ibhayisikili
IShimano, iCampagnolo ne-SRAM bonke banikele ngokushintshwa kwe-elekthronikhi iminyaka eminingana, i-FSA isibajoyinile, kanti i-SRAM ivuselele uhlelo lwayo lwe-eTap lwaba yi-12-speed futhi yethula i-Force eTap engabizi kakhulu. Ngamabhayisikili aphelele asebenza ngogesi abiza cishe u- £ 2,400, ngabe kufanele ucabange ngokuhamba?
Amashifu athuthukisiwe
Ngabe kunembe kangakanani kunokushintshwa kwemishini kungaba amashifu kagesi? Yebo, ngohlelo lokukhanda, uma ucindezela isigwedlo ukuthi sisuke kwelinye ibhayisikili elixhunywe kolunye uye kolunye imeshi yangaphambili yenza okufanayo ngaso sonke isikhathi. Ngohlelo lwe-elekthronikhi imeshi yangaphambili isebenza ngokuhlukile ngokuya nge-sprocket okuyo ngaleso sikhathi.
Thatha uhlelo lwe-SRAM's eTap. Uma usuka ebhayisikili elincane elixhunywe ngeketanga uye ebhayisekilini elikhulu elixhunyanisiwe, ikheji ligudluka kancane ukusiza iketanga likwazi ukugxuma. Bese kuthi ingxenyana yomzuzwana kamuva, uma iketanga selikhuphukile lapho, ikheji lihlehla libuyele ngaphakathi endaweni yalo ejwayelekile.
Wisikhukhukazi uyashintsha usuka ebhayisikili elikhulu elixhunywe ngeketanga uye ochungechungeni oluncane, ikheji lihamba lingena ezigabeni ezimbili. Okokuqala, kugudluka ngokwanele ukuhambisa iketanga phansi. Bese kuthi ingxenyana yomzuzwana kamuva, uma iketanga seliphansi eringini elingaphakathi, lihamba kancane liwelele ngaphesheya. Ukwenza izinto ngale ndlela kugwema ukuthi kungenzeka ukuthi uchungechunge luphume ngaphakathi kwebhayisikili elixhunyanisiwe.
Izinga lezi zinto ezimbili ezenzeka ngalo lincike kwi-sprocket okuyo ngaleso sikhathi. Ithi uneketanga ebhayisikilini elincane elixhunywe ngamaketanga nakwesinye seziqhumane ezinkulu futhi ufuna ukushintshela kuloluchungechunge olukhulu. Imashi yangemuva yenza imeshi yangaphambili yazi ukuthi idinga ukweqa ngaphezulu kunalokho ebiyokwenza uma iketanga liqhubekele phambili ngaphandle kwelinye lamapulangwe amancane.
Iqiniso ukuthi uthola ukushintsha okuhle kakhulu nangaphansi komthwalo.
"IDura-Ace noma i-Ultegra Di2 ukushintshwa kwamagiya kagesi kuhambisa uchungechunge ngqo lapho ludinga ukuba khona lapho kuhleliwe ngaphambili noma ngemuva kwensimbi," kusho uShimano.
“Isayensi engemuva kwayo iyamangalisa futhi ibuye ihlelwe ngokuthanda kwakho okuguqukayo [bheka ngezansi]. Wenza umyalo futhi uhlelo luphendula ngokunembile ngaso sonke isikhathi. Esimweni somjaho ukwethembeka nokuzethemba okukhuthazayo kungasho umehluko phakathi kokwenza ikhefu noma cha. ”
Ukushintshwa okusheshayo
Uma ufuna ukushintshela ngaphesheya kwekhasethi ngohlelo lokushintsha kwemishini, udinga ukucindezela isigwedlo ngaphezu kwesisodwa (amasistimu ahlukile adinga izinombolo ezahlukahlukene zemishini). Ngezinhlelo ze-elektroniki ungashintsha ukusuka kolunye uhlangothi lwekhasethi uye kolunye uma ucindezela ubambe isigwedlo. Kulula nje kancane.
UCampagnolo uthi, "[Izikhathi zokushintsha kwe-EPS ezingemuva] manje seziyashesha ngama-25% kunezi-derailleur ezingemuva zomshini (kuthatha imizuzwana engu-0.352 ukushintsha ama-sprocket)".
Ungenza ngokwezifiso ukuguquka
NgeShimano Di2 ungenza ngezifiso ijubane eligudlukayo nenani lamagiya uhlelo oluzoshintsha uma ucindezela ubambe isigwedlo. Ungashintsha futhi imisebenzi ye-uphift lever ne-downshift lever, futhi nemisebenzi ye-lever yangakwesokunxele ne-lever efanele. Isistimu yokuqala ye-Red eTap ye-SRAM ibingenalo ikhono lokwenza ukushintsha ngokwezifiso, kepha amaqembu amabili amasha we-AXS 12-speed angenziwa ngezifiso ngohlelo lokusebenza lwe-smartphone.
Akukho ukugoqwa kwamaketanga
Uma uhlelo lweShimano Di2 noma lweCampagnolo EPS lusethwe kahle, noma ngabe uku-sprocket okuso awudingi ukulungisa isikhundla semashi yangaphambilini ukuvimbela ukuxubana kwamaketanga emapuletini ohlangothini lwe-mech ngaphambili ngoba kwenziwa ngokuzenzakalela.
Ngemuva kokuthi ushintshe isisihlakala esingemuva kwesinye isikhathi uzozwa i-whirr njengoba imeshi yangaphambili ihamba kancane ukubheka isikhundla esisha seketanga, umqondo ngukuthuthukisa ukusebenza kahle nokunciphisa ukugqoka.
I-SRAM ithi lokhu akudingekile ngohlelo lwayo lwe-eTap ngoba ayikho ingozi ye-chainrub noma ngabe usebenzisa yiphi i-chain chain / sprocket.
Ukusebenza okulula
Ukushintsha igiya ngohlelo lwe-elekthronikhi kudinga ukunyakaza kwesifinyezi okufushane kakhulu kunokufana nezinto ezilinganayo. Ucindezela nje inkinobho, awudingi ukushanela isigwedlo ngaphesheya.
Ukuhambisa izigaxa kuhlelo lokukhanda akuyona into ekhohlakele kakhulu emhlabeni, kepha kungafinyelela kancane uma ufuna ukuhambisa lonke uhla olutholayo. Izinto zilula kancane ngezinhlelo zobuchwepheshe.
Ngohlelo lwe-SRAM lwe-eTap isigwedlo esishifini esisodwa senza amashifu, isigwedli kwesinye ishifti senza ukwehla, bese ubadudula bobabili ngasikhathi sinye ukushintsha phakathi kwamaketanga. Kuyindlela elula ukuyisebenzisa, noma ngabe ugqoke amagilavu amakhulu noma ama-mittens kubanda.
Izinketho eziningi zokuma kokushintsha
Ebhayisikili lomgwaqo eline-Shimano noma i-SRAM ukushintshwa kwe-elekthronikhi uvame ukushintsha igiya nge-brake ehlanganisiwe nangama-gear shifters, kufana nokuthi ungaba nohlelo lwemishini, kepha ungangeza ama-satellite shifters kwenye indawo kubha yakho yokuphatha ukwenza kube lula ukushintsha igiya ezimeni ezithile, ikakhulukazi lapho kugijinywa.
Ngohlelo lwe-elekthronikhi, ungaba nama-shifters kuzandiso ze-aero naku-bar bar, ngakho-ke kulula ukushintsha igiya uma ungaphandle kwesihlalo lapho ukhuphuka noma uphuma ekhoneni eliqinile.
Ngohlelo lwe-elekthronikhi kuncane kakhulu ukugcinwa okujwayelekile futhi awusoze wadinga ukufaka ikhebula esikhundleni salo. Ukuhlenga okuncane, uma kukhona, kuyadingeka ngemuva kokusetha kokuqala.
Noma lokho kusethwa kokuqala kulula kakhulu ngohlelo lwe-SRAM's eTap. Akunantambo ngakho-ke asikho isidingo sokuhambisa izintambo ngohlaka lwakho.
Ukushintshwa kwemishini bekusebenza kahle iminyaka eminingi, eminingi futhi kuzoqhubeka nokwenza njalo, futhi kushibhile kakhulu kunokusetha ngogesi. Uma ungazitholi izinzuzo esizibhale ngenhla eziphoqelela ngokwanele ukukukholisa ukuthi ushintshele ku-elekthronikhi, akekho umenzi wezinto ozoyeka ukunikela ngokushintsha kwemishini noma kunini.
Okunye ukuphikiswa okuvame kakhulu kokuya ku-elekthronikhi ukuthi kungenzeka kuphume mahhala phakathi nohambo. Akunakwenzeka ukuthi kwenzeke ngaphandle kokuthi ungagxili empeleni. Uzothola amakhulukhulu wamamayela phakathi kokukhokhiswa kuzo zonke izinhlelo ze-elektroniki, kanye nesexwayiso esiningi sokuthi uphansi kujusi.
Noma ibhethri lihamba licabalele, ungafaka ngesandla iketango egiyeni oyifunayo bese ugibela ibhasi elilodwa.
Vele, awudingi ukwenza ushintsho ekushintsheni kwe-elekthronikhi.
"Ungathola nokushintsha okuqondile, okusheshayo nokusheshayo kusuka kuDura-Ace, Ultegra noma amagiya angama-105," kusho uShimano. “Ngale ndlela, kanye nokwenza umyalo - okusho ukusunduza kwesigwedlo - uphinde usebenzise uhlelo ngokudonsa noma ngokukhipha ikhebula.
“Kunobuciko obuthile bokusetha i-drivetrain yakho ngesandla ukuze uthole leli zinga lokusebenza kahle. Abagibeli abaningi bakhetha ukwazi ukuthi zisebenza kanjani zonke izingxenye zomuntu ngaphakathi kwe-drivetrain yabo, okulula ngohlelo lokukhanda.
“Ngohlobo ngalunye lokuhamba olunezinzuzo zalo, umbuzo ngukuthi ngabe ufuna ukuyala isitimela sakho sokushayela ngokucindezela inkinobho, noma ukusisebenzisa ngokomzimba usebenzisa i-lever. Mhlawumbe impendulo iwukuba ube nakho kokubili kuye ngemininingwane yohambo lwakho. ”
Abantu abaningi esibaziyo abaye bazama ukushintshwa kwe-elekthronikhi isikhathi esibalulekile bafuna ukunamathela kukho, kepha ukukhetha kungokwakho.
