Ko ngā take pea e kore ai e taea te whakahuri i te mekameka pahikara maunga, ā, ka mau:
1. Kāore i te tika te whakarite o te derailleur: I a koe e eke ana, ka mirimiri tonu te mekameka me te derailleur. I roto i te wā, ka wetekina, ka hē rānei te tūnga o te derailleur, ka mau ai te mekameka. E taunakihia ana kia haere koe ki te toa hoko waka ka tono ki te rangatira kia whakarite i te derailleur kia tika ai tōna tūranga, kia tika ai hoki te piri.
2. Kāore he hinu i roto i te mekameka: Ki te kore he hinu i roto i te mekameka, ka maroke wawe, ka pakaru, ā, ka piki ake te ātete ki te waku, ka piri te mekameka. E taunakihia ana kia tāpirihia he hinu whakahinuhinu e tika ana ki te mekameka i ia wā, i te nuinga o te wā kotahi i muri i ia ekenga.
3. Kua totoro te mekameka, kua tawhito rānei ngā taputapu: Ki te totoro te mekameka, ki te tino tawhito rānei ngā taputapu, ka raru pea te mekameka. He mea pai kia tirohia tonutia te tawhito o te mekameka me ngā taputapu, ā, me whakakapi tonu mēnā he raruraru.
4. Te whakatikatika hē o te derailleur: Ki te kore e tika te whakatikatika o te derailleur, ka kore pea e taurite te mekameka me ngā taputapu, ka piri te mekameka. He mea pai kia haere ki te toa hoko waka, ka tono ki te mekanika kia tirohia, kia whakatikatikaina hoki te tūnga me te piri o te tuku.
Mena kāore e taea e tētahi o ngā tikanga o runga ake nei te whakatau i te raruraru, he mea pai kia tukuna te motuka ki tētahi kaihokohoko hei tirotiro me te whakatika kia pai ai te whakamahinga o te motuka.
