Momwe mungasankhire njira yanu kutengera mtundu wanu komanso momwe mukufuna kukwaniritsira.

Pakadali pano njinga zamapiri zikuluzikulu zimabwera m'mitundu itatu: mainchesi 26, mainchesi 27.5 (omwe amadziwikanso ndi 650b) ndi mainchesi 29 (omwe amadziwikanso kuti 29er). Tiyenera kudziwa kuti izi zimatanthauzira mulifupi wa tayala lakunja, osati mulifupi mwake. Mwachitsanzo, mawilo 26 inchi ali ndi mulifupi wozungulira mamilimita 559, kapena mainchesi 22.

 

Mainchesi 26 ndi njira yachikhalidwe kwambiri ya mawilo. Ma bikini apakati mpaka kumapeto anali mainchesi 26 mulifupi, ndipo opanga ambiri akupanga njinga zamapiri 26-inch lero.

M'zaka zaposachedwa, njinga zamapiri zokhala ndi misewu yayikulu zakhala zotchuka ndipo zatchuka pamipikisano ya akatswiri komanso oyendetsa njinga zamasewera. Mwachitsanzo, njinga yamapiri ya 29er ili ndi mphika wa 622mm, wofanana ndi njinga yamsewu. Misewu yayikulu kwambiri imalola kuti anthu azitha kuyenda bwino mukamayenda pamtunda komanso pamipata. M'chigawo cholimba mungagwiritse ntchito "bigfoot" ngati pamalo athyathyathya kuti aphwanye miyala yaying'ono, misewu ndi zotsika. Mu njinga yamoto ya XC (yopanda malire), mutha kupeza mwayi waukulu

 

Kuthamanga: chiwonetsero cha 27.5-inchi chimayamba mwachangu, pomwe mtundu wa-inchi 29 ndiwofunikira bwino kuti kuthamanga kuthamanga.

 

Ma diamita ang'onoang'ono amayendetsa mwachangu kuposa diameter zazikulu chifukwa chakulemera kwa magudumu. Ma wheel of the main wheel wheel, mkombero, ndi matayala amkati ndi akunja amalemera kwambiri kuchokera pakati pa gudumu, zomwe zimapangitsa kuthamanga kwambiri komanso kuthamanga kwam'munsi, zomwe zimapangitsa kuyenda kosavuta. Kupanda kutero, kuthamanga kumachulukitsa, kuchuluka kwa kuzungulira kumachepa, ndipoulendo wapamtunda umakhala wovuta.

 

27.5 mainchesi: Poyerekeza ndi mainchesi 29, kuthamangitsa mwachangu nthawi zambiri kumawonedwa ngati imodzi mwamaubwino kwambiri panjira ya 27.5, ndikupangitsa kuti ikhale yoyenera kwambiri kwa okwera okalamba, okalamba.

Mainchesi 29: kuyamba pang'onopang'ono, nthawi yayitali yothamangitsanso yofunikira kuti ifike kuthamanga kwambiri, komwe kumatha kubwereranso momwe woyendetsa amayendetsera ndikukoka komanso kulephera kuthamangitsa. Komabe, liwiro loyenda likangofika, limathamanga kwambiri komanso kuyenda bwino kwa nthawi yayitali kuposa yamagalimoto ang'onoang'ono, omwe amafunikira mphamvu zochepa kuti akhalebe othamanga.

 

Gwirani: matayala akunja 29 "okhala ndi matayala akunja amakhala ndi malo okulirapo komanso olimba kwambiri (poyerekeza ndi kapangidwe komweko).

 

27.5 ": mkombero wa gudumuwu umagwira bwino pamisewu yambiri. Ngati kuwunikiridwa kwathunthu kwa zinthu monga kuthamanga ndi kulemera kwawonjezeredwa, mtundu wama wheel wheel ungasankhidwe pomaliza.

Mainchesi 29: ngati mukukwera xc yolemetsa kwambiri yokhala ndi miyala yambiri komanso zotumphukira zomwe zimafunikira kuti musayende bwino, galimoto yolumikizana kwambiri ndikubetcha kwanu kopambana.

Angle ya kuukira: mainchesi 29 ndiosavuta kumveka.

Angle ya kuukira amatanthauza Angle yomwe imapangidwa pakati pa malo olumikizirana ndi malo olumikizirana pomwe gudumu likuyanjana ndi chopinga cha mraba. Zocheperako zomwe zimapangitsa kuti ziwonongeke, ndizosavuta kudutsa.

Mainchesi 27.5: zosavuta kupitilira ngati 29, komabe njirayo yabwino. Kuphatikizidwa ndi kalembedwe kanu, ngati mumathera nthawi yanu yambiri pa kavalo wam'mapiri kapena m'misewu yotsika, mawonekedwe a 27.5 ndi abwino kwa inu.

Mainchesi 29: mawilo amakhala ndi Angle yotsika pang'ono kuposa 27.5, yolola kukwera bwino matanda, miyala, ndi madontho, pomwe matayala akulu amapatsa okwera chidaliro chambiri pamavuto amisewu.

Kunenepa: Mtundu wa mainchesi 27.5 ndi wopepuka.

Palibe kukayikira pa izi. Mitundu yayikulu ikuluikulu imagwiritsa ntchito zinthu zambiri, motero iyenera kukhala yolemera. Mu kalasi yomweyo, mitundu 29 imalemera pafupifupi 1kg kuposa mitundu 27.5.

 

Kutengera mtundu wamakwera anu, kulemera kwa njinga yanu mwina kungakhale kosafunikira kwenikweni. Mukangokwera modzidzimutsa, mwina simungakhale ndi chidwi ndi kulemera kwa njinga yanu. Ngati mukupikisana nawo pamsewu, kapena ngati mukufuna kuthamanga mtunda wautali, ndiye kuti muyenera kuchepetsa kulemera kwa galimotoyo. Kugwiritsa ntchito BMD ndi njira imodzi yochepetsera kulemera, koma si njira yokhayo.

Kukweza gudumu lomwe limakhomera matayala osavomerezeka ndi njira ina yabwino yochepetsera kunenepa. Matayala othamanga samangochepetsa kulemera kwa galimotoyo, komanso imathandizira mwachangu chifukwa chakuchepetsa mphamvu yozungulira, komanso kuphatikiza kwakukulu kwa kugwirira bwino pakuchepa kwa tayala.

Kugwira: Mitundu 27.5 ndiyosavuta kuyigwira.

Pamodzi ndi mawilo owonjezereka, chimangacho chimakhala ndi wheelchair, chomwe chimatha kupangitsa kuti mokhotakhota muvute.

Ngati mumakonda kukwera misewu yopapatiza yokhala ndi ma curve angapo, mutha kusankha mawonekedwe a 27.5-inchi, omwe amakhala ndi mwayi wama 26 mainchesi osinthasintha mukadali ndi maubwino ena pakungodutsa. Ndikosavuta kuthana ndi zopinga mumayendedwe a mainchesi 29, chifukwa chake mwina simungamve kuyendetsa kanjira kakang'ono ka magudumu, kuti muthe kudutsa pamiyala ndi mizu yamitengo m'malo moyenda mozungulira iwo.

Sankhani mtundu wamanjinga: wankhanza, wamba, waluso kapena zina; Fotokozani cholinga chanu chokwera, monga ulendo wokwera, mtunda wautali, maphunziro, mpikisano, ndi zina zambiri. Ngati simukudziwa mtundu wamtundu wanji womwe mukufuna, njira yabwino kuti mumve nawo ndikupita kumalo ogulitsira njinga kapena kukwera ndi bwenzi.
