Specialized anasiya kapangidwe kawo ka nthawi zonse n’kusankha mpando wokhala ndi flex-pivot.
Umembala wakunja umalipidwa pachaka. Kulembetsa kosindikizidwa kumapezeka kwa anthu okhala ku US okha. Mutha kuletsa umembala wanu nthawi iliyonse, koma sipadzakhala kubwezeredwa ndalama zomwe mwalipira. Mukaletsa, mudzakhala ndi mwayi wolowa umembala wanu mpaka kumapeto kwa chaka cholipira. Zambiri
Nthawi zina, zinthu zatsopano zomwe zachitika posachedwapa mumakampani opanga njinga zimaoneka kuti zikuwonjezera zovuta kuposa momwe zilili. Koma si nkhani zoipa zonse. Palinso malingaliro abwino opangitsa njinga kukhala yosavuta komanso yabwino.
Nthawi zina kapangidwe kabwino kamakhala kofunsa zomwe simukufuna poyerekeza ndi kapangidwe kovuta kwambiri ka suspension kapena zida zamagetsi zowonjezera. Mwanjira yabwino kwambiri, kuphweka kumatanthauza kupanga njinga kukhala zopepuka, zopanda phokoso, zotsika mtengo, zosavuta kusamalira komanso zodalirika. Koma osati zokhazo. Yankho losavuta lilinso ndi kukongola ndi luso.
Kusinthaku kunasiya nsanja yopachikidwayo ya Spur m'malo mwa njira yothandizira yosavuta.
Pali chifukwa chake pafupifupi njinga iliyonse ya XC tsopano ili ndi "pivot yosinthasintha" m'malo mwa pivot yachikhalidwe yokhala ndi ma bearing kapena bushings. Ma flex pivots ndi opepuka, amachotsa zigawo zambiri zazing'ono (ma bearing, mabolts, ma washers...) ndi kukonza. Ngakhale ma bearing amafunika kusinthidwa nyengo iliyonse, ma flex pivots opangidwa mosamala adzakhala ndi moyo wa chimango. Ma flex omwe ali kumbuyo kwa chimango, kaya pa mipando kapena ma chainstays, nthawi zambiri amawona madigiri ochepa ozungulira paulendo wa suspension. Izi zikutanthauza kuti ma bearing amatha kusweka ndikutha msanga, pomwe ziwalo zosinthika zopangidwa ndi kaboni, chitsulo kapena aluminiyamu zimatha kunyamula mosavuta mayendedwe awa popanda kutopa. Tsopano nthawi zambiri amapezeka pa njinga zokhala ndi maulendo okwana 120mm kapena kuchepera, koma ma flex pivots oyenda nthawi yayitali apangidwa, ndipo ndikuganiza kuti tidzawona zambiri pamene ukadaulo wopanga ukukwera.
Kwa okwera njinga zamapiri okonda kwambiri, ubwino wa imodzi ndi imodzi ukhoza kukhala woonekeratu kwambiri moti umadziwonekera wokha. Amatithandiza kuchotsa ma front derailleurs, ma front derailleurs, zingwe ndi (nthawi zambiri) ma chain guides, pomwe amaperekabe ma gear osiyanasiyana. Koma kwa okwera atsopano, kuphweka kwa shifter imodzi ndikopindulitsa kwambiri. Sikuti ndi zosavuta kuyika ndi kusamalira zokha, komanso ndizosavuta kukwera chifukwa mumangofunika kuganizira za shifter imodzi ndi ma gear ogawidwa nthawi zonse.
Ngakhale kuti si zatsopano kwenikweni, tsopano mutha kugula ma hardtails oyambira omwe ali ndi ma drivetrain abwino a single-ring. Ichi ndi chinthu chabwino kwambiri kwa munthu amene wangoyamba kumene masewerawa.
Ndikutsimikiza kuti padzakhala kutsutsidwa kwakukulu poteteza pivot imodzi, koma apa tikupita. Pali kutsutsidwa kuwiri kwa njinga za single-pivot. Choyamba chikugwirizana ndi kuletsa mabuleki ndipo chimagwiranso ntchito pa njinga za single-pivot zoyendetsedwa ndi link komanso njinga zenizeni za single-pivot.
Chifukwa chachikulu chogwiritsira ntchito kapangidwe ka pivot imodzi yolumikizidwa ndi ulalo (yomwe ndi kapangidwe kofala kwambiri masiku ano) ndikuchepetsa ndikusintha mawonekedwe a anti-rise, omwe ndi mphamvu ya braking pa suspension. Izi zikutanthauza kuti suspension imayenda momasuka pamwamba pa ma bumps ikagunda. Koma kwenikweni, si nkhani yayikulu. Ndipotu, ma values ​​apamwamba a anti-rise a single pivots amawathandiza kuti asagwere pansi pa brake, zomwe zimapangitsa kuti azikhala olimba kwambiri akagunda, ndipo ndikuganiza kuti zotsatira zake zimakhala zoonekeratu. Ndikoyenera kunena kuti kwa zaka zambiri, njinga zamoto za single-axle zochokera kumakampani monga apambana World Cups ndi mipikisano yambiri.
Kutsutsa kwachiwiri kumagwira ntchito pa njinga zenizeni za single-axle, komwe kugwedezeka kumayikidwa mwachindunji pa swingarm. Nthawi zambiri sakhala ndi kupita patsogolo kwa chimango, zomwe zikutanthauza kuti kupita patsogolo kulikonse kapena "kukwera" kwa masika kuyenera kuchokera ku kugwedezeka. Ndi kulumikizana kopita patsogolo, mphamvu yonyowa imawonjezekanso kumapeto kwa kugwedezeka, zomwe zimathandizanso kupewa kutsika pansi.
Choyamba, ndikofunikira kunena kuti mapangidwe ena ovuta kwambiri, monga Specialized's, si apamwamba kwambiri kuposa ma pivots ena amodzi. Komanso, ndi ma air shocks amakono, njira yosinthira ma springi okhala ndi ma volume shims ndi yovuta. Kutengera ndi amene mumafunsa, kuchuluka kwa damping komwe kumadalira sitiroko kuchokera ku ma linkages opita patsogolo sikwabwino nthawi zonse. Ichi ndichifukwa chake kupanga njinga yotsika yokhala ndi progressive link yoyendetsera springi (coil) ndi linear link yoyendetsera damper.
Zoonadi, kulumikizana kopita patsogolo kungagwire ntchito bwino kwa anthu ena komanso zinthu zina zododometsa, koma ndi kukhazikitsidwa koyenera kwa zinthu zododometsa, pivot imodzi imagwira ntchito bwino. Mukungofunika kasupe wopita patsogolo komanso/kapena kutsika pang'ono. Ngati simukundikhulupirira, mutha kuwerenga ndemanga zabwino kwambiri za njinga za single-pivot kuchokera kwa oyesa ena apa ndi apa.
Komabe, ndikuganiza kuti kulumikizana kopita patsogolo nthawi zambiri kumakhala bwino poyerekeza ndi momwe zinthu zilili. Koma ndi ma shocks oyenera, ma single pivots amagwira ntchito bwino kwa ife omwe si akatswiri othamanga, ndipo kusinthana kosavuta kwa ma bearing kumapangitsa kuti ikhale chisankho chabwino kwa iwo omwe akuyenda m'matope ambiri.
Pali njira zambiri zovuta zoyesetsera kukulitsa magwiridwe antchito a suspension: maulalo apamwamba, zotengera zotsika mtengo zonyamula shock, zongoyenda zokha. Koma pali njira imodzi yokha yotsimikizika yothandizira njinga kusalaza mabala: kuipatsa kuyenda kowonjezereka kwa suspension.
Kuwonjezera maulendo sikuti kumawonjezera kulemera, mtengo, kapena zovuta, koma kumasintha kwambiri momwe njinga imayamwira bwino zinthu zomwe zimagwedezeka. Ngakhale si aliyense amene amafuna ulendo wokonzedwa bwino, mutha kukwera njinga yanu yamtunda wautali yomwe mumakonda pochepetsa kutsika, kugwiritsa ntchito kutseka, kapena kuwonjezera ma spacer owonjezera voliyumu, koma simungayende nanu ngati njinga yofewa yoyenda pang'ono.
Sindikunena kuti aliyense ayenera kukwera njinga yotsika phiri, koma kupatsa njinga ya fumbi kuyenda kokulirapo kwa 10mm kungakhale kosavuta komanso kothandiza kwambiri pakukonza njira yotsatirira, kugwira, komanso kutonthoza kuposa kapangidwe kovuta kwambiri koyimitsa.
Mofananamo, pali njira zambiri zamakono zowongolera magwiridwe antchito a mabuleki, monga ma rotor opumira mpweya, ma rotor awiri, ma brake pad opindika, ndi ma lever cams. Zambiri mwa izi zimawonjezera mtengo ndipo nthawi zina mavuto. Ma Fin pad nthawi zambiri amanjenjemera, ndipo ma lever cams amatha kukulitsa kusagwirizana kapena kufooka kwa dongosolo la hydraulic.
Mosiyana ndi zimenezi, ma rotor akuluakulu amawonjezera mphamvu, kuziziritsa komanso kusasinthasintha popanda kuwonjezera zovuta. Poyerekeza ndi ma rotor a 200mm, ma rotor a 220mm amawonjezera mphamvu ndi pafupifupi 10% pomwe amaperekanso malo ambiri kuti achotse kutentha. Inde, ndi olemera kwambiri, koma pankhani ya ma rotor, ma disc amalemera pafupifupi magalamu 25 okha, ndipo kulemera kowonjezera kumathandiza kuyamwa kutentha panthawi yotseka kwambiri. Kuti zinthu zikhale zosavuta, mutha kuyesa ma rotor a 220mm ndi ma brake a pot awiri m'malo mwa ma rotor a 200mm ndi ma brake a pot anayi; ma brake a piston awiri ndi osavuta kusamalira ndipo ayenera kufananizidwa ndi kulemera ndi mphamvu.
Sindikufuna kupereka chithunzi cha Luddite. Ndimakonda ukadaulo womwe umapangitsa njinga kugwira ntchito bwino, ngakhale itakhala gawo laling'ono chabe. Ndine wokonda kwambiri ma dropper posts oyenda mtunda wautali, makaseti a 12-speed, ma inserting a matayala, ndi ma air springs amphamvu kwambiri chifukwa amapereka maubwino owoneka bwino. Koma pamene kapangidwe kake kamakhala ndi zigawo zochepa kamagwira ntchito bwino kwambiri m'dziko lenileni, ndimakonda kugwiritsa ntchito njira yosavuta nthawi zonse. Sikuti kungosunga magalamu ochepa kapena mphindi zochepa pa shopu; yankho losavuta komanso lokhutiritsa lingakhalenso laukhondo komanso lokongola kwambiri.
Lowani kuti mupeze nkhani zaposachedwa, nkhani, ndemanga ndi zotsatsa zapadera kuchokera ku Beta ndi mabungwe athu ogwirizana, zomwe zidzatumizidwa ku imelo yanu.
