Kodi mumatani ngati mafakitale a njinga sangathe kupanga magawo omwe amakwaniritsa zosowa zanu? Ngati ndinu katswiri wopanga komanso wodziwa za mpweya wa aum Town Paul Townsend, mupanga zopangira zanu ndikubera zida zamagetsi zotsutsana.
Paul adanenapo za magwiridwe antchito aukadaulo wamsewu (okhala ndi mabuleki ampweya wama hydraulic) ndi chithunzi chake chapadera cha SRAM-Shimano, tiyenera kuphunzira zambiri.
Poyambira kumayambiriro kwa 2016, msika wamagulu amisewu udawoneka mosiyana kwambiri ndi pano. Shimano sanayambebe kupanga chimbale chake cha Dura-Ace R9170 ndi Di2 combo kit (zosagwiritsa ntchito R875 zisangalalo ndi mabuleki ofananira ndi njira zokhazokha zama hydraulic / Di2), ndipo Red eTap HRD ya SRAM idakali miyezi ingapo.
Paul ankafuna kugwiritsa ntchito mabuleki amphepete mwa hydraulic panjinga yake yapamsewu, koma sanakhutire ndi oyimitsa Magura.
Ndodo ya SRAM yokhala ndi hydraulic rim brake ili ndi kuchotsera zambiri. Ndiwokonda bokosi la gear la Shimano Di2, chifukwa chake adaganiza zophatikiza awiriwa kukhala mashup apadera a DIY.
Izi zimaphatikizapo kusunthira cholembera chomenyera batani ndi batani losinthana ndi zida zamagetsi zokhudzana nazo kuchokera pagawo la zisangalalo za Di2 kupita ku thupi la SRAM hydraulic road joystick.
Makina amadzimadzi a SRAM sanasinthe, koma amagwiritsidwa ntchito ndi masamba a Shimano lever, ndikusunthira kwamagiya kwathunthu kutengera Di2.
Ndidafunsa Paul mafunso kuti ndidziwe zambiri zakukhazikika kwake: momwe amagwirira ntchito, luso lake laukadaulo, ndi zomwe zikutsatira. Yankho la Paulo lidasinthidwa kwakutali ndi kuwunikira.
Tisanapitilire, tikuyenera kunena kuti kusintha mabraketi mwanjira iliyonse kungavulaze kwambiri, ndipo sitikulimbikitsani kuti muchite izi. Kusintha kwa zigawo zikuluzikulu nthawi zambiri kumayambitsanso chitsimikizo cha wopanga.
Kuyambira zaka za m'ma 1980, ndakhala ndikwera njinga pomwe ndimaphunzira zamakina ku Coventry Poly University. Panthawiyo ndinali ndi Topanga Sidewinder ndi njinga yamapiri ya Mick Ives.
Ndakhala ndikugwira ntchito yopanga njinga ndi makonda, ndipo ndakhala wopanga mapulani komanso katswiri waziphuphu kwa nthawi yayitali. Ndasintha magalimoto ndi njinga kwa zaka zambiri.
Ndinali ndi Canyon Ultimate mu 2013 ndipo nthawi zonse ndimakonda ukadaulo, kotero choyambirira ndidachiyika ndi gulu lakunja la Shimano Ultegra 6770 Di2.
Kenako, ndidakweza mabuleki ndikuyesera mabuleki ampira a Magura RT6. Kunena zowona, zinali zovuta, ndipo zinali zovuta kukhazikitsa ndi kukhazikitsa.
Ndapanga chowongolera chowongolera cha njinga yamoto yanga yakunja ndi kuyika chilinganizo cha Formula RR chonyamula pa iyo ndikusintha kwa Di2. Zinkagwira ntchito bwino, koma kuzungulira nthawi ino, mtengo wa mabuleki amiyala yama SRAM HydroR ndi levers pa Planet-X anali otsika kwambiri.
Nditaphunzira momwe magawo a SRAM amagwirizanira palimodzi ndikudziwa malo omwe amafunikira gawo la Di2, ndidagula chophimbira cha HydroR $ 100. Pambuyo pake, ndidagulanso ma seti ena anayi, mnzanga komanso munthu ku United States.
M'mbuyomu, ndidapanganso mabuleki amtundu wa Gravity Research Pipe Dream-V pama njinga zamoto zanga panjira, kenako ndikupanga mashup a njinga zina.
Chifukwa chake, malingaliro athu ndi akuti: mabuleki amadzimadzi amadzimadzi amakhudza kwambiri komanso amathandizira pang'ono. Maguras ndiopweteka komanso amanyazi, chifukwa chake ngati ndikufuna kukonza njinga yamsewu ndimabuleki oyendera ma hydraulic, nditha kusankha SRAM, koma ndimakonda Di2.
Kodi ndizovuta bwanji kuphatikiza ziwirizi? Pambuyo pochotsa makina osinthira liwiro, pali bowo lalikulu mthupi la ndodo ya SRAM, chifukwa chake yankho lake ndi ili: ndilosavuta.
Ndidagula zida zina zachiwiri za 6770 Di2. Chifukwa 11-liwiro Ultegra 6870 Di2 ndi chinthu chatsopano, anthu ambiri molakwika adagulitsa 6770 gear lever kuti akweze [zolakwika chifukwa 6770 itha kugwiritsidwa ntchito ndi dera la 6870 derailleur]. Ndikuganiza kuti ndagula ndalama pafupifupi $ 50.
Kukhazikitsa kwanga kumagwiritsa ntchito bowo lomwe lidalipo mu chikwangwani cha Di2, ndipo limakankhira magawo azitsulo ndi pulasitiki othamangitsa (3D osindikizidwa) a choyambirira cha Di2 chobowoleza pa silinda ya brake, kotero kuti kulimba sikudzakhala kwakukulu. funso limodzi.
Ndinadula gawo lowonjezera kuchokera pamwamba pa chogwirizira cha 6770 Di2, ndikuchikonza chimakanika, kenako ndikulumata ku gawo la sintered prototyping nayiloni.
Ndidayesanso dzenje kuti dzenjelo likhale losalala komanso kukula koyenera. Ndi penti pang'ono, kapena Shimano wobiriwira wobiriwira wa msomali pano, ndakonzeka kusonkhanitsa zonse.
Makonzedwewa sagwiritsa ntchito kasupe wobwezeretsa ndodo kapena E-clip kuti akonze shaft, kotero kuti shaft imabowola ndikugwiridwa kuti ipezeko chopukutira chomwe mutu wake ndi wokulirapo kuposa pini ya pivot. Thupi la lever likangomira pang'ono, mutuwo umatuluka.
Kasupe wobwerera mozungulira amaphatikizidwapo pa shaft master cylinder shaft kuti ipereke mphamvu kwa wobwezeretsayo.
Pambuyo pake, kusintha kokha komwe ndidapanga ndikuwonjezera kachigawo kakang'ono ka O-mphete ku cholembera chakale cha E-clamp cha pivot popewa kuti mabatani a mabuleki asagwedezeke pang'ono.
Chingwe cha Di2 chimafikira poyambira pansi pamunsi pamutu wapulasitiki wosindikizidwa wa 3D wa lever yodziyimitsa, chifukwa chake imakonzedwa ndipo siyimata kapena kutayika.
Pambuyo pochotsa njira zonse zosunthira, njira yokhayo yosinthira magawo a SRAM ndikuyika ma grooves kuti ayike chingwe cha Di2. Module ya Di2 imakonzedwa ndi chidutswa cha thovu kumbuyo kwakumbuyo.
Ndidayendetsanso makina osinthana a sprint, ndikulumikiza chosinthira chakale cha Dura-Ace 7970 Di2 kuchokera pa SW-R600 switch switch ku switch yamagetsi, ndikusintha konse kulumikizidwa ndi ndodo yakumanzere. Chingwecho chidakulitsidwa kuti chikhale ndi njira yolumikizira bwino, ndipo pomwe ndimayendetsa Canyon clone integrated lever handle setup, bokosi la Junction'A'Di2 mu shaft linali mmenemo.
Mabuleki ali ndi zovekera za titaniyamu ndi mabuleki oyimilira opepuka. Amakonzedwa pazithunzi 52 cm. Kulemera konse kwa matayala akutsogolo ndi 375g, kulemera konse kwa magudumu kumbuyo ndi 390g, ndipo kulemera konse kwa magudumu kumbuyo kuli 390g.
Inde, ndikufuna kunena kuti zinali bwino. Ndinagulitsa seti kwa munthu wina ku Hong Kong, amenenso adanditumizira SRAM Red ndi Dura-Ace kuti apange mashup awa.
Ndinagulitsa zida zina kwa munthu wina ku Australia kuti azigwiritsa ntchito pa njinga yake ya TT, ndikugulitsa gawo limodzi mwa magawo atatu kwa munthu ku United States, kuti ndikwanitse kulipira zonse zomwe ndawononga.
Ngati ndilipira mtengo wokwanira pazonsezi, zitha kukhala pachiwopsezo chachikulu. Kuphatikiza apo, nthawi zonse ndimatha kubweza magawo a SRAM kuzinthu zosintha popanda zovuta.
Mwinanso ndidzamupatsa wobwerekerayo kasupe wobwerera wamphamvu. Ndikufuna loko yolumikizira kuti ndiyimitse kusintha kwakomwe ndimayenda mukamayendetsa, chifukwa ndidamasula chosinthira mabuleki ndikudula cholumikizira choyambirira.
Inde, ndikupanga kukwera kwatsopano kwamiyala ndi ma sprint ma gear, ndipo ndikufunafuna njira ina momwe chiwongolero chakutsogolo chizikhala chopangira chothandizira, monga zikuluzikulu zala pa Campagnolo gear lever.
Lingaliro loyambirira linali lakumanja chakumanja ndi lamanzere lamanzere, ndipo ndikuyesabe kugwiritsa ntchito tsamba lazitsulo.
Nditha kumamatira pazitsulo zosanjikiza za SRAM kapena kugwiritsa ntchito Campagnolo, ndikusunga mabatani a SRAM kumbuyo kwa ma gearbox kumbuyo ndi ma levers atsopano pa gearbox yoyang'ana kutsogolo.
Izi zikutanthauza kuti sipadzakhala kusokonekera ngakhale mutavala magolovesi, omwe atha kukhala ovuta m'nyengo yozizira nthawi yayitali ya Shimano.
Zikomo kwambiri Paul poyankha funso langa ndikupereka zithunzi. Kuti mumve zambiri za iye, chonde mutsatireni pa Flickr ndi Instagram, kapena werengani zolemba zake pansi pa dzina la motorapido pagulu la Weight Weenies.
Matthew Allen (yemwe kale anali Allen) ndimakina waluso komanso wodziwa ukadaulo wa njinga. Amayamikira kapangidwe kothandiza komanso kanzeru. Poyamba anali Louis, ankakonda njinga ndi zida zilizonse zamizeremizere. Kwa zaka zambiri, wayesa zinthu zingapo za BikeRadar, cycling Plus, ndi zina zambiri. Kwa nthawi yayitali, mtima wa Matthew udali wa Scott Addict, koma pano akusangalala ndi Specialised's sublime Roubaix Expert ndipo ali paubwenzi wapamtima ndi Giant Trance e-MTB. Ndi wamtali 174 cm ndipo amalemera 53 kg. Zikuwoneka kuti ayenera kukhala bwino kuposa kukwera njinga, ndipo akukhutira.
Mukalowa zambiri, mumavomereza zomwe BikeRadar akufuna komanso zinsinsi. Mutha kulembetsa nthawi iliyonse.
