Ke holomua mau nei ka ʻoihana kaʻa kaʻa i nā ʻenehana paikikala hou a me nā mea hou.
Eia nō naʻe, ʻoi aku ka maikaʻi o nā kaʻa kaʻa kaʻa, ʻoi aku paha ma mua o nā kaʻa kaʻa kaʻa kaʻa, ʻaʻole like ia me nā mea a mākou i holo ai he ʻumi makahiki i hala.
I ka moa-a-hua paha, ua lilo ka heihei kaʻa kaʻa keʻa i ka ʻenehana a me ka wikiwiki - e like me ka hoʻāʻo ʻana o Izu circuit ma ka 2020 Tokyo Olympics - a ua lilo nā kaʻa. ʻoi aku ka wikiwiki.
Ma kahi kokoke i kēlā me kēia hiʻohiʻona o ka MTB ma waho o ke alanui, ua hoʻololi ʻia i nā makahiki he ʻumi i hala aku nei, mai ka lōʻihi a me ka loose MTB geometry hiki ke ʻoki iā ia ma nā hiʻohiʻona ʻenehana a me nā ʻāpana pōhaku ʻoiai ʻo ia ka uila-wikiwiki piʻi piʻi) kekahi mau kaʻa. ʻO ka paikika mauna enduro maikaʻi loa.
ʻAʻole hiki iā mākou ke ʻōlelo ua hōʻeha mākou. ʻO kēia mau hoʻololi e hoʻolilo i ka holo kaʻa ma waho o ke alanui a me ka nānā ʻana i ʻoi aku ka leʻaleʻa a, i kahi pae, hoʻolalelale i ke ala no nā kaʻa kaʻa waho-alanui e hoʻohui i nā ʻāpana maikaʻi loa o XC a me nā kaʻa kaʻa waho-alanui.
No laila, me nā mea a pau i ka noʻonoʻo, eia nā ʻano ʻeono e loli ai nā kaʻa kaʻa ma waho, a no ke aha he mea maikaʻi ia no kēlā me kēia kaʻa kaʻa. nā paikikala maikaʻi loa ma waho o ke alanui.
'O ka nui o nā huila ka nui o nā ka'a ka'a XC, me nā ka'a mauna ma waho o ke alanui e ho'ohana ana i nā huila 29 iniha.
Ke nānā nei i nā makahiki he 10, ʻoiai e hoʻomaka ana ka poʻe holo lio e ʻike i nā pōmaikaʻi o 29 iniha, nui ka poʻe e hoʻopaʻa paʻa nei me ka liʻiliʻi, a hiki i kēlā manawa, ka nui maʻamau 26 iniha.
I kēia manawa, e hilinaʻi nō hoʻi ia i nā koi kākoʻo. Inā ʻaʻole hana kāu mea kākoʻo i kahi 29er, ʻaʻole hiki iā ʻoe ke holo inā makemake ʻoe.
A, he kumu maikaʻi ko lākou. Ua liʻiliʻi ka manawa o ka ʻoihana kaʻa kaʻa no ka loaʻa ʻana o ka geometry a me nā ʻāpana 29ers. Hiki ke palupalu nā huila, a hiki i ka lawe ʻana ke waiho liʻiliʻi i ka makemake, no laila ʻaʻole he mea kupanaha ke kānalua nei kekahi poʻe holo.
Eia nō naʻe, i ka makahiki 2011, ʻo ia ka mea holo mua i lanakila i ka Cross Country World Cup ma ke kaʻa kaʻa 29-inch. A laila lanakila ʻo ia i ka mekala gula cross-country ʻo 2012 London Olympics ma kahi 29er (Specialized S-Works Epic). Mai ia manawa, 29. -ʻO nā huila ʻīniha ua lilo i mea maʻamau i ka heihei XC.
ʻO ka wikiwiki i kēia manawa, a ʻo ka hapa nui o nā mea holo e ʻae i nā pono o nā huila 29-inihi no ka heihei XC. ʻOi aku ka wikiwiki o lākou, hāʻawi i ka traction a hoʻonui i ka hōʻoluʻolu.
ʻO kekahi hoʻololi nui ʻē aʻe no nā kaʻa kaʻa lepo (a me nā kaʻa kaʻa mauna ma ke ʻano nui) ʻo ia ka hiki ʻana mai o nā pahu kaʻa kaʻa mauna me ka hoʻopaʻa ʻana, kahi kaulahao ma mua a me kahi cassette ākea ma hope, ʻo ka maʻamau he 10 liʻiliʻi ma kekahi ʻaoʻao. 50-niho sprocket ma kekahi ʻaoʻao.
ʻAʻole pono ʻoe e hele i kahi mamao loa e ʻike i kahi kaʻa kaʻa me ka crankset triple i mua. Hoʻomanaʻo kekahi lālā o ka hui BikeRadar i kā lākou kaʻa kaʻa mua ma waho o ke alanui, e puka mai ana i ka makahiki 2012, me kahi crankset triple.
Hiki i nā kaulahao ʻekolu a ʻelua paha ke hāʻawi i ka mea hoʻokele me ka laulā maikaʻi o nā kaʻa a me ke kaawale kūpono no ka cadence kūpono, akā ʻoi aku ka paʻakikī o ka mālama ʻana a mālama i ka hana maikaʻi.
E like me nā mea hou, i ka wā i hoʻokuʻu ʻia ai kāna hoʻokele hoʻokahi i ka makahiki 2012, ʻaʻole maopopo ka nui o nā poʻe holo lio no ka mea, ʻo ka naʻauao maʻamau ʻaʻole e hana maoli nā pahu he 11 ma kahi ala ʻē aʻe.
Akā, ua hoʻomaka ka poʻe ʻoihana a me nā mea leʻaleʻa e ʻike i nā pono o ka mea hoʻokahi. ʻOi aku ka maʻalahi o nā Drivetrains e hoʻokomo, maʻalahi e mālama a hoʻemi i ke kaumaha ʻoiai e mālama ana i kāu kaʻa. ʻAʻole ia he derailleur mua e hoʻokaʻawale ai i ka haʻalulu hope.
ʻOi aku ka nui o ka lele ʻana ma waena o nā lākiō, akā ʻike ʻia ʻaʻohe mea e manaʻo a makemake maoli paha i ka spacing paʻa i hāʻawi ʻia e nā kaulahao pālua a ʻekolu paha.
Ke hele nei i kekahi heihei ma waho o ke alanui i kēia lā, manaʻo mākou he cog kēlā me kēia kaʻa, he mea maikaʻi ia i ko mākou manaʻo.
He laʻana maikaʻi loa ka Geometry no ka hiki ʻana i ka ʻenehana paikikala ke hoʻomau i nā koi o ke aʻo ʻana a hoʻomau i ka hoʻomaikaʻi ʻana. I ka lilo ʻana o ka heihei ma waho o ke alanui i ʻoi aku ka paʻakikī a ʻoi aku ka ʻenehana, ua ulu aʻe nā hōʻailona ma o ka hana ʻana i kā lākou mau kaʻa i kūpono no ka iho ʻana me ka mālama mau ʻana i ka hana piʻi. .
ʻO kahi hiʻohiʻona nui o ka geometry bike off-road hou ka Specialized Epic hou loa, e hōʻike ana i ka nui o nā mea hana ma waho o ke alanui.
He kūpono loa ka Epic no ka wikiwiki a me nā koi ʻenehana o ke alanui hou. ke hele wāwae a iho wikiwiki.
Hoʻohālikelike ʻia ka Epic o 2012 me ka mana hou. ʻO ka 70.5-degree head tube angle e ʻoi aku ka ʻoi o ke kaʻa, akā ʻo ia ka mea e hilinaʻi ʻole ai i lalo.
ʻOi aku ka pōkole o ka hiki ma 438mm, a ua lohi iki ke kihi o ka noho ma nā degere 74. Hiki i kahi kihi noho looser ke paʻakikī iā ʻoe ke kiʻi i kahi kūlana kūpono e pedal ma ka bracket lalo.
Pēlā nō, ʻo ka mea hou he kaʻa XC ʻē aʻe nona ka geometry i hoʻololi.
He mea pono ke hoʻomaopopo ʻia ke kahakiʻi nei mākou i nā laina mānoanoa ma ʻaneʻi. Ma waho aʻe o nā kiʻi geometry a mākou e ʻōlelo nei ma aneʻi, nui nā kiʻi a me nā mea e pili ana i ke ʻano o ka paʻa ʻana o ke kaʻa kaʻa ma waho o ke alanui, akā ʻaʻole e hōʻole ʻia ka loaʻa ʻana o ka geometry XC hou. Ua hoʻololi ʻia kēia mau kaʻa kaʻa i ka hilahila ke holo i lalo.
Manaʻo mākou inā ʻōlelo ʻoe i kekahi mea holo 'Olumepika 2021 he pono lākou e heihei ma luna o ka lāʻau kuʻi, e huhū loa lākou.
I loko o nā makahiki he ʻumi i hala iho nei, ua ʻoi aku ka nui o ke ʻano o nā huila ma ka ʻāina holo kaʻa, mai ka holo ʻana i ke alanui a hiki i XC, a ʻo nā huila kaʻa mauna maikaʻi loa i kēia lā he paʻa loa.
ʻO ka naʻauao maʻamau, ʻoi aku ka wikiwiki o ka holo ʻana o nā pana liʻiliʻi a mālama iā ʻoe i ke kaumaha.
ʻOi aku ka wikiwiki o lākou, hāʻawi i ka paʻa hou aku, hāʻawi i ka hōʻoluʻolu hou aʻe, a hiki ke hōʻemi i ka manawa o kahi puncture hiki ʻole.
Aia kekahi mau hoʻopaʻapaʻa e pili ana i ke kaʻa kaʻa ka wikiwiki loa, a ʻaʻole paha he pane maopopo i kēlā nīnau. Akā i kēia manawa, ʻike ʻia ka hapa nui o nā mea holo i ka 2.3-inihi a 2.4-inihi paha no ka heihei XC.
Ua holo mākou i kā mākou mau hoʻokolohua ponoʻī ma nā laula paʻa, e ʻimi ana i ka nui o nā huila wikiwiki loa no nā kaʻa kaʻa mauna a me nā puʻupuʻu paʻa wikiwiki loa no ke alanui.
E like me ka ʻōlelo ʻana a kekahi i loko o kahi kiʻiʻoniʻoni e pili ana i nā spiders, "me ka mana nui e hiki mai ana ke kuleana nui" a pēlā nō hoʻi i nā kaʻa kaʻa o waho o ke alanui.
ʻO kāu mau kaila i hoʻopaʻa ʻia, geometry a me ka nui huila e hāʻawi iā ʻoe i ka manawa e hele wikiwiki ai ma mua o ka manawa.
Eia hou, ʻaʻole pono ʻoe e hele i kahi mamao loa e ʻike i kahi kaʻa me kahi pahu lima ʻoi aku ka liʻiliʻi ma mua o 700mm. Ke nānā hou aku i hope, hoʻomaka lākou e luu ma lalo o 600mm.
I kēia au o nā kaola ākea, e noʻonoʻo paha ʻoe no ke aha e holo ai kekahi i kahi ākea haiki? ʻAe, ʻoi aku ka lohi o ka wikiwiki i kēlā manawa, a ʻoi aku ka ʻenehana o ka iho.
Laki no kākou a pau, i ka pi'i 'ana o ka wikiwiki, ke pi'i nei ka laula o ko mākou lima lima, a nui nā ka'a ka'a XC i ho'opa'a 'ia me nā pahu lima 740mm a i 'ole 760mm i hiki 'ole ke no'ono'o 'ia he 'umi makahiki aku nei.
ʻO ke ʻano like me nā kaila ākea, ua lilo nā lima lima ākea i mea maʻamau ma kēlā ʻaoʻao o ke kahua kaʻa kaʻa. .
Ua hiki mai ka hoʻomaha ʻana i nā makahiki he ʻumi i hala.
ʻO kēia mau hoʻomaikaʻi ʻana i ka ʻenehana hoʻokuʻu ʻia, me ka ʻoi aku o ka ʻenehana ma mua o ka wā, ʻo ia ka mea e ʻike ʻoe i kahi kaʻa kaʻa hoʻomaha piha ma mua o ka huelo paʻa i ka heihei XC kiʻekiʻe.
He kūpono nā Hardtails no nā papa a mākou i ʻike ai ma waho o ke alanui he ʻumi a ʻoi aku paha. Ua loli nā mea a pau. he paikikala hoʻomaha piha (Ua lanakila ʻo Victor i ka 2021 Men's Classic me ka hardtail, lanakila i ka heihei wahine hoʻomaha piha), ʻo ka hapa nui o nā mea holo i kēia manawa ke koho i nā hopena ʻelua i ka hapa nui o nā heihei.
Mai kuhi hewa iā mākou, aia nō nā huelo uila wikiwiki i ka XC—ʻo ka BMC i hoʻolauna ʻia i ka makahiki i hala he hōʻike ia o ka holomua ʻana o nā huelo paʻa ma waho o ke alanui-akā, ke aliʻi nei nā paʻa paʻa paʻa piha.
Ke holomua nei ka huakaʻi. E lawe i ka Scott Spark RC hou - ke kaʻa i koho ʻia no .He 120mm ka huakaʻi hele ma mua a ma hope, akā ua maʻa mākou i ka ʻike ʻana i ka 100mm.
He aha nā hanana ʻē aʻe a mākou i ʻike ai i ka ʻenehana hoʻokuʻu? E lawe i ka Brain Suspension i hoʻopaʻa ʻia e Specialized. Ma ke kumu, he manaʻo maikaʻi ia, akā ma ka hoʻomaʻamaʻa, ua hāʻawi ka lolo i nā mea hahai honua.
ʻO ka hoʻopiʻi nui loa, ʻo ia ka puʻupuʻu nui a i ʻole ka puʻupuʻu i manaʻo ʻia e ka mea holo i ka wā e wehe hou ai ka valve.
Eia naʻe, e like me nā mea a pau ma kēia papa inoa, ua hoʻomaikaʻi mālie ʻo Specialized i ka lolo i nā makahiki. Hiki ke hoʻoponopono ʻia i kēia manawa ma ka lele, a ʻoi aku ka palupalu o ke kani percussive ma mua o nā hanauna i hala.
ʻO ka mea hope loa, ʻo ka ulu ʻana o ka haʻalulu he kumu hoʻohālike nui o ka hoʻolālā ʻia ʻana o nā paikika XC o kēia lā i ʻoi aku ka mākaukau a me ka maʻalahi ma mua o ka wā ma mua.
ua hoʻokūkū ʻo ia i nā hanana like ʻole no nā makahiki he ʻumi, ʻo ia hoʻi ka ʻāina keʻa, ka marathon a me ka piʻi mauna, a i kēia manawa ke hauʻoli nei ʻo ia i kahi ola ʻoluʻolu, kū i nā hale ʻaina a inu pia ma hope o ke kaʻa kaʻa. ʻO ka manawa, hauʻoli nō ʻo ia i ka piʻi ʻana a me ka ʻeha ma nā kaʻa.
Ma ke komo ʻana i kāu kikoʻī, ʻae ʻoe i nā ʻŌlelo a me nā Kūlana a me nā Kulekele pilikino a BikeRadar. Hiki iā ʻoe ke wehe i ke kau inoa i kēlā me kēia manawa.
