I-Cyclingnews isekelwa yizithameli. Singathola amakhomishini asebenzisana nathi uma uthenga ngezixhumanisi ezikuwebhusayithi yethu. Yingakho ungasithemba.
Sekudlule iminyaka engaphezu kwemine selokhu i-FSA yethule i-groupset yayo ye-K-Force WE (Wireless Electronic) enama-speed angu-11, futhi kungakapheli neminyaka emibili kusukela inguqulo yayo ye-disc brake. Kodwa namuhla, inkampani imemezela ukuthi izosebenzisa ama-speed angu-12 nge-K-Force WE 12 disc brake groupset. Ngokwemvelo, ifuna ukwakha phezu kwezizukulwane ezedlule futhi incintisane ngqo nama-electronic road bike groupset anama-speed angu-12 avela ku-Big Three – Shimano, SRAM kanye neCampagnolo.
Kodwa akupheleli lapho. Le khithi yakhishwa ngesikhathi esifanayo nenqwaba yemikhiqizo yalo mkhiqizo, ehlanganisa imigwaqo, izintaba, amatshe ayigugu kanye namabhayisikili kagesi.
Njengoba i-FSA ichaza ngokuthi “i-drivetrain ebuyekeziwe,” izingxenye eziningi ze-K-Force WE 12 zifana kakhulu nezingxenye zamanje ze-11-speed, kodwa ngaphezu kokuthuthukela kuma-sprocket angu-12, kunezinye izinguquko zokuklama nokuqeda ukuthuthukisa ukusebenza kanye nobuhle.
Ikhithi ye-WE inama-shifter angenantambo adlulisela imiyalo yokushintsha kumojuli yokulawula ephezu kwe-derailleur engaphambili. Womabili ama-derailleurs axhunywe ngokomzimba ebhethri elifakwe eshubhini lesihlalo, okusho ukuthi ikhithi ayinantambo ngokuphelele, kodwa abaningi bayibiza ngokuthi ayinantambo ngokuphelele.
Ngaphandle kwezithombe ezintsha nezicashile, umzimba we-shift lever, i-kinked brake lever kanye ne-shift button kudlula i-ergonomics ekhona, ehlonishwa kakhulu futhi kubukeka kungashintshile ngaphandle. Kunjalo nangama-disc calipers, kuyilapho i-shifter igcina i-compact master cylinder yayo, ukulungiswa kwebanga lama-compound lever blades, ama-exhaust ports afakwe phezulu kanye ne-CR2032 coin cell wireless transmission esebenza ngebhethri.
Isisindo esishiwoyo se-shifter ngayinye kanye ne-caliper (kufaka phakathi i-brake hose kanye namafutha) singamagremu angu-405, amagremu angu-33 kanye namagremu angu-47 esindayo, ngokulandelana, kunesisindo esishiwoyo senkampani sama-shifter e-WE Disc angama-11-speed kwesobunxele nakwesokudla. Izisindo zangaphambilini zazingenawo ama-brake pad, kodwa izisindo ezinikezwa ama-caliper amasha azikhulumi ngazo.
I-derailleur entsha yangemuva ibonakala ihlukile kunguqulo yejubane eli-11 kuphela ngokuqeda nangesisindo, inezithombe ezintsha eziyimfihlo kanye namagremu angu-24 engeziwe. Isenomthamo omkhulu womthwalo ongamathani angu-32 kanye ne-pulley ye-FSA yokugijima, futhi mhlawumbe ayinayo i-return spring, esebenza njengengalo yerobhothi kunendlela yangemuva yendabuko ye-parallelogram.
I-derailleur engaphambili ihlala ingumqondo wokusebenza, njengoba ithola amasignali angenantambo avela ku-shifter futhi ilawula zonke izinto ezishintshayo zesistimu.
Ifanelana nesithasiselo esijwayelekile esinomshini oqinile, igcina ukulungiswa kwayo okuzenzakalelayo, futhi inesikhathi sokushintsha esingu-70ms. Ngokungafani nomthamo omkhulu we-sprocket wenguqulo enama-speed angu-16, imodeli enama-speed angu-12 inamazinyo angu-16-19. Ngaphandle kwezithombe "ezingu-12" ezingachazwanga kahle, umzimba wayo omude, omkhulu ubukeka ufana, kodwa uhlaka lwensimbi lucwengisisiwe futhi izikulufo ezisobala ngemuva azisabonakali. Isisindo esishiwoyo sehlisiwe kusuka kumagremu angu-162 kuya kumagremu angu-159.
I-FSA ihlanganise i-groupset entsha ye-WE 12-speed ne-crankset yayo ye-K-Force Team Edition BB386 Evo. Ijabulisa kakhulu ngobuhle kunama-crank angaphambilini e-K-Force, enama-crank angenalutho e-3K carbon composite kanye nama-chainring e-CNC AL7075 afakwe ngqo engxenyeni eyodwa.
I-FSA ithi ama-chainring amnyama afakwe i-anodized, afakwe isihlabathi ayahambisana nama-drivetrain e-Shimano, SRAM kanye ne-FSA angu-11- kanye no-12-speed. Ama-axle e-BB386 EVO ayi-alloy enobubanzi obungu-30mm kanye nobubanzi bama-bracket angezansi e-FSA aqinisekisa ukuhambisana okubanzi.
Ubude be-crank obutholakalayo bungu-165mm, 167.5mm, 170mm, 172.5mm kanye no-175mm, kanti ama-chainring atholakala ngokuhlanganiswa okungu-54/40, 50/34, 46/30. Isisindo sendandatho esingu-54/40 esibizwa ngokuthi amagremu angu-544.
Ushintsho olukhulu olubonakalayo kwikhithi ye-K-Force WE ye-FSA yi-sprocket yayo eyengeziwe. I-flywheel isakhiwe nge-cast-piece eyodwa, ephathwa ngokushisa, kanti i-sprocket enkulu kunazo zonke i-electroless nickel plated. I-sprocket encane yi-titanium kanti ikhasethi itholakala ngobukhulu obungu-11-25, 11-28 kanye no-11-32. I-FSA ithi ikhasethi yayo entsha yesivinini esingu-11-32 enesisindo esingu-12 amagremu, elula kakhulu kunekhasethi yangaphambilini yesivinini esingu-11-28 enamagremu angu-257.
I-FSA ichaza uchungechunge lwe-K-Force njengoluthule futhi olusebenza kahle, lunezikhonkwane ezingenalutho, ububanzi obungu-5.6mm kanye nesiphetho esenziwe nge-nickel, futhi kuthiwa lunesisindo esingamagremu angu-250 kanye nezixhumanisi ezingu-116, uma kuqhathaniswa namagremu angu-246 ezixhumanisini ezingu-114 zangaphambilini.
Ama-rotor e-K-Force WE anomklamo we-rotor onezicucu ezimbili one-aluminium carrier eyenziwe ngobumba, indandatho yensimbi engagqwali egayiwe kanye nemiphetho eyindilinga ye-centre lock noma ama-bolt hubs ayisithupha, ububanzi obungu-160mm noma 140mm. Isisindo sawo esishiwoyo sikhuphuke sisuka ku-100g kanye no-120g ku-140mm kanye no-160mm ngokulandelana saya ku-103g kanye no-125g.
Kwenye indawo, ibhethri elingu-1100 mAh elifakwe eshubhu lesihlalo sangaphakathi linika amandla ama-derailleur amabili ngentambo enamathiselwe, futhi kufanele linikeze isikhathi sokusetshenziswa esifanayo noma esithuthukisiwe phakathi kokushaja. Uhlelo lwe-WE lokuqala kwakudingeka luvulwe ngenkinobho ku-derailleur yangaphambili ngaphambi kokusebenzisa, futhi lwangena kwimodi yokulinda ngemva kwesikhathi sokungasebenzi. Ngaphambilini lalishajwa ngokushintsha ikhebula le-derailleur yangaphambili ngeshaja. Nakuba ibhethri kanye nocingo kubonakala kungashintshi, okwamanje akukho lwazi ngale nqubo noma impilo yebhethri elindelekile.
Okunye okumenyezelwe namuhla yimitha yamandla entsha ye-FSA, esekelwe ku-crankset ye-aluminium ye-AL6061/T6 eyenziwe ngobumba olubandayo ene-axles ye-MegaExo 24mm noma ye-BB386 EVO. I-chainring iyi-aluminium stamping ye-AL7075 futhi itholakala ngesivinini esihlukahlukene esingu-10, 11 kanye no-12 ukuze ilingane ne-Shimano, SRAM kanye ne-FSA drivetrains, yize i-FSA ithi ilungiselelwe isivinini esingu-11 kanye no-12.
Ubude be-crank buyahlukahluka kusuka ku-145mm kuya ku-175mm, kanye nokugxuma okungu-5mm ngaphezu kuka-167.5mm no-172.5mm. Imnyama epholishiwe futhi inesisindo esingu-793 amagremu kulungiselelo lwama-46/30, 170mm.
Uhlelo lokulinganisa amandla luyinto yamazwe ngamazwe ngempela, lusebenzisa ama-strain gauge aseJapan, alinganiswe ngama-transducer e-torque aseJalimane. Lunikeza ibhalansi yesobunxele/kwesokudla ebonakalayo, luhambisana neZwift nge-BLE 5.0, lune-ANT transmission, alungeni manzi nge-IPX7, futhi lunesinxephezelo sokushisa okuzenzakalelayo. Imitha yamandla inempilo yebhethri efunwayo yamahora angu-450 isebenzisa iseli elilodwa lezinhlamvu zemali ze-CR2450 futhi kuthiwa linembile ku-+/- 1%. Intengo yokuthengisa elindelekile yakho konke lokhu ingama-euro angu-385 kuphela.
Uhlelo olusha lwe-FSA noma i-E-System luyinjini yokusiza kagesi ye-hub yangemuva enamandla aphelele angu-504wH, kanye neyunithi yokulawula ibhayisikili ehlanganisiwe kanye nohlelo lokusebenza lwe-smartphone. Igxile ekuguquguqukeni nasekuhlanganisweni, ibhethri le-FSA elingu-252Wh lenzelwe ukufakwa kwe-downtube, futhi ibhethri elengeziwe elingu-252Wh lingafakwa ekhejini lamabhodlela ukuze liphindwe kabili ububanzi. Inkinobho yepayipi ephezulu ilawula uhlelo, futhi imbobo yokushaja itholakala ngaphezu kwendlu engezansi ye-bracket.
Ibhethri lisebenzisa injini engu-43Nm in-wheel, i-FSA eyikhethile ngenxa yekhono layo lokungena cishe kunoma yiluphi uhlaka, kungakhathaliseki ukuthi ingakanani. Inesisindo esingu-2.4kg futhi kuthiwa inokungqubuzana okuphansi kakhulu ngesivinini esingaphezu kuka-25km/h. Kukhona inzwa ye-torque ehlanganisiwe ephendula ngokushesha, ukuxilongwa kwabathengisi abakude, futhi i-FSA ithi iyamelana kahle namanzi, ihlala isikhathi eside futhi kulula ukuyinakekela. Kunezigaba ezinhlanu zosizo, kanye nohlelo lokusebenza lwe-FSA oluhambisana namadivayisi e-iOS ne-Android oluvumela abagibeli ukuthi baqophe idatha yabo yokugibela, babonise isimo sebhethri futhi babonise ukuzulazula kwe-GPS ngokujika.
Ngesivinini esingaphezu kwamakhilomitha angu-25 ngehora (32 km/h e-US), ama-hub motors ayavalwa, okuvumela umgibeli ukuthi aqhubeke nokupheda ngokunciphisa ukungqubuzana okusele, okunikeza umuzwa wokugibela wemvelo. I-E-System ye-FSA nayo iyahambisana ne-Garmin's E-bike Remote, engasebenzisa imisebenzi yokusiza ibhayisikili lakho ukude, kanye ne-Garmin Edge yakho, futhi ingaba inketho yesithathu yolunye uxhumano lwe-ANT+.
