye nganye yahlukile kancinci.

UCeleste oqhankqalazayo usabonwa kuluhlu namhlanje, eqhutywa liqela leDatshi leLotto NL-Jumbo laseDatshi, abaneendlela ezintathu ezahlukeneyo abanokukhetha kuzo, kwiimodeli zika-Oltre, Specialissima kunye ne-Infinito. Ngoku usenokuzibuza ukuba ivela phi iBianchi crest, uEdoardo Bian chi wafundisa uKumkanikazi uMargherita ukukhwela ibhayisekile kwaye kwiingxaki zakhe wafumana ingqesho yasebukhosini okanye itywina elamvumela ukuba abe neBianchi crest kuwo wonke umntu Indawo yesakhelo. (umculo omnandi wase-Italiya) IColnago yasekwa e1952 eCambiago, e-Italiya ngu-Ernesto. yasekwa iColnago kwaye yakha ngokukhawuleza igama lokuba yenye yezona ndlela zilungileyo zokuvelisa isakhelo sendlela emhlabeni.

U-Luigi Ariento uphumelele imbasa yegolide kwimidlalo ye-Olimpiki yowe-1960 kugqatso lweColnago. U-Ernesto akapheleli nje ekubalekeni inkampani kodwa wayeyi-mechanic eyintloko yeqela lase-Molteni kwaye uloyiso luka-Michele Dancelli e-Milan San Remos 1970 lukhuthaze i-Asso di Fiori okanye i-logo ye-Ace yeeKlabhu. Ngo-1971 uEddie Merckx othile wajoyina iqela laseMolteni kwaye wasebenza ngokusondeleyo noErnestoon ukuphuhlisa izithuthuthu awayezihamba, zaze zafikelela kwisinyithi esikhanyayo esenziwe ngo-1972 esophula irekhodi leyure yehlabathi.

Le mpumelelo ikhokelele inkampani ukuba ingene kwimarike yebhayisikile yokuvelisa, ixhotyiswe yibhayisekile yeebhayisikile kwii-1970s zokuqala, ngelixa u-ch wabona ukwaziswa kweemodeli eziphambili zeSuper neMexico ngembeko yerekhodi leyure. Baye baqhubeka nokwenza ubuchule kunye nokuzama iindlela zokonyusa ukuqina kwesakhelo ngokusebenzisa i-oval kunye ne-crimped tubular frame kunye neColumbus tubing, ekhokelele kwi-Master Range edumileyo, uGiuseppi Saronne waphumelela i-Pro World Road Race ngo-1982 ngesakhelo esinjalo. Ngexesha lama-80s nama-90s, uColnago uqhubekile nokuphonononga ukwakhiwa kunye nokuyilwa kwesakhelo, ngokuqaliswa kwesakhelo sokuqala sekhabhoni yentsimbi ngo-1994, i-C40, eyakhiwe ngetyhubhu yekhabhoni enee-lugs zensimbi engasindi.

I-C40 yabetha kwangoko, ichasa ulindelo lwentsebenzo kwaye yaphumelela iParis-Roubaix amatyeli amahlanu ukusuka ngo-1995 ukuya ku-2000 nabaqhubi bakaMapei uJohan Museeuw, uFranco Ballerini no-Andrea Tafi. Iinguqulelo ezininzi zesakhelo sekhabhoni zilandelwe, nganye nganye iphakamisa ibha ngokugqwesa, izithuthuthu zazifunwa kakhulu. Ngo-2014, basebenze noFerrari kwi-V1R aerobike, okwesihlandlo sesibini bebesebenza ngebhodi yezemidlalo yokunethezeka nasemva kokusebenza kwitekhnoloji ye-carbon fiber kwii-1980s.

Izithuthuthu zabo ziya kuqhubeka nokukhweliswa kwelona nqanaba liphezulu, neqela le-UAE Emirates ngoku lisebenzisa i-C60 kunye neConcept aero izakhelo ezinee-greats ezinje ngoAlexander Kristoff, uDan Martin kunye noFabio Aru (uMculo) uPinarello yasekwa ngo-1953 nguGiovanni Pinarello owayesakuba yingcali, oqale ngendibano encinci kwaye wakha iibhayisekile eTreviso. Ngo-1961, uCicli Pinarello, njengoko wayebizwa njalo ngelo xesha, waxhasa umqhubi wabo wokuqala, uGuido de Rosso, owaphumelela lo nyaka weTour de l'Aveniron owenziwe ngentsimbi esisiqholo kunye neblue Pinarello. Ngo-1975 uPinarello waphumelela iGiro d'Italia yakhe yokuqala, noFausto Bertoglio owayekhwele imodeli ekhethekileyo yentsimbi enetyhubhu kaColumbus.

Kwaye kwiminyaka eli-13 kamva, ngo-1988, benza imbali xa umSpanish Pedro Delgado wabamba uloyiso lokuqala lwe-13 iTour de France, nangona wayekhwele ezintabeni kwi-TVT92 ene-aluminium kunye neetyhubhu zekhabhoni, ezazibizwa ngokuba yiTreviso . Ngeminyaka yoo-1980, uphawu lwalujolise kwisakhelo se-ello SLX saseMont esathi, ngoncedo lomkhweli wase-US u-Alexi Grewal, waphumelela igolide kwimidlalo ye-Olimpiki ka-1984 eLos Angeles. Ngelixa ezinye iimodeli ezithandwayo ngelo xesha yayiziimodeli zonke zentsimbi uTreviso noGavia baphinde bahlola umhlaba woomatshini bokuzama ixesha, bezama ngemibhobho egobile kunye noyilo loyilo, kwaye ngo-1988 basungula umatshini wabo wokuqala ophantsi kunye noPrologo owahlukileyo.

Ukufika kukaMiguel Indurain kwinqanaba lehlabathi ngo-1991 kwathatha uPinarello waya kwiindawo eziphakamileyo, iSpanish yaphumelela izihlandlo ezintlanu ezilandelelanayo iTour de Franceson uthotho lweepinarellos, ngo-1994 yaba ngunyaka wokugqibela ukhenketho lwaphunyezwa ngesithuthuthu sentsimbi. Ngo-1995, i-Indurain yaqhuba isakhelo se-aluminium Keral Lite siphumelela okokugqibela, kunye no-Bjarne Riis ethatha u-win '96 edition kwisakhelo esinye, ngexa u-Jan Ulrich ebenomnqa ophumeleleyo ophumelele ii-brand ezisixhenxe ngokuthe kratya ngokuphumelela i-Pinarello ka-1997. I-Paris kwi-aluminium eyenziwe nge-TIG eyenziwe nge-welding kunye ne-Columbus tubing TT yoyilo lwesakhelo yaqhubeka ukuya kwiminyaka ye-1990 kwaye yavelisa iziqhamo, incediswa yi-Indurain's unearthly physiology, ngokutyhilwa kwebhayisekile yokuqala ye-carbon TT, i-Espada, ngo-1994, xa i-Indurain uqhekeze irekhodi leyure lehlabathi kwaye wavavanya ingxelo yesitalato, wachitha ixesha lokulingwa. I-millennium entsha ibhengeze isizukulwane esitsha seefreyim ezininzi zekhabhoni kunye neNkosana, kwaye kutshanje kuthotho lweDogma apho uBradley Wiggins waphumelela khona iTour de France ka-2012.

Baphumelele kane eTour de France ngoncedo lukaChris Froome Ukusukela ngoko, eyokugqibela yalandelwa ngo-2017 kwiflegi entsha ye-F10. (Umculo wase-Italiya we-acoustic) Uphawu oluyinyani, kodwa ngoku oluphantse lwalibaleka uphawu lwase-Italiya, ilivo likaLegnano lisusela ngo-1902 kunye noVittorio Rossi & Inkampani, ovelise iibhayisikile eMilan phantsi kwegama “Lignon” Kwiminyaka embalwa kamva, inkampani yathathwa ngu-Emilio Bozzi, owaseka elinye lawona maqela aphumeleleyo ngebhayisikile kwimbali ngo-1906, iQela leBhayisekile laseLegnano, elalibaleka de kwangowe-1966.

Iibhayisekile ezijongwa kakhulu zeLegnano zaye zahlulwa ngombala wazo owahlukileyo, owaziwa ngokuba yi-'Lizard Yellow ', kunye noyilo lwesakhelo esahlukileyo apho isitampu sokuhlala sasincanyathiselwe ngaphambili kwityhubhu yokuhlala ezantsi nje kwenxalenye ephezulu. Ngomnyaka we-1920 uBozzi wathatha u-Alberto da Guissano, umlindi waseLombard obonakalisa uphawu lweLegnano. Umfanekiso wayo, otyhidiweyo osikiweyo wobhedu kwaye uphakanyisiwe kwityhubhu yentloko, uya kuhombisa iibhayisekile zakho kwiminyaka engama-50 ezayo.

Isiphelo sophawu lwatshintsha unaphakade ngo-1924 xa iqela lasayina ikhontrakthi yobomi neenkwenkwezi ezisencinci ezinomnqweno uAlfredo Bindato. Yayiyingqondi kwezoshishino njengoko uBinda waphumelela ngempumelelo engathethekiyo ngePalmarès, kubandakanya nohlelo ezintlanu zeGiro d'Italia, izihloko ezintathu zeNdlela yeHlabathi, uKhenketho lweLombardis ezine kunye nohlelo ezimbini zeMilan-San Remo. Ngapha koko, u-Binda wayongamele kangangokuba abaququzeleli be-Giro bamhlawula imali elingana nayo yonke impumelelo e-Giro ukuze baphume kolu khuphiswano lowe-1930 ukuze bakhuthaze umdla kumntu ophantse wabonisa isihlandlo sesihlanu.

Oku kwangenisa ixesha legolide kuLegnano, kunye nokusayina kukaGino Bartali ngo-1936 kunye noFausto Coppi ngo-1939, kwaye emva kokwenza enye yezona zixhobo zinamandla ezinokutsha embalini, esi sibini sahlukana ngo-1942 xa uCoppi waqhekeza wagubungela iRiding Riding. imbangi uBianchi, yahlula ilizwe laba ziinkampu ezimbini kule nkqubo. Olu kruthakruthwano lwaqhubeka emva kweMfazwe yesibini (II) yeHlabathi, kunye no-Bartoli esenza uloyiso ngo-1948 eTour de France e-Legnano Roma ene-Campagnolo eyasebenza ngentonga yangasemva. Emva kokurhoxa kuka-Bartoli ngasekupheleni kuka-1954, ubutyebi bukaLegnano baphela ngokuthe chu kule minyaka ilandelayo, ngaphandle kwendondo yegolide kukhuphiswano lwendlela ye-Olimpiki yango-1956 kunye no-Ercole Baldini.

Inkampani yalwa ngendlela yayo ngee-1960s kunye nee-70s ngaphambi kokuba ithengwe liBianchi ixesha elide ngo-1987. Kwaye enye yokugqibela eyakhazimlayo xa uMaurizio Fondries waphumelela intshinga yePro World Road eRonse, eBelgium. Uphawu lweLegnano sti ll luza kuphila namhlanje egameni, eliphantsi kweCycleurope.

Kukho amabali anomdla ngokwenene phaya. Ndiyathemba ukuba kunjalo, kunjalo. Kodwa ndingathanda ukwazi ukuba zeziphi ii-iconic zebhayisikile zeempawu ongathanda ukuzibona kumanqaku alandelayo.

Shiya izimvo zakho apha ngezantsi, kwaye ukuba awukabhalisi kwi-GCN, ungenza njalo simahla ngokunqakraza iglobhu naphi na kwiscreen apha. Ukuba ulijongile eli nqaku ndicinga ukuba ukwindlela yeebhayisikile, ke ngoku ucofa nje apha ngezantsi? umboniso wethu wobugcisa omtsha, oqaqambileyo we-GCN.
