Ukutshintsha kombane kwibhayisekile nganye

I-Shimano, i-Campagnolo kunye ne-SRAM zonke zibonelele ngokutshintshwa kwe-elektroniki iminyaka eliqela, i-FSA ijoyine, kwaye i-SRAM ihlaziye inkqubo yayo ye-eTap ukuya kwi-12-speed kwaye yazisa i-Force eTap engabizi kakhulu. Ngeebhayisekile zeshifti ze-elektroniki ezipheleleyo ezixabisa malunga ne-£2,400, ngaba ufanele ukuba ucinga ngokuthabatha uhambo?

Iinguqu eziphuculweyo
Ingaba ichane kangakanani kunokutshintsha koomatshini? Ewe, ngenkqubo yoomatshini, ukuba utyhala i-lever ukuba ihambe ukusuka kwelinye ibhayisekile ukuya kwelinye i-mech yangaphambili yenza okufanayo ngalo lonke ixesha. Ngenkqubo ye-elektroniki i-mech yangaphambili isebenza ngokwahlukileyo ngokuxhomekeke kwi-sprocket okuyo ngelo xesha.

Thatha inkqubo ye-eTap ye-SRAM. Xa usuka kwibhayisekile encinci yekhonkco ukuya kwibhayisekile enkulu yokubopha, ikheji idlula kancinci ukunceda ikhonkco ukuba litsibe. Ke iqhezu lesekondi kamva, xa ikhonkco liphezulu, ikheji ibuyela ngaphakathi kwindawo yayo eqhelekileyo.

WIsikhukukazi usuka kwibhayisekile enkulu yokubopha ikhonkco ukuya kwikhonkco elincinane, ikheji ishukuma ngaphakathi ngezigaba ezibini. Okokuqala, itshintsha ngokwaneleyo ukuhambisa ikhonkco phantsi. Emva koko iqhezu lomzuzwana kamva, nje ukuba ikhonkco lisezantsi kwisangqa sangaphakathi, lihamba kancinci ngaphaya. Ukwenza izinto ngale ndlela kunqanda ukuba kungenzeka ukuba ikhonkco liphume ngaphakathi kwibhayisekile yokubopha.

Ubungakanani bokuba ezi zinto zimbini zenzeka kangakanani kuxhomekeke kwi-sprocket okuyo ngelo xesha. Yithi unayo ikhonkco kwibhayisekile encinci yokubopha kunye nenye yee-sprockets ezinkulu kwaye ufuna ukutshintshela kwikhonkco elikhulu. I-mech yangemva yenza i-mech yangaphambili yazi ukuba ifuna ukugqitha ngaphezulu kunokuba ibinokwenzeka ukuba ikhonkco belingaphaya kwenye yeeprothini ezincinci.

Undoqo kukuba ufumana utshintsho olubalaseleyo naphantsi komthwalo.

"I-Dura-Ace okanye i-Ultegra Di2 ye-electronic gear shifting ihambisa ikhonkco ngqo apho kufuneka ibe khona ngeprogram ehleliweyo okanye indawo ye-derailleur yangasemva," utsho uShimano.

“Inzululwazi ngasemva kwayo iyamangalisa kwaye iyakwazi ukucwangciswa kukhetho lwakho oluthile [jonga ngezantsi]. Wenza umyalelo kwaye inkqubo iphendula ngokuchanekileyo ngalo lonke ixesha. Kwimeko yogqatso ukuthembeka kunye nokuzithemba okukukhuthazayo kunokuthetha umahluko phakathi kokuphumla okanye ukungaphumli.”

Ukutshintsha ngokukhawuleza
Ukuba ufuna ukutshintshela ngaphaya kwekhasethi ngenkqubo yokutshintsha ngomatshini, kufuneka ucinezele i-lever ngaphezu kwesihlandlo esinye (iinkqubo ezahlukeneyo zifuna amanani ahlukeneyo okushicilela). Ngeenkqubo ze-elektroniki ungatshintshela kwelinye icala lekhasethi uye kwelinye xa ucinezela ubambe i-lever. Kulula kancinci nje.

UCampagnolo ubanga ukuba, "[i-EPS yasemva kwe-derailleur] amaxesha okutshintsha ngoku yi-25% ngokukhawuleza kunomatshini ongasemva we-derailleur (kuthatha nje imizuzwana eyi-0.352 ukutshintsha i-sprockets)".

Unokwenza ngokwezifiso utshintsho
NgeShimano Di2 unokwenza ngokwezifiso isantya sokutshintsha kunye nenani leegiya inkqubo iya kutshintsha xa ucinezela kwaye ubambe i-lever. Ungatshintsha kwakhona imisebenzi ye-lever ye-upshift kunye ne-lever ye-downshift, kunye nemisebenzi ye-lever yasekhohlo kunye ne-lever yasekunene. Inkqubo yokuqala ye-SRAM ye-Red eTap yayingenakho ukukwazi ukwenza utshintsho, kodwa amaqela amabini amatsha e-AXS 12-isantya anokwenziwa ngokwezifiso nge-app ye-smartphone.

Akukho rub ngetsheyini
Nje ukuba inkqubo ye-Shimano Di2 okanye ye-Campagnolo EPS isethwe ngokuchanekileyo, nokuba yeyiphi na into oyifunayo awusoze ufune ukuhlengahlengisa indawo ye-mech yangaphambili ukuthintela ukurabha kwetyathanga kwiipleyiti zangaphambili ze-mech kuba yenziwe ngokuzenzekelayo.

Emva kokuba utshintshe i-derailleur yangasemva uya kuva i-whirr ngamanye amaxesha njengoko i-mech yangaphambili ishukuma kancinci ukuze ithathele ingqalelo indawo entsha yekhonkco, uluvo kukuphucula ukusebenza kakuhle kunye nokunciphisa ukunxiba.

I-SRAM ithi oku akuyomfuneko ngenkqubo yayo ye-eTap kuba akukho ngozi ye-chainrub nokuba usebenzisa yeyiphi i-chainring/sprocket combo.

Umsebenzi olula
Ukutshintsha igiya ngenkqubo yombane kufuna intshukumo emfutshane kakhulu ye-lever kunee-mechanical equivalents. Ucofa nje iqhosha, awusoze ufune ukutshayela i-lever ngaphesheya.
Ukuhambisa i-levers kwinkqubo yoomatshini ayisiyonto ikhohlisayo emhlabeni, kodwa inokuba yinto yokufikelela kancinci ukuba ufuna ukutshintshela kulo lonke uluhlu olukhoyo kuwe. Izinto zilula kancinci ngeenkqubo zombane.

Ngenkqubo ye-eTap ye-SRAM i-lever kwi-shifter enye yenza i-upshifts, i-lever kwenye i-shifter yenza i-downshifts, kwaye uyabatyhala bobabini ngaxeshanye ukuba batshintshe phakathi kwamakhonkco. Yinkqubo elula kakhulu ukuyisebenzisa, nokuba unxibe iiglavu ezinkulu okanye iimittens kwimozulu ebandayo.

Iinketho ezininzi zeshifti
Kwibhayisekile yendlela ene-Shimano okanye i-SRAM yokutshintsha kwe-elektroniki udla ngokutshintsha igiya usebenzisa i-brake edityanisiweyo kunye nezishifter zegiya, kuninzi njengokuba ubuya kwenza ngenkqubo yomatshini, kodwa unokongeza ii-satellite shifters kwenye indawo kwi-handlebar yakho ukuze kube lula ukutshintsha igiya. kwiimeko ezithile, ngakumbi xa ubaleka.

Ngenkqubo ye-elektroniki, unokuba ne-shifters kwizandiso ze-aero kunye ne-bar yesiseko, ngoko kulula ukutshintsha i-gear ukuba uphumile kwisali xa ukhwela okanye uphuma kwikona eqinile.

Ngesixokelelwano sombane kukho ulungiso oluncinane kakhulu lwesiqhelo kwaye awusoze ufune ukutshintsha intambo. Okuncinci, ukuba kukho, ukulungiswa kuyafuneka emva kokuseta kokuqala.

Kwanoseto lokuqala lulula kakhulu ngenkqubo ye-eTap ye-SRAM. Ayinacingo ngoko akukho mfuneko yokuba uhambise iintambo kwisakhelo sakho.

Ukutshintsha oomatshini bekusebenza kakuhle iminyaka emininzi, kwaye kusaza kuqhubeka ukwenza njalo, kwaye kunexabiso eliphantsi kakhulu kunolungiselelo lombane. Ukuba awuzifumani iibhenefithi esizidwelise ngasentla zinyanzelisa ngokwaneleyo ukukukholisa ukuba utshintshele kwi-elektroniki, akukho menzi wecandelo oza kuyeka ukunika ukutshintshwa koomatshini nangaliphi na ixesha kungekudala.

Enye yezona zinto zixhaphakileyo zokuchasa ukuya kwi-elektroniki kukuba kunokwenzeka ukuba uphelelwe yintlawulo phakathi kohambo. Ayinakwenzeka loo nto ngaphandle kokuba ngokwenene awugxininisi. Uza kufumana amakhulu eemayile phakathi kweentlawulo kuzo zonke iinkqubo zeshifti ye-elektroniki, kunye neninzi yesilumkiso sokuba uphantsi kwijusi.

Nokuba ibhetri ihambe tyaba, ungafaka ngesandla ikhonkco kwigiya oyifunayo kwaye ukhwele isantya esisodwa ukuya ekhaya.

Ewe, akukho mfuneko yokuba wenze utshintsho kwi-electronic shift.

"Unokufumana ngokuchanekileyo, ngokukhawuleza nangokuchanekileyo ukusuka kwi-Dura-Ace, i-Ultegra okanye i-105 yeegiya," utshilo uShimano. “Ngale ngqiqo, ngokunjalo nokwenza umyalelo – okt ukutyhala isixhasi – ukwasebenzisa inkqubo ngokutsala okanye ukukhulula intambo.

“Kukho ubugcisa obuthile bokuseta i-drivetrain yakho ngesandla ukuze ufumane eli nqanaba lokusebenza kakuhle. Uninzi lwabakhweli bakhetha ukwazi indlela yokusebenzisa icandelo ngalinye ngaphakathi kwe-drivetrain yabo, elula ngenkqubo yoomatshini.

“Kuhlobo ngalunye lokutshintsha lunezimfanelo zalo, umbuzo ngowokuba uyafuna na ukuyalela uloliwe wakho wokuqhuba ngokucofa iqhosha, okanye uwusebenzise ngokwasemzimbeni usebenzisa i-lever. Mhlawumbi impendulo kukuba zombini zixhomekeke kwiinkcukacha zohambo lwakho. "

Uninzi lwabantu esibaziyo abaye bazama ukutshintshwa kwe-elektroniki ixesha elibalulekileyo bafuna ukunamathela kuyo, kodwa ukhetho lolwakho.
