I-Specialized ilahle uyilo lwayo lwesiqhelo yakhetha isihlalo esiguquguqukayo nesijikelezayo.
Ubulungu bangaphandle buhlawuliswa minyaka le. Ubhaliso oluprintiweyo lufumaneka kuphela kubemi baseMelika. Ungarhoxisa ubulungu bakho nangaliphi na ixesha, kodwa akuyi kubakho mbuyekezo kwiintlawulo ezenziweyo. Emva kokurhoxiswa, uya kuba nokufikelela kubulungu bakho kude kube sekupheleni konyaka ohlawulelwayo. Iinkcukacha ezithe vetshe
Ngamanye amaxesha, ezinye zezinto ezintsha zamva nje kwishishini leebhayisekile zibonakala zongeza ubunzima obungaphezulu kunokuba kufanelekile. Kodwa azizo zonke iindaba ezimbi. Kukwakho neengcinga ezintle zokwenza ibhayisekile ibe lula kwaye ibe ngcono.
Ngamanye amaxesha uyilo oluhle lubuza into ongayidingiyo xa kuthelekiswa noyilo oluntsonkothileyo lokuxhoma okanye izixhobo ze-elektroniki ezongeziweyo. Eyona nto ingcono, ukulula kuthetha ukwenza iibhayisekile zibe lula, zithule, zitshiphu, zibe lula ukuzigcina kwaye zithembeke ngakumbi. Kodwa kungekuphela nje oko. Isisombululo esilula sikwanazo nobuchule kunye nobuchule.
Utshintsho luye lwashiya iqonga elixhonyiweyo leSpur laza lakhetha inkqubo yokuxhasa elastiki elula.
Kukho isizathu sokuba phantse yonke ibhayisekile ye-XC ngoku ibe "ne-flex pivot" endaweni ye-pivot yendabuko ene-bearings okanye i-bushings. Ii-flex pivots zilula, zisusa iindawo ezininzi ezincinci (ii-bearings, ii-bolts, ii-washers...) kunye nokugcinwa. Ngelixa ii-bearings kufuneka zitshintshwe rhoqo ngexesha lonyaka, ii-flex pivots ezenziwe ngononophelo ziya kuhlala ixesha elide kwifreyimu. Ii-pivots ezingasemva kwefreyimu, nokuba zikwi-seatstays okanye kwi-chainstays, zihlala zibona kuphela ii-degrees ezimbalwa zokujikeleza kuhambo lwe-suspension. Oku kuthetha ukuba ii-bearings zinokuqhekeka kwaye ziguge ngokukhawuleza, ngelixa amalungu e-flexible frame enziwe nge-carbon, intsimbi okanye ne-aluminium anokwamkela ngokulula olu luhlu lwentshukumo ngaphandle kokudinwa. Ngoku zihlala zifumaneka kwiibhayisekile ezinohambo lwe-120mm okanye ngaphantsi, kodwa ii-flex pivots zokuhamba ixesha elide zenziwe, kwaye ndicinga ukuba siza kubona ezinye zazo njengoko iteknoloji yokuvelisa iphucuka.
Kwabakhweli beebhayisekile zeentaba abakhutheleyo, iingenelo zokusebenzisa i-one-by zinokuba zicacile kangangokuba zibonakala ngathi ziyazimela. Zisivumela ukuba sisuse ii-front derailleurs, ii-front derailleurs, iintambo kunye (ngokwesiqhelo) nezikhokelo zeetyathanga, ngelixa zisabonelela ngeendidi ngeendidi zeegiya. Kodwa kubakhweli abasaqalayo, ukulula kwe-shifter enye kuluncedo ngakumbi. Akulula nje ukuzifaka nokuzilungisa, kodwa kulula nokuzikhwela kuba kufuneka ucinge nge-shifter enye kunye neegiya ezisasazwa rhoqo.
Nangona zingentsha kangako, ngoku ungathenga ii-hardtails zodidi lokuqala ezinee-drivetrains ezifanelekileyo ze-single-ring. Le yinto elungileyo kakhulu kumntu oqalayo kulo mdlalo.
Ndiqinisekile ukuba kuza kubakho ukugxekwa okuninzi ukukhusela i-single pivot, kodwa nantsi into esiyenzayo. Kukho ukugxekwa okubini kweebhayisekile ezine-single-pivot. Eyokuqala inxulumene nokuqhobosheka kwaye isebenza kwiibhayisekile ezine-single-pivot eziqhutywa yi-link kunye neebhayisekile ezine-single-pivot zokwenyani.
Isizathu esiphambili sokusebenzisa uyilo kwi-single pivot eqhutywa yi-link (eyona ndlela ixhaphakileyo namhlanje) kukunciphisa nokulungisa uphawu lwe-anti-rise, oluyimpembelelo yamandla okuqhobosha kwi-suspension. Oku kuthiwa kuvumela i-suspension ukuba ihambe ngokukhululekileyo phezu kwamaqhuma xa iqhobosha. Kodwa eneneni, ayisiyonto inkulu. Enyanisweni, amaxabiso aqhelekileyo aphezulu okuqhobosha kwi-single pivots azinceda ukuba zimelane nokuntywila kwe-brake, nto leyo ezenza ziqine ngakumbi xa ziqhobosha, kwaye ndicinga ukuba isiphumo sibonakala ngakumbi. Kubalulekile ukukhankanya ukuba kule minyaka idlulileyo, iibhayisekile ezine-axle eziqhutywa yi-linkage ezivela kwiinkampani ezifana nazo ziphumelele iiNdebe zeHlabathi ezininzi kunye nemidyarho.
Isigxeko sesibini sisebenza kuphela kwiibhayisekile ezine-axle enye, apho isigqubuthelo sifakwe ngqo kwi-swingarm. Ngokuqhelekileyo azinazo ii-frame progression, nto leyo ethetha ukuba naluphi na uphuhliso okanye "ukunyuka" kwisantya sentwasahlobo kufuneka luvele kwi-shock. Ngokudibanisa okuqhubekekayo, amandla okudambisa ayanda ekupheleni kwesigqubuthelo, nto leyo enceda ngakumbi ekuthinteleni ukuwela ezantsi.
Kubalulekile ukukhankanya kuqala ukuba ezinye zezona zakhiwo zintsonkothileyo, njengeSpecialized's, aziphucukanga ngaphezu kwezinye ii-single pivots. Kwakhona, ngee-air shocks zanamhlanje, inkqubo yokulungisa iisprings ngee-volume shims ilula kakhulu. Kuxhomekeke ekubeni ubuza bani, amazinga okunciphisa umbane axhomekeke kwi-stroke avela kwii-progressive linkages ayisoloko ilungile. Yiyo loo nto ukwenza ibhayisekile esezantsi ene-progressive link yokuqhuba i-spring (coil) kunye ne-linear link yokuqhuba i-damper.
Kuyavunywa ukuba, unxibelelwano oluqhubekekayo lunokusebenza ngcono kwabanye abantu kunye nezinye izinto ezibangela ukushwabana, kodwa ngokuseta okufanelekileyo kokushwabana, i-single pivot isebenza kakuhle. Ufuna nje i-spring eqhubekekayo ngakumbi kunye/okanye ukuhla kancinci kancinci. Ukuba awundikholelwa, ungafunda uphononongo oluhle lweebhayisekile ze-single-pivot ezivela kwabanye abavavanyi apha napha.
Sekunjalo, ndicinga ukuba ukuxhumanisa okuqhubekekayo ngokubanzi kungcono ngokwembono yokusebenza. Kodwa xa kukho izinto ezitshintshileyo, ii-single pivots zisebenza kakuhle nakuthi thina singengabo abadlali abadumileyo, kwaye ukutshintshana okulula kwe-bearing kuzenza zibe lukhetho olufanelekileyo kwabo bakhwele udaka oluninzi.
Kukho iindlela ezininzi ezinzima zokuzama ukuphucula ukusebenza kwe-suspension: ii-links ezintle, ii-shock absorbers ezibizayo, ii-idlers. Kodwa kukho indlela enye eqinisekileyo yokunceda ibhayisekile igubungele amaqhuma: yinike uhambo olungakumbi lwe-suspension.
Ukongeza uhambo akuthethi ukuba kufuneka kongeze ubunzima, iindleko, okanye ubunzima, kodwa kutshintsha ngokusisiseko indlela ibhayisekile ekwazi ngayo ukufunxa uloyiko. Nangona kungenguye wonke umntu ofuna uhambo olugobileyo, ungayikhwela ibhayisekile yakho oyithandayo yomgama omde ngokunciphisa ukugoba, ukusebenzisa ukutshixa ngaphandle, okanye ukongeza izithuba zomthamo, kodwa awunakuhamba nawe njengebhayisekile ethambileyo yohambo olufutshane.
Anditsho ukuba wonke umntu makakhwele ibhayisekile ehlayo, kodwa ukunika ibhayisekile emdaka uhambo olungaphezulu nge-10mm kunokuba lula kwaye kusebenze ngakumbi ekuphuculeni umkhondo, ukubamba, kunye nentuthuzelo kunoyilo oluntsonkothileyo lokuxhoma.
Ngokufanayo, kukho iindlela ezininzi eziphucukileyo zokuphucula ukusebenza kokuqhobosha, ezifana neerotor eziphefumlayo, iirotor ezineziqwenga ezimbini, ii-brake pads ezifinniweyo, kunye nee-lever cams. Uninzi lwezi zongeza iindleko kwaye ngamanye amaxesha iingxaki. Ii-Fin pads zihlala zirhashaza, kwaye ii-lever cams zinokwandisa ukungangqinelani okanye ukuyekelela kwenkqubo ye-hydraulic.
Ngokwahlukileyo koko, iirotha ezinkulu ziphucula amandla, ukupholisa kunye nokuhambelana ngaphandle kokongeza ubunzima. Xa kuthelekiswa neerotha ezingama-200mm, iirotha ezingama-220mm ziya kwandisa amandla malunga ne-10% ngelixa zibonelela ngommandla omninzi wokususa ubushushu. Ewe, zinzima, kodwa kwimeko yeerotha, iidiski zinobunzima obumalunga ne-25 grams kuphela, kwaye ubunzima obungaphezulu bunceda ukufunxa ubushushu ngexesha lokubhuleka okunzima. Ukuze wenze izinto zibe lula, ungazama iirotha ezingama-220mm kunye neebhuleki zeembiza ezimbini endaweni yeerotha ezingama-200mm kunye neebhuleki zeembiza ezine; iibhuleki zeepiston ezimbini kulula ukuzigcina kwaye kufuneka zithelekiswe ngobunzima nangamandla.
Andifuni ukunika umbono wokuba yiLuddite. Ndiyawuthanda ubuchwephesha obenza ibhayisekile isebenze ngcono, nokuba yinxalenye encinci nje. Ndingumlandeli omkhulu wee-dropper posts zokuhamba ixesha elide, iikhasethi zesantya ezili-12, ii-tire inserts, kunye nezipringi zomoya ezinamandla aphezulu kuba zibonelela ngeenzuzo ezibonakalayo. Kodwa apho uyilo oluneendawo ezimbalwa lusebenza kakuhle kwihlabathi lokwenyani, ndingathanda ukusebenzisa indlela elula ngalo lonke ixesha. Ayikokugcina nje iigram okanye imizuzu embalwa evenkileni; isisombululo esilula nesinokwanelisa singaba cocekileyo kwaye sibe sihle ngakumbi.
Bhalisa ukuze ufumane iindaba zamva nje, amabali, uphononongo kunye nezibonelelo ezikhethekileyo ezivela kwiBeta kunye neebhrendi zethu ezihambelanayo, ezithunyelwa kwibhokisi yakho yokungenayo.
