Kodi ndinu oyenda pawokha? Kapena wokwerapo? Kapena woyendetsa njinga nthawi zina? Mutakumana ndi njira zosiyanasiyana zokukwera, muyenera kuphunzira kusankha mitundu yosiyanasiyana ya njinga. Komanso kusankha matayala oyenera ndi umodzi wa maluso omwe mungafune. Kuphatikiza podziwa kukula kwa matayala omwe galimoto yanu imafunikira, pali mitundu yambiri yamatayala.

Ngakhale mutakhala dalaivala wamtundu wanji, ndikofunikira kuti musatope kwambiri. Matayala akunja amaluka kumathandizira kuti matayala aphulike mukakwera. Onani momwe matayala akuvalira panthawi yake ndikusintha tayala lakunja lomwe likuvala kwambiri kumakuthandizani bwino luso lanu.

Mafotokozedwe a matayala - m'mimba mwake ndi m'lifupi

Kodi ndikudziwa bwanji matayala anu? Zosavuta kwambiri. Yang'anani khoma lam'mbali la tayala.

 

Bicycle yam'mapiri: kunja kwa tayala la njinga yamapiri, muwona mawu a 27.5 × 2.0, omwe akuwonetsa kutalika kwa tayalalo (mainchesi 2.0) ndi kukula kwa gudumu (27.5). Nthawi zambiri, matayala a njinga yamoto yamapiri amakhala pakati pa 1.9 ndi 2.25. Ma scooter ndi njinga zamapiri zamtunda zonse zimakhala ndi matayala omwe ali pakati pa 2.25 ndi 2.4 mulifupi, ndipo ndichachidziwikire, njinga za DH zili ndi matayala omwe ndi mainchesi 2.5 m'lifupi

Bicycle yapamsewu: pa tayala lakunja la njinga yamsewu, mudzawona nambala yosiyana ndi tayala lakunja la njinga yamapiri, monga 700 × 23. Nambala yoyamba (700) imayimira kukula kwa gudumu, lomwe limayeza milimita. Nambala yachiwiri (23) imayimira matayala enieni, komanso mamilimita.

Kupatula kunja kumaphatikizapo 650S, chida chomwe chimapangitsa kuti asinthe ma tayala akutsogolo mwachangu kapena madalaivala ang'ono, ndi 27in, yomwe imagwiritsidwa ntchito kwambiri ndi magalimoto akale.

Mudzawona 700c patayala lakunja lagalimoto yamsewu kwambiri. Kodi c kumapeto kumatanthauza chiyani? M'mbuyomu, muyezo waku France, amagwiritsa ntchito zilembo a, b, ndi c kutolera ma diameters osiyanasiyana amitundu. Masiku ano, malo aliwonse okwera 700 ndi ofanana ndi kutha kwa 700c m'mbuyomu, ndipo mwina mwawonapo 650b, yomwe ndi kukula kofanana ndi njinga yamapiri yamakilomita 27.5-inchi, ndi 650c, yomwe ili ndi yaying'ono yaying'ono mkati mwake kuposa 650b yotuluka, yomwe mungapeze pamayendedwe ena amsewu

Magalimoto ambiri amumsewu tsopano amagwiritsa ntchito matayala 700c, omwe amakhala mulifupi kuyambira 18 mpaka 23 mamilimita. Kwa iwo omwe amakwera ma gareta, ma tayala akunja nthawi zambiri amakhala 25-28mm kutalika kuti akhale okhazikika ndi otonthoza.

Nthawi zambiri, matayala aliwonse 700 masiku ano amakhala ofanana ndi tayala lakale la 700c. Mutha kuwona 650b, yomwe ili yofanana ndi masiku ano a 27.5 "matayala njinga zamapiri, ndi 650c, yomwe ili ndi mkatikati kocheperako pang'ono kuposa matayala a 650b ndipo imatha kupezeka panjinga zingapo zamisewu.

Kuyendetsa njinga yamsewu: njinga yamsewu ili ndi zofananira matayala ammapiri, koma idapangidwa kuti ikhale 700 kukula kuti ikwaniritse chimango.

29ers: Poyerekeza ndi msewu wakunja, tayala lakunja la njinga yamtunda wa 29-inchi yakutali limakhala ndi matalikidwe osiyanasiyana komanso mawonekedwe osiyanasiyana, koma nthawi zambiri limawoneka lofanana ndi tayala wamba lakunja kwa njinga. Lingaliro lakapangidwe ka tayala lakunja la mainchesi 29 ndikuchepetsa kukana kwa msewu waukadaulo ndi msewu wamtali. Chifukwa cha kuchuluka kwa msewu wolumikizana ndi mseu, njinga yamapiri 29-inch ndiyosavuta kuyendetsa galimoto ikamatembenuka ndikukwera.

BMX: m'mimba mwake mwa chubu chakunja nthawi zambiri mumakhala mainchesi 20

Kukula kwa tayala lanu kumadalira kukula kwa galimoto yanu (m'lifupi mwake). Ndi funso losavuta "lakuda kapena loyera" lomwe anthu ambiri samamvetsa. Mosiyana ndi izi, matayala a gawo lina - matayala m'lifupi, pali chidziwitso chochulukirapo. Zinthu zina kukhala zofanana, kusiyana kokha m'lifupi kwa matayala kungapangitse kusiyana kwakukulu pakakwera. Tiyeni tisalowe mu zimenezo kwa mphindi.

Kusankha kosenda

Njira zopondaponda zimatanthauzira bwino, komanso kukokera kwakukulu. Chifukwa chake muyenera kuchita bwino pakati pa kuthamanga ndi kuthamanga.

Matayala osagwiritsidwa ntchito: omwe amapangidwira magalimoto amisewu, magalimoto amzindawu / oyendetsa, ngolo zamagalimoto ndi njinga zamapiri. Kuponderera kosalala kulibe njira iliyonse yopondera, yomwe imatha kubweretsa kukana pang'ono. Malo osalala amapangidwira malo osalala, monga phula, malo oyera komanso opyapyala, zomwe zimapangitsa kuti ulendo wanu ukhale mwachangu komanso kosavuta. Matayala ena opanda tayala ali ndi mabowo m'mbali kuti azitha kugwira bwino potembenuka, makamaka ngati mukuyenda mumsewu wothirira madzi.

Matayala osalala: Poyerekeza matayala osalala, tayala lamtunduwu limapangidwa ndi chipika cha mphira kumbali. Kusunthidwa kosalala pakati kumachepetsa kuyendetsa matayala pomwe kumathandizira kuthamanga. Zovala zoterezi zimagwiritsidwa ntchito pamalo owala panjira.

 

Tayi yopanda mano: matayala osaya mano ali ndi zovuta zotsika komanso zolimba. Kupanga kwamatayala kotereku kumatha kuzolowera mawonekedwe osiyanasiyana a njinga. Ndi imodzi mwa matayala abwino kwambiri oyambira kumene.

Matayala amtundu wa magiya: pali njira zosiyanasiyana pamayendedwe osiyana ndi msewu. Chipingacho chaching'ono chimatha kuchepetsa kukokana ndipo chimakhala choyenera panjira yamsewu. Matayala akuluakulu amakhala ndi mizu yabwinobwino ngati mizu yambiri ili ndi poyambira panjira. Tayi yokhala ndi matayala akuluakulu ndi yabwino kumenya nkhondo, ndipo imakuthandizani kuti muthetse matope omwe akukakamizidwa pa tayala, omwe angapangitse kuti musowe pansi ndikugwa kumbali yanu.

TPI ndi chiyani?

 

Mtengo wa tpi wa tayala la njinga ndi kuchuluka kwa zingwe pa inchi iliyonse yamatayala, kapena kuchuluka kwa zapamadzi. Kutalika kwa mtengo wa TPI, kumachepetsanso kulemera kwa matayala, kumakulitsa kukhathamira ndi chitonthozo, ndikutsitsa kutsutsana. Matayala wamba a njinga amasiyana kuyambira 30tpi mpaka 120tpi, ndipo kusiyana kowonekera kwambiri pakati pawo ndi kulemera ndi makulidwe. Matayala a 30tpi ndi wandiweyani kwambiri, matayala a 60tpi ndiopepuka komanso opepuka kuposa matayala a 30tpi, ndipo matayala a 120tpi ndiopepuka komanso opepuka kuposa matayala a 30tpi. Wopyapyala ndi wopepuka nthawi yomweyo mtengo udzawonjezeka kwambiri. Nambala yayikulu ya TPI imatanthawuza kukana kutsika pang'ono. Matayala ambiri amakana chifukwa cha kusintha kwa mphira. Chifukwa jekete wapamwamba kwambiri amakhala ndi mphira wocheperako, amasintha mphamvu zambiri za wokwerayo kupita patsogolo.
