Wenza ntoni xa ishishini lebhayisekile lingakwazi ukwenza iinxalenye ezihlangabezana neemfuno zakho ezithile?Ukuba uyinjineli yoyilo kunye nengcali yomoya uPaul Townsend, uya kwenza iimveliso zakho kwaye ube iinxalenye kwiimpawu ezikhuphisanayo.
UPawulos waphawula ngomsebenzi weteknoloji yendlela dead-end (kunye hydraulic rim iziqhoboshi) kunye unique SRAM-Shimano hacker photo yakhe, kufuneka sifunde ngakumbi.
Kwangoko ekuqaleni kwe-2016, imarike yeqela lendlela ibonakala ihluke kakhulu ngoku.I-Shimano akakayiqalisi i-disc yayo ye-Dura-Ace R9170 kunye nekhithi ye-combo ye-Di2 (ii-joystick ezingezizo i-R875 kunye neziqhoboshi ezihambelanayo kuphela kwe-hydraulic/Di2 ongakhetha kuyo), kunye ne-SRAM's Red eTap HRD kuseneenyanga kude.
UPaul wayefuna ukusebenzisa iziqhoboshi zehydraulic rim kwibhayisekile yakhe yendlela, kodwa akazange aneliseke ziiMagura brake calipers.
I-lever ye-SRAM ene-hydraulic rim brake inezaphulelo ezininzi.Ungumlandeli webhokisi yegiya ye-Shimano Di2, ngoko ke ugqibe ekubeni azidibanise ezi zimbini zibe yi-DIY mashup ekhethekileyo.
Oku kubandakanya ukufudusa i-lever yebrake kunye ne-shift iqhosha lokudityaniswa kunye nezixhobo zombane ezinxulumeneyo ukusuka kwiseti yee-Di2 joysticks ukuya kumzimba we-SRAM hydraulic road joystick.
Inkqubo ye-hydraulic ye-SRAM ihlala ingatshintshi, kodwa iqhutywe yi-Shimano lever blades, kunye nokutshintshwa kwegesi kusekelwe ngokupheleleyo kwi-Di2.
Ndabuza uPaul imibuzo ethile ukuze ndifunde ngakumbi malunga nokuseta kwakhe okungaqhelekanga: indlela asebenza ngayo, imvelaphi yakhe yobunjineli, kwaye yintoni elandelayo.Impendulo kaPawulos ihlelwe ubude kunye nokucaca.
Ngaphambi kokuba siqhubeke, kufuneka sibonise ukuba ukuguqula inkqubo yakho yokunyathela nayiphi na indlela kunokubangela ukulimala kakhulu, kwaye asikukhuthazi ukuba wenze oku.Uhlengahlengiso lwamacandelo luya kwenza kwakhona isiqinisekiso somenzi singasebenzi.
Ukusukela ngeminyaka yoo-1980s, bendikhwela ibhayisekile xa ndandifunda ubunjineli bomatshini kwiYunivesithi yaseCoventry Poly.Ngelo xesha ndandine-Topanga Sidewinder kunye nebhayisikili yentaba yaseMick Ives.
Ndisebenze kwimveliso yeebhayisikile kunye noseto lwesiko, kwaye bendiyinjineli yoyilo kunye nengcali yomoya ixesha elide.Ndiye ndatshintsha iimoto neebhayisekile kangangeminyaka emininzi.
NdineCanyon Ultimate ngo-2013 kwaye bendisoloko ndiyithanda itekhnoloji, ngoko ke ndaqale ndayixhobisa ngeShimano Ultegra 6770 Di2 iqela lekhebula langaphandle.
Emva koko, ndaziphucula iziqhoboshi ndaza ndazama iirim brakes zeMagura RT6 hydraulic rim.Ukuthetha ngokuphandle, bekunzima, kwaye kwakunzima ukuyifaka kunye nokuyifaka.
Ndenze i-clutch derailleur yesithuthuthu sam esingekho endleleni kwaye ndabeka i-Formula RR clone disc brake kuyo kunye ne-Di2 eguqukayo.Isebenze kakuhle, kodwa ngeli xesha, ixabiso le-SRAM HydroR i-hydraulic rim brakes kunye ne-levers kwiPlanethi-X yayiphantsi ngokuhlekisayo.
Emva kokufunda indlela amacandelo e-SRAM adibana ngayo kunye nokwazi indawo efunekayo kwimodyuli ye-Di2, ndathenga i-HydroR rim brake nge-£ 100.Kamva, ndathengela mna nezinye iiseti ezine, iqabane endandisebenza nalo nomntu waseUnited States.
Kwixesha elidlulileyo, ndenza amavili kunye neGravity Research Pipe Dream-style V iziqhoboshi kwizithuthuthu zam ezingekho endleleni, emva koko ndenze iimashup zezinye iibhayisekile.
Ke ngoko, imbono yethu yile: iibhuleki zediski zehydraulic zinokubamba okutyebileyo kunye nokunyuka okuncinci.I-Maguras ibuhlungu kwaye ihlazo, ngoko ke ukuba ndifuna ukuxhobisa ibhayisekile yendlela nge-hydraulic rim brakes, ndingakhetha i-SRAM, kodwa ndiyayithanda i-Di2.
Kunzima kangakanani ukudibanisa ezi zimbini?Emva kokususa indlela yokutshintsha isantya, kukho umngxuma omkhulu kumzimba wentonga ye-SRAM, ngoko ke impendulo yile: ilula kakhulu.
Ndithenge izixhobo zegiya ze-6770 Di2 ezisetyenzisiweyo.Ngenxa yokuba i-11-speed Ultegra 6870 Di2 yimveliso entsha, abantu abaninzi ngempazamo bathengise i-lever yegiya ye-6770 ukuze kuphuculwe [impazamo kuba i-6770 inokusetyenziswa nge-6870 derailleur].Ndicinga ukuba ndithenge ipere ye-leverage malunga ne-£ 50.
Ukuseta kwam kusebenzisa umngxuma we-pivot okhoyo kwilever ye-Di2 ye-brake, kwaye ityhala isinyithi kunye neplastiki yeprototyping ekhawulezayo (i-3D eprintiweyo) iinxalenye ze-Di2 ye-brake lever yasekuqaleni kwi-cylinder ye-brake master, ngoko ke amandla okwakhiwa akayi kuba phezulu kakhulu.umbuzo omnye.
Ndiyinqumle inxalenye engaphezulu ukusuka kumphezulu we-6770 Di2 isibambo, ndiyicubungule ngoomatshini, emva koko ndayincamathelisa kwinxalenye yenayiloni ekhawulezayo yokuchwetheza.
Ndiphinde ndawuphinda umngxuma ukwenza umngxuma ube mpuluswa kunye nobukhulu obufanelekileyo.Ngepeyinti encinci, okanye i-Shimano grey-green nail polish kule meko, ndilungele ukudibanisa yonke into.
Olu lungiselelo alusebenzisi i-spare rod return spring okanye i-E-clip ukulungisa ishaft, ngoko ke i-shaft iyagrunjwa kwaye icofe ukuze kufumaneke isikrufu se-countersunk esintloko yayo inkulu kune-pivot pin.Emva kokuba umzimba we-lever uhlile kancinci, intloko iyagungxula.
I-conical return spring yongezwa kwi-brake master cylinder shaft ukubonelela ngamandla okubuyisela kwi-lever.
Emva koko, ukuguqulwa kuphela endikwenzileyo kukongeza i-O-ring encinci ye-cross-sectional kwi-E-clamp groove ye-pivot ye-pivot ukukhusela i-lever blades ukuba iqhube kancinci.
Intambo ye-Di2 idlulela kwi-groove kwicala elingezantsi le-3D eprintiweyo yeplastiki yentloko ye-lever ye-brake, ngoko igxininiswe kwaye ayiyi kuxinga okanye iguge.
Emva kokususa zonke iindlela zokutshintsha, ekuphela kwendlela yokuguqula iinxalenye ze-SRAM kukufayila iigrooves ukubeka intambo ye-Di2.Imodyuli ye-Di2 igxininiswe kunye neqhekeza le-foam kwindawo esemva.
Ndaphinda ndaqhuba inkqubo ye-sprint shifter eqhekekileyo, edibanisa i-Dura-Ace 7970 Di2 endala yokutshintsha ukusuka kwi-SW-R600 yokukhwela i-shift switch ukuya kwimodyuli ye-elektroniki, kwaye zonke iitshintshi zixhunywe kwintonga ekhohlo.Intambo yandiswa ukubonelela ngesisombululo seplagi ecocekileyo, kwaye xa ndiqhuba iCanyon clone edibeneyo yokumisela isibambo se-lever, ibhokisi yeJunction'A'Di2 kwi-shaft yayikuyo.
Iziqhoboshi zinezifakelo ze-titanium kunye nezibiyeli ezilula zeziqhoboshi.Zifakwe kwisakhelo se-52 cm.Ubunzima bubonke bamavili angaphambili yi-375g, ubunzima bubonke bamavili angasemva yi-390g, kunye nobunzima bamavili angasemva yi-390g.
Ewe, ndifuna ukuthi ibe yimpumelelo.Ndithengisele umntu oseHong Kong iseti, owandithumelela ne-SRAM Red kunye ne-Dura-Ace ukwenza le mashup.
Ndathengisa esinye isixhobo kumntu waseOstreliya awayeza kusisebenzisa kwibhayisekile yakhe iTT, ndaza ndathengisa isinye kwisithathu kumntu waseUnited States, ukuze ndikwazi ukuhlawula zonke iindleko zam.
Ukuba ndihlawula ixabiso elipheleleyo lakho konke oku, kuya kuba yingozi enkulu.Ngapha koko, ndingahlala ndibuyisela iinxalenye ze-SRAM kwisitokhwe sokutshintsha koomatshini ngaphandle kweengxaki.
Mhlawumbi ndiya kunika i-lever umthombo onamandla wokubuya.Ndidinga isitshixo somsonto ukunqanda utshintsho kuluhlu lokuhamba ngexesha lokuqhuba, kuba ndisikhulule ngokupheleleyo isilungisi sebrake ndakhulula isitshixo somsonto sokuqala.
Ewe, ndiphuhlisa ukukhwela amatye amatsha kunye nelever yegiya ebalekayo, kwaye ndijonge ilungiselelo elahlukileyo apho i-lever yegiya yangaphambili iya kuba sisincedisi esincedisayo, njengeepaddles kwi-Campagnolo gear lever.
Umbono wokuqala wawuyi-right-hand upshift kunye ne-hand-downshift ezantsi, kwaye ndisazama ukusebenzisa i-lever blade.
Ndiyakwazi ukuncamathela kwiincakuba ze-SRAM ze-brake lever okanye ndisebenzise i-Campagnolo, kwaye emva koko ndigcine ii-lever ze-SRAM ze-gearbox ye-derailleur yangasemva kunye ne-levers ezintsha ze-front derailleur gearbox.
Oku kufuneka kuthetha ukuba akuyi kubakho ukungahambi kakuhle naxa unxibe iiglavu, ezinokuthi zibe yingxaki ebusika phantsi komgangatho weShimano.
