Pamusoro pematambudziko ekugadzirisa nekumisikidzwa, takagamuchirawo mibvunzo yakawanda inonetsa pamusoro pe geometry yefuremu yebhasikoro remakomo. Munhu anoshamisika kuti chiyero chimwe nechimwe chakakosha sei, kuti chinokanganisa sei hunhu hwebhasikoro, uye kuti chinoshanda sei nezvimwe zvinhu zve geometry yebhasikoro uye marongerwo esuspension. Tichatarisa zvakadzama mamwe ematanho akakosha ekuyera geometry kuti tinzwisise vatasvi vatsva—kutanga nebhuraketi repasi. Hazvigoneki kufukidza zvese zvine chekuita nekuyera furemu imwe chete kunokanganisa sei kutasva bhasikoro, saka tichaita zvese zvatinogona kuti tisvike pazvinhu zvakakosha zvinokanganisa mabhasikoro mazhinji.
Kureba kwebhureki repasi ndiko kuyerwa kwakamira kubva pasi kusvika pakati peBB yebhasikoro kana suspension yareba zvakakwana. Chimwe chiyero, BB drop, kuyerwa kwakamira kubva pamutsetse wakatwasuka uchienda pakati pehub yebhasikoro kusvika pamutsetse wakafanana uri pakati peBB. Kuyerwa uku kuviri kunokosha nenzira dzakasiyana pakutarisa bhasikoro uye pakuona kuti rinofamba sei.
Kazhinji kudzika kweBB ndiko kunoshandiswa nevatasvi kuona kuti vanganzwa sei "mu" uye "vachishandisa" bhasikoro. Kudonha kweBB kwakawedzerwa kunowanzoita kuti mutasvi ave pasi uye ane chivimbo anonzwa sekunge akagara pafuremu pane kuritasva. BB inodonha pakati pema axles inowanzonzwa zviri nani pane BB yakareba kana ichityaira ichitenderera uye ine tsvina yakasviba. Kuyera uku kunowanzo gadziriswa uye hakukanganisirwi nehukuru hwakasiyana hwematayi kana mavhiri. Zvisinei, ma flip chips anowanzo shandura imwe yekuchinja kwejometri. Mafuremu mazhinji ane flip chip anogona kusimudza kana kudzikisa BB yavo ne5-6mm, pamwe chete nemamwe ma angles uye zviyero zvechip. Zvichienderana nenzira yako nezvaunofarira, izvi zvinogona kushandura bhasikoro kuitira kuti imwe nzvimbo ishande pakati penzira, nepo imwe yakakodzera zviri nani kune imwe nzvimbo yakasiyana.
Kureba kweBB kubva pasi pesango kunosiyana-siyana, neflip chip ichifamba ichikwira nekudzika, kushanduka kwehupamhi hwetayi, kushanduka kwehurefu hweforogo kubva paaxle kuenda kukorona, musanganiswa wemavhiri, uye chero kumwe kufambisa kwechimwe kana zvese izvi. Tarisa hukama hweaxle yako nehutsvina. Kureba kweBB kunowanzo kuve kwemunhu, vamwe vatyairi vachisarudza kukwenya mapedals pamatombo vachinzi vanonzwa kutasva, nepo vamwe vachida transmission yakakwira, yakachengeteka kubva panjodzi.
Zvinhu zvidiki zvinogona kuchinja hurefu hweBB, zvichiita shanduko huru pamabatiro anoita bhasikoro. Semuenzaniso, forogo yeFox 38 ye170mm x 29in ine chiyero chekorona che583.7mm, nepo saizi imwe chete ichireba 586mm. Mamwe maforogo ese ari pamusika akasiyana saizi uye anopa bhasikoro kunaka kwakasiyana.
Nebhasikoro ripi zvaro rinokwevera pasi, nzvimbo yetsoka dzako nemaoko ako inonyanya kukosha nekuti ndiyo chete nzvimbo yaunosangana nayo paunodzika. Pakuenzanisa kukwirira kweBB nekudonha kwemafuremu maviri akasiyana, zvinogona kubatsira kuona kukwirira kwestack maererano nenhamba idzi. Stack chiyero chekutarisa pakati pemutsetse mumwe wakatambanuka uchipinda muBB nemumwe mutsetse wakatambanuka uchipinda nepakati pekuvhurika kwechubhu yepamusoro. Kunyange zvazvo stack ichigona kugadziriswa uchishandisa ma spacers ari pamusoro nepasi pehunde, zvakanaka kutarisa nhamba iyi usati watenga furemu kuti uve nechokwadi chekuti unogona kuwana hurefu hwe handlebar hwaunoda, zvichienzaniswa ne BB drop. Effective yakakodzera zvakanyanya zvaunoda.
Maoko mapfupi ecrank uye ma bash guards zvinopa nzvimbo yakawedzerwa uye kuchengetedzeka kune BB yakaderera, asi unofanirwa kungwarira zvigunwe zvako paunenge uchitsika matombo marefu. Kune vatyairi vane makumbo mapfupi, BB yakaderera inodawo hurefu hwechigaro hupfupi kuti ikwane rwendo rwaunoda rwedropper. Semuenzaniso, bhasikoro guru randinotasva parizvino rine 35mm BB drop rinoita kuti bhasikoro rinzwe zvakanaka nekumhanya kunonoka. Ne crank ye165mm yakaiswa, ndaisakwanisa kuisa 170mm dropper post mufuremu refu re445mm. Pane angangoita 4mm pakati pekora yechigaro nepasi pekora yedropper saka BB yakaderera, zvichikonzera bhubhu refu rechigaro kana bhubhu refu recrank rinondimanikidza kuderedza rwendo rwangu rwedropper kana kutasva Frame diki; hapana chimwe chezvinhu izvi chinonzwika chichifadza. Kune rumwe rutivi, vatyairi varefu vachawana nzvimbo yakawanda yekuisa seatpost nekuda kweBB drop yakawedzerwa uye chubhu yakawanda yechigaro, zvichipa simba ravo rekutenga mukati mefuremu.
Saizi yematairi inzira iri nyore yekugadzirisa kukwirira kweBB uye kugadzirisa zvakanaka kona yemusoro webhasikoro pasina kuvhiyiwa kukuru. Kana bhasikoro rako riine seti yematayi e2.4-inch uye ukaisa forogo yekumashure ye2.35-inch uye 2.6-inch yekumberi, mapedal ari pasi pacho hapana mubvunzo kuti achaita zvakasiyana. Ziva kuti chati yejiyomethri yebhasikoro rako inoyerwa uchifunga nezvetairi repashure, saka unogona kuedza kusanganisa kwakasiyana kuti uvandudze ruzivo rwako rwekutasva.
Izvi ndizvo zvimwe zvezvinhu zvakawanda zvinokanganisa kukwirira kweBB uye zvinogona kukanganisa kukwirira kweBB. Une mumwe munhu waunogona kugovana naye watinogona kubatsirwa naye tese here? Ndokumbirawo uzvinyore pasi mumashoko ari pazasi.
Ndingada kupa maonero akasiyana. Ko kana vanhu vazhinji vachida bhasikoro reBB rakaderera, asi chaizvoizvo nekuda kwekuti ma handlebars akaderera zvakanyanya? Nekuti musiyano wehurefu pakati peBB ne handlebars wakakosha pakubata, uye mukuona kwangu mabhasikoro mazhinji ane chubhu yemusoro ipfupi zvakanyanya (zvichida kana iri hombe) uye inowanzo kutengeswa pasi pehunde kana bhasikoro ratengeswa. Hapana ma spacers akawanda.
Ko danda? Chubhu refu yedhiraivha iri muchubhu pfupi yemusoro inoita kuti igone kuchinjika zvakanyanya. Kuchinja kukwirira kwemubato kunowedzera "stack" pasina kukanganisa kukotama kuri muchubhu yedhiraivha.
Ehe, ndine tsinde re35mm rine 35mm spacers uye tsinde…asi wongororo yangu haisi yekuti ungava sei netsinde refu. Izvi zvinodaro nekuti tsinde dzebhasikoro dzinogona kunge dzakaderera zvakanyanya, vanhu vanofarira BB yakaderera nekuti inowedzera musiyano wehurefu pakati petsinde neBB.
BB inochinja panguva yekumisikidzwa. Mutyairi anoisa sag, izvo zvinogona kuchinja kukwirira kweBB nekudonha. Kureba kweBB kunochinja sezvo suspension inotenderera kuburikidza nekudzvanywa uye kudzokororwa sezvo suspension inokwira, asi kazhinji inokwira pakukwirira kwakaiswa panguva yekumisikidzwa. Ini ndinofunga kuti sag settings dzine simba guru (kukwirira, kudonha) kupfuura matai kana flip chips.
Unotaura chokwadi chekuti kusadzika kune simba guru pakuyera kwese kuri kutaurwa. Tinofanira kushandisa mapoinzi akasimba pakuenzanisa mabhasikoro, uye kusadzika kwemunhu wese kwakasiyana, ndosaka ndichishandisa manhamba ekusadzika. Zvingave zvakanaka dai makambani ese akagovanawo tafura yejometri ine kusadzika kwe20% uye 30%, kunyangwe paine vamwe vatyairi vasina kusadzika kwepamberi nekumashure kwakaenzana.
Musiyano uyu unokonzerwa nekukwirira kweb kana tichienzanisa nepasi nepamusoro pevhiri, kwete pakati pevhiri pakutenderera.
Chero kukosha kwenhamba ye bb drop inyaya inochengetwa zvakanaka iyo iri nyore kunzwisisa kune chero munhu ane ruzivo nemabhasikoro madiki ane mavhiri akadai se bmx, brompton kana moulton.
BB yakaderera hazvirevi chubhu refu rechigaro. Hazvina musoro zvachose. Kunyanya kana uchitaura nezvekugadzirisa kukwirira kweBB uchishandisa matayi nemaforogo nezvimwewo. Chubhu yechigaro ine urefu hwakatarwa pafuremu yakapihwa, uye hapana zvigadziriso zvichatambanudza kana kuderedza chubhu iyoyo yechigaro. Ehe, kana ukapfupisa forogo zvakanyanya, chubhu yechigaro ichadzika uye bharero repamusoro rinoshanda richadzikira zvishoma, zvingave zvakakosha kudzorera chigaro kumashure panjanji, uye ipapo chigaro chinofanira kudzikiswa zvishoma, asi hazvichinje hurefu hwechubhu yechigaro.
Zano rakanaka, ndatenda. Tsananguro yangu inogona kunge yakajeka muchikamu ichocho. Chandinoda kutaura ndechekuti kana mainjiniya wefuremu akadonhedza BB uku achiramba akareba pamusoro pechubhu/kuvhura kwechigaro zvakafanana, chubhu yechigaro icharamba yakareba, izvo zvinogona kukonzera matambudziko ekuti dropper post fit ikwane.
Zvakanaka. Kunyangwe ndisina chokwadi chekuti sei zvichikosha kuchengetedza nzvimbo chaiyo yepamusoro pechubhu yechigaro.
Zvikuru sei, mabhasikoro ekuyedza, mashandisirwo awo anowanzo shandiswa anotangira pa +25 kusvika +120mm BB.
Kutaura chokwadi, yangu imotokari yakagadzirwa ne +25 kuti isvike pa zero nemutyairi aripo. Izvi zvinoitirwa kuzadzisa zvinodiwa, nekuti hapana chakaipa kupfuura kushandisa mari yako yawakashanda nesimba pa suspension inoviga mapedals muvhu kana ikabviswa pa piste.
Panyaya inotevera yekugadzirisa hardtail, ndapedza faira reCAD, kusanganisira peji rekuti “Shall”. Ndiwo mazwi ari paBB.
Ndingade kuona kuyerwa kwemvura chaiyo kubva kune vanotasva mabhasikoro vari mu sag. Simba rangu remuchina riri pakati pe -65 ne -75 zvichienderana nenzvimbo ye eccentric. Ndinodzikisa rangu pasi uye rinobata mutsetse zviri nani mumakona uye ndinonzwa ndakadyarwa zvakanyanya muuswa hurefu.
Zvisirizvo, zvese ndezvechokwadi. Kudonha kweBB kunoyerwa kana tichienzanisa nekudonha kwemotokari, saizi yevhiri haichinje izvi, kunyangwe kureba kweforogo kuchichinja. Kureba kweBB kunoyerwa kubva pasi uye kunokwira kana kudonha kana saizi yetayi ichichinja. Ndosaka mabhasikoro makuru ane mavhiri achiwanzova nekudonha kweBB kwakawanda, saka kureba kwawo kweBB kwakafanana nemabhasikoro madiki ane mavhiri.
