Sele kudlule iminyaka emine ukusukela oko i-FSA yaqalisa iqela layo le-K-Force WE (Wireless Electronic) elinesantya esi-11, kwaye kungaphantsi kweminyaka emibini emva kohlobo lwayo lwe-disc brake. Kodwa namhlanje, inkampani ibhengeza ukuba iza kusebenzisa isantya esi-12 ngeqela le-K-Force WE 12 disc brake. Ngokwemvelo, ifuna ukwakha phezu kwezizukulwana zangaphambili kwaye ikhuphisane ngokuthe ngqo neqela le-electronic road bike elinesantya esi-12 ezivela kwiBig Three – Shimano, SRAM kunye neCampagnolo.
Kodwa akuphelelanga apho. Le khithi yakhululwa ngaxeshanye neemveliso ezininzi zale nkampani, eziquka iindlela, iintaba, iigrabile kunye neebhayisekile ze-elektroniki.
I-FSA ichaza i-"drivetrain ehlaziyiweyo," uninzi lwezinto ze-K-Force WE 12 zifana kakhulu nezinto ze-11-speed ezikhoyo ngoku, kodwa ukongeza ekuphuculweni ukuya kwi-12 sprockets, kukho ezinye iindlela zoyilo kunye nokugqiba ukuphucula ukusebenza kunye nobuhle.
Ikhithi ye-WE inee-shifters ezingenazingcingo ezithumela imiyalelo yokutshintsha kwimodyuli yokulawula ephezu kwe-derailleur engaphambili. Zombini ii-derailleurs ziqhagamshelwe ngokwasemzimbeni kwibhetri efakwe kwityhubhu yesihlalo, oko kuthetha ukuba le khithi ayinazingcingo ngokupheleleyo, kodwa ibizwa ngabaninzi njenge-semi-wireless.
Ngaphandle kwemizobo emitsha nengabonakaliyo, umzimba we-shift lever, i-kinked brake lever kunye neqhosha le-shift zithwala i-ergonomics ekhoyo, edumileyo kwaye zibonakala zingatshintshanga ngaphandle. Oku kunjalo nakwii-disc calipers, ngelixa i-shifter igcina i-compact master cylinder yayo, uhlengahlengiso lwe-range yee-compound lever blades, ii-exhaust ports ezifakwe phezulu kunye ne-CR2032 coin cell wireless transmission.
Ubunzima obufunekayo be-shifter nganye kunye ne-caliper (kuquka i-brake hose kunye ne-oyile) bubunzima obuyi-405 grams, 33 grams kunye ne-47 grams, ngokulandelelana, kunobunzima obufunekayo benkampani be-11-speed WE Disc shifters. Iintsimbi zangaphambili zazingenazo ii-brake pads, kodwa iintsimbi ezinikezelwa kwi-caliper ezintsha azikhankanyi.
I-derailleur entsha engasemva ibonakala ngathi yahlukile kwinguqulelo ye-11-speed kuphela ngokugqitywa nangobunzima, inemizobo emitsha efihlakeleyo kunye neegram ezingama-24 ezongezelelweyo. Isenomthamo ophezulu womthwalo weetoni ezingama-32 kunye ne-pulley ye-FSA yokugijima, kwaye mhlawumbi ayinayo i-return spring, esebenza njengengalo yerobhothi kunendlela yendabuko yokubuyela umva ye-parallelogram.
I-derailleur engaphambili ihlala ingumongo womsebenzi, njengoko ifumana imiqondiso engenazingcingo evela kwi-shifter kwaye ilawula zonke izinto ezitshintshayo zenkqubo.
Ingena kwi-brazed mount eqhelekileyo, igcina ukulungiswa kwayo ngokuzenzekelayo, kwaye inexesha lokutshintsha eliqikelelweyo le-70ms. Ngokungafaniyo nomthamo we-sprocket ophezulu wenguqulo yesantya se-11-tooth tooth eyi-16, imodeli yesantya se-12 inamazinyo ayi-16-19. Ngaphandle kwemizobo engachazwanga kangako "ye-12", umzimba wayo omde, omkhulu ujongeka ufana, kodwa isakhelo sentsimbi sicociwe kwaye izikrufu ezibonakalayo ezingasemva azibonakali. Ubunzima obuqikelelweyo buncitshisiwe ukusuka kwi-162 grams ukuya kwi-159 grams.
I-FSA idibanise i-groupset entsha ye-WE 12-speed kunye ne-crankset yayo ye-K-Force Team Edition BB386 Evo. Inomtsalane ngakumbi kune-crankset zangaphambili ze-K-Force, ine-crank ezingenanto ze-3K carbon composite kunye nee-chainrings ze-CNC AL7075 ezifakwe ngqo kwi-one-piece.
I-FSA ithi ii-chainrings ezimnyama ezifakwe i-anodized, ezifakwe isanti ziyahambelana nee-drivetrains ze-Shimano, SRAM kunye ne-FSA ezinesantya esili-11 kunye ne-12. Ii-axles ze-BB386 EVO zi-alloy enobubanzi obuyi-30mm kunye noluhlu lweebrakethi ezisezantsi ze-FSA eziqinisekisa ukuhambelana okubanzi.
Ubude bee-crank ezikhoyo yi-165mm, 167.5mm, 170mm, 172.5mm kunye ne-175mm, kwaye ii-chainrings ziyafumaneka kwiindidi ezingama-54/40, 50/34, 46/30. Ubunzima beeringi ezingama-54/40 buyi-544 grams.
Utshintsho olukhulu olubonakalayo kwikhithi ye-FSA ye-K-Force WE yi-sprocket yayo eyongezelelweyo. I-flywheel isakhiwe nge-cast-piece enye, i-heat-treat carrier, kwaye i-sprocket enkulu yi-electroless nickel plated. I-sprocket encinci yi-titanium kwaye ikhasethi ifumaneka ngobukhulu obuyi-11-25, 11-28 kunye ne-11-32. I-FSA ithi ikhasethi yayo entsha ye-11-32 12-speed inobunzima obuyi-195 grams, obukhaphukhaphu kakhulu kunekhasethi yangaphambili ye-11-28 speed 11 kwi-257 grams.
Ichazwe yi-FSA njengezolileyo nesebenzayo, olu luhlu lwe-K-Force lunee-hollow pins, ububanzi obuyi-5.6mm kunye ne-nickel-plated finish, kwaye kuthiwa lunobunzima obuyi-250 grams kunye nee-links ezili-116, xa kuthelekiswa ne-246 grams kwii-links ezili-114 zangaphambili.
Iirotha ze-K-Force WE zinoyilo lwerotha oluneziqwenga ezibini olune-aluminium carrier eyenziwe ngobumba, iringi yentsimbi engagqwaliyo egayiweyo kunye nemiphetho ejikelezileyo ye-center lock okanye ii-six-bolt hubs, ububanzi obuyi-160mm okanye i-140mm. Ubunzima bazo obuceliweyo bunyukile ukusuka kwi-100g kunye ne-120g kwi-140mm kunye ne-160mm ngokulandelelana ukuya kwi-103g kunye ne-125g.
Kwenye indawo, ibhetri eyi-1100 mAh efakwe kwityhubhu yesihlalo sangaphakathi inika amandla ii-derailleurs ezimbini ngocingo oluqhotyoshelweyo, kwaye kufuneka inike ixesha elifanayo okanye eliphuculweyo lokusetyenziswa phakathi kokutshaja. Inkqubo yokuqala ye-WE kwakufuneka ivulwe ngeqhosha elikwi-derailleur yangaphambili ngaphambi kokuba isetyenziswe, kwaye ihambe kwimo yokulinda emva kwexesha elithile lokungasebenzi. Ngaphambili yayitshajwa ngokutshintsha intambo ye-derailleur yangaphambili ngetshaja. Nangona ibhetri kunye nocingo kubonakala ngathi azitshintshanga, okwangoku akukho lwazi ngale nkqubo okanye ubomi bebhetri obulindelekileyo.
Kwakhona namhlanje kubhengezwe imitha entsha yamandla ye-FSA, esekelwe kwi-crankset ye-aluminium ye-AL6061/T6 eyenziwe ngobumba olubandayo ene-axles ze-MegaExo 24mm okanye ze-BB386 EVO. I-chainring yi-aluminium stamping ye-AL7075 kwaye ifumaneka kwiindidi ezahlukeneyo zezantya ezili-10, ezili-11 kunye ne-12 ukuze ilingane nee-drivetrains zeShimano, SRAM kunye ne-FSA, nangona i-FSA ithi ilungiselelwe izantya ezili-11 kunye neli-12.
Ubude be-crank buyahluka ukusuka kwi-145mm ukuya kwi-175mm, kunye nokuxhuma kwe-5mm ukongeza kwi-167.5mm kunye ne-172.5mm. Imnyama ekhazimlisiweyo kwaye inobunzima obufunwayo be-793 grams kwisimo se-46/30, 170mm.
Inkqubo yokulinganisa amandla yinto yamazwe ngamazwe, isebenzisa ii-Japanese strain gauges, ezilinganiswe zii-German torque transducers. Inika ibhalansi echanekileyo yasekhohlo/ekunene, iyahambelana neZwift ngeBLE 5.0, inothumelo lwe-ANT, ayinamanzi kwi-IPX7, kwaye inokubuyisela ubushushu ngokuzenzekelayo. Imitha yamandla inobomi bebhetri obuziiyure ezingama-450 isebenzisa iseli enye ye-CR2450 coin kwaye kuthiwa ichanekile ukuya kuthi ga kwi-+/- 1%. Ixabiso elilindelekileyo lokuthengisa konke oku li-385 euros kuphela.
Inkqubo entsha ye-FSA okanye i-E-System yimoto yokuncedisa umbane engasemva enamandla apheleleyo angama-504wH, kunye neyunithi yokulawula ibhayisekile edibeneyo kunye ne-app yefowuni. Ijolise ekuguquguqukeni nasekudibaneni, ibhetri ye-252Wh ye-FSA yenzelwe ukufakwa kwi-downtube, kwaye ibhetri eyongezelelweyo ye-252Wh ingafakwa kwikheyiji yebhotile ukuze iphindwe kabini. Iqhosha letyhubhu ephezulu lilawula inkqubo, kwaye i-port yokutshaja ikwindawo engaphezulu kwendlu esezantsi.
Ibhetri isebenzisa injini enamavili angama-43Nm, ekhethwe yiFSA ngenxa yokukwazi kwayo ukungena phantse kuyo nayiphi na ifreyimu, nokuba ingakanani na. Inobunzima obuyi-2.4kg kwaye kuthiwa ine-friction ephantsi kakhulu kwisantya esingaphezulu kwe-25km/h. Kukho i-torque sensor edibeneyo ephendula ngokukhawuleza, i-remote dealer diagnostics, kwaye iFSA ithi ayingeni manzi kakuhle, ihlala ixesha elide kwaye kulula ukuyilungisa. Kukho amanqanaba amahlanu oncedo, kunye ne-app yeFSA ehambelana nezixhobo ze-iOS kunye ne-Android ezivumela abakhweli ukuba barekhode idatha yabo yohambo, babonise imeko yebhetri kwaye babonise i-GPS navigation turn-by-turn.
Ngesantya esingaphezulu kwe-25 km/h (32 km/h e-US), ii-hub motors ziyacima, nto leyo evumela umkhweli ukuba aqhubeke nokupeda ngesantya esincinci, nto leyo enika uvakalelo lwendalo lokukhwela. I-E-System ye-FSA ikwahambelana ne-Garmin's E-bike Remote, ekwaziyo ukusebenzisa imisebenzi yokuncedisa ibhayisekile yakho ukude, kunye neGarmin Edge yakho, kwaye inokuba lukhetho lwesithathu lolunye uqhagamshelo lwe-ANT+.
