Yini okufanele ngiyenze uma i-derailleur yangaphambili yebhayisikili lami lasezintabeni esanda kulithenga liklwejwa?

Iketango le-derailleur yebhayisikili lasezintabeni langaphambili lidinga ukulungiswa.Izinyathelo eziqondile zimi kanje:
1. Okokuqala lungisa ukuma kuka-H no-L.Okokuqala, lungisa iketango endaweni engaphandle (uma ijubane elingu-24, lilungise libe ngu-3-8, isivinini esingu-27 kuya ku-3-9, njalonjalo).Lungisa isikulufu esingu-H se-derailleur yangaphambili ngokuphambene newashi, usilungise kancane ngokujika okungu-1/4 kuze kube yilapho leli giya lilungiswa ngaphandle kokungqubuzana.
2. Bese ubeka iketango endaweni engaphakathi kakhulu (igiya le-1-1).Uma iketango ligudla ipuleti likamhlahlandlela wangaphakathi ngalesi sikhathi, lungisa isikulufu esingu-L se-derailleur yangaphambili ngokuphikisana newashi.Yiqiniso, uma ingahlikihli kodwa iketanga likude kakhulu nepuleti yomhlahlandlela wangaphakathi, , ilungise ngokwewashi endaweni eseduze, ishiye ibanga lika-1-2mm.
3. Ekugcineni, beka iketango langaphambili epuletini eliphakathi futhi ulungise u-2-1 no-2-8/9.Uma 2-9 ehlikihla kupuleti lomhlahlandlela wangaphandle, lungisa isikulufu sokulungisa kahle se-derailleur ngokuphikisana newashi (isikulufu esiphumayo);uma 2-1 Uma ihlikihla kupuleti lomhlahlandlela wangaphakathi, lungisa isikulufu sokushuna kahle se-derailleur ngokwewashi.
Qaphela: L umkhawulo ophansi, H umkhawulo ophezulu, okusho ukuthi, isikulufu se-L silawula i-derailleur yangaphambili ukuze ihambe kwesokunxele nakwesokudla ngegiya lokuqala, futhi isikulufu sika-H silawula ukunyakaza kwesokunxele nesokudla egiyeni lesi-3. .
