njinga yamoto
Ili pafupi kulowa m'nyengo yophukira, ndipo ndizabwino kukwera m'nkhalango!
Koma ngati tingakumane ndi zovuta monga "kulumidwa ndi njoka", kuboola, ndi mpweya, izi zichepetsa kwambiri kukwera kwathu kosangalatsa. Tayala likaphulika, kuphatikiza pachitetezo chaumwini, zimayambitsanso mphonje.
Ngati mutha kukhazikitsa tayala lomwe likukuyenereranitu, mudzatha kuboola dzenje mowirikiza, ngati kuti mukuyenda pansi!
Kodi tayala labwino ndi lotani?
Lero ndikugawana nanu kupsyinjika kwa matayala a njinga zamapiri kuti athane ndi mafunso ena m'mitima ya okwera
Matayala samadzaza nthawi zonse. Ngati mpweya ndiwokwera kwambiri, zimapangitsa kuti kukwera kumveke kovuta komanso kosasangalatsa, kapena kupangitsa kuti chubu lamkati likhale losavomerezeka ndikuboola tayala. Kuthamanga kwa tayala kumakhala kotsika kwambiri, kumapangitsa kukwera kwake kukhala kotopetsa kwambiri. Kodi tayala labwino ndi lotani? Kodi mukudziwa zomwe zimakhudza kukakamizidwa kwa matayala?
Kulemera kwake
Anthu nthawi zonse amakhala nkhani ya njinga. Kaya tayala limagwira bwino limayenderana kwambiri ndi kulemera kwa okwera. Mwachitsanzo, wokwera amene amalemera 60kg ndikugwiritsa ntchito tayala lamapiri la 26 × 2.0 atha kupeza kuti kuthamanga kwa tayala la 40psi ndi kovuta kwambiri ndipo sikumgwira. M'malo mwake, ngati wokwera 85kg akukwera, kuthamanga kwa tayala kumakhala kotsika kwambiri.
Wokwera wokwera pamafunika tayala lalikulu.
Turo voliyumu
Vuto la tayala ndichinthu chofunikira kwambiri pakukakamiza matayala, ndipo limatsimikizira magwiridwe antchito a tayalalo. Mwachitsanzo, 40 psi pa 700 × 20c (circumference of 2114mm) tayala lamsewu limadzimva bwino kwambiri, koma matayala a m'mapiri a 27.5 × 2.3 azikhala ofewa kwambiri, msewu wamavuto ungawononge tayalalo.
Mapepala oyendetsa matayala am'mapiri nthawi zambiri amadziwika kuti amakhala ndi matayala ambiri, omwe nthawi zambiri amakhala 65 psi.
Mtundu wokwera
Pamene okwera ndege amachoka pa kakhalidwe koyera ka "Mountain Horse Party" kupita ku msewu wa nkhalango wa XC komanso kukwera kwa njira yakukwera kwa DH. Kukwera kwanu kumatsimikizira ngati msewu womwe mukuyenda ndi nthaka yofewa kapena thanthwe, ndipo misewu ina imafunikiranso matayala osiyanasiyana kuti azolowere madera osiyanasiyana.
Kapangidwe ka matayala
Monga cholinga chokwera mphamvu yonyamula katundu-mtundu wa tayalalo ndi womwe udzagwiritse ntchito bwino. Mtengo wa TPI (kachulukidwe ka nyama ya tayala) wa tayala umatsimikizira kuti muyenera kugwiritsa ntchito kuthamanga kwapamwamba kapena kutsika kwa matayala kuti muzolowere matayala osiyanasiyana. Mtengo wa TPI. Nthawi zambiri matayala okwera kwambiri amakhala ocheperako kuposa matayala a TPI otsika, koma matayala opanda Tubeless (opanda chiyembekezo) kapena matayala okonzekera Tubeless (quasi-tubeless) amakhala ndi matayala ochepa. Chifukwa chake, ndikofunikira kuti okwera ndege apeze tayala loyenera molingana ndi kapangidwe ka matayala osiyanasiyana akakwera.
Poyerekeza mtengo wa TPI wa njinga zamapiri, mutha kuwona kuuma kwa nyama ya mphira.
Matayala ampweya wama tayala amapiri a njinga zamapiri nthawi zambiri amakhala pakati pa 30-65psi, ndipo valavu yake yodziyimira payokha ya Presta ndi kuthamanga kotsika ndi chimodzi mwazinthu zake zazikulu.
Mutamvetsetsa zomwe zimakhudza kuthamanga kwa tayala, kudzakhala kosavuta kuyikapo kupanikizika kwanu. Momwe mungayambitsire kuthamanga matayala njinga yamapiri molondola?
Pokwera phiri, kukhathamira kwa matayala nthawi zambiri kumapangitsa kuti tayala ligundike, ndipo ngati tayala lachepa kwambiri, ndikosavuta "kuluma njoka" ndikuboola tayalalo. Kwenikweni, matayala ambiri amtundu wa XC ochepera pamsewu ndi ocheperako kuposa matayala a AM kapena DH panjira. Chifukwa chake, tikulimbikitsidwa kukhazikitsa kuthamanga kwa tayala pakati pa 40-60psi. Ngati ndi galimoto yofewa ya mchira yokhala ndi zoyatsira kawiri, imatha kufikira 50-60 psi. Panjinga zomwe zimayimitsidwa kamodzi, 45 psi imagwiritsidwa ntchito ngati mtengo wapakatikati, kenako imakwezedwa kapena kutsika kutengera zinthu monga nthaka youma ndi yonyowa, momwe zinthu zilili komanso mtundu wa nthaka.
Nthawi zambiri amalimbikitsidwa kuti achepetse kuthamanga kwa 1-5 psi m'malo ofewa, amchenga, omwe amatha kuyendetsa bwino matayala. M'malo ovuta komanso amiyala ofanana ndi DH mosalekeza kutsika kutsika, kuthamanga kwa matayala kumatha kukwera pang'ono (kuphatikiza 5psi), komwe kumatha kuwonjezera kutha kwa tayala ndikuletsa "kulumidwa ndi njoka" kuti zisachitike.
Kuluma kwa njoka: Kukwera kumapiri komwe kuli miyala yambiri, ngati kupanikizika kwa matayala sikukwanira, kumapangitsa chubu lamkati kugundana ndi nthaka, kenako ndikuboola kuchokera mu dzenje laling'ono.
Pakakhala tayala lamapiri panjinga yamapiri, tifunikirabe kudalira kuwonjezeka kwa chidziwitso kuti tikwaniritse matayalawo. Pogwira ntchito bwino, ndikofunikira kugwiritsa ntchito barometer kuyeza kuthamanga kwa matayala momwe mungathere, m'malo mongomuyesa ndi zala.
M'mipikisano yambiri yamapiri, tiona kuti madalaivala ambiri amakhala ndi matayala osiyanasiyana kutsogolo ndi kumbuyo. Chifukwa magudumu akumbuyo amayang'anitsitsa kukwiya ndipo mawilo akumbuyo amakonda kudutsa, timalimbikitsa kuti kuthamanga kwamatayala kutsogolo kukhale kotsika 2-5psi kuposa komwe kumayambira kumbuyo.
Tikukhulupirira kuti kudziwa za matayala njinga yamapiri kumatha kuyankha mafunso anu ena!
Hotbike akugulitsa njinga zamagetsi, ngati mukufuna, chonde dinani njinga yamoto tsamba lovomerezeka kuti muwone
