Ma waho aʻe o ka nani, he mau hana ʻē aʻe kāna - e haʻi iā ʻoe i kahi "hui huila" maoli
ʻŌlelo pinepine mākou ʻaʻole ʻo ke apo hao poepoe (a i ʻole ke apo alumini) i hoʻouka ʻia me nā kaila he kikowaena maoli, ʻo kona inoa ʻepekema he "huila", no ka mea, ua hana ʻia ia me ke kila, no laila ua kapa pinepine ʻia ʻo "apo kila". No ka "kikowaena" maoli ʻo kona hoalauna, pili i ke kau ʻana o kahi kākoʻo ma ka axle (a i ʻole ke knuckle hoʻokele), ma ke ʻano maʻamau ma o nā bearings cone ʻelua i loko a me waho (hiki ke hoʻohana i kahi bearings pālua) i hoʻonohonoho ʻia ma ka axle, a hoʻopaʻa ʻia me kahi nati laka. Hoʻopili ʻia me ka huila ma o ka wili kaila, a me ka huila e hana i ka hui huila, i hoʻohana ʻia e kākoʻo i ke kaʻa a hoʻokele i ke kaʻa. ʻO nā huila a mākou e ʻike nei e wili wikiwiki ana, ʻo ia ke ʻano o ka wili ʻana o nā huila. Hiki ke ʻōlelo ʻia hoʻi ma nā ʻāpana ʻekolu o ka hub, rim a me ka kaila, he ʻāpana hana ka hub, ʻoiai ʻo ka rim a me ka kaila he mau ʻāpana passive. Pono e hoʻomaopopo ʻia ua hoʻokomo pū ʻia ka disc brake (a i ʻole ke kīʻaha brake) ma ka hub, a ʻo ka ikaika braking o ke kaʻa e halihali ʻia e ka hub.
