Ndingenza ntoni ukuba i-derailleur yangaphambili yebhayisekile yam entsha endisanda kuyithenga ikrwelwe?

Itsheyini yebhayisekile yentaba yangaphambili ifuna ukulungiswa.Amanyathelo athile ngala alandelayo:
1. Qala ulungise indawo ye-H kunye ne-L.Okokuqala, lungisa ikhonkco kwindawo engaphandle (ukuba isantya se-24, yilungise kwi-3-8, i-27 isantya ukuya kwi-3-9, njalo njalo).Lungisa i-screw ye-H ye-front derailleur counterclockwise, uyilungelelanisa ngokucothayo nge-1/4 ukujika de le giya ihlengahlengiswe ngaphandle kokukhuhlana.
2. Emva koko ubeke ikhonkco kwindawo engaphakathi (i-1-1 gear).Ukuba ikhonkco likhuhla kwipleyiti yesikhokhelo yangaphakathi ngeli xesha, hlengahlengisa isikrufu se-L se-derailleur yangaphambili ngokuphikisana newotshi.Ngokuqinisekileyo, ukuba ayihliki kodwa ikhonkco ikude kakhulu kwi-plate yesikhokelo sangaphakathi, , yilungise i-clockwise ukuya kwindawo esondeleyo, ushiye umgama we-1-2mm.
3. Ekugqibeleni, faka ikhonkco langaphambili kwi-plate ephakathi kwaye ulungise i-2-1 kunye ne-2-8 / 9.Ukuba i-2-9 ikhuhla ngokuchasene nepleyiti yesikhokhelo yangaphandle, lungisa isikrufu esingaphambili se-derailleur's fine-tuning screw ngasekunene (isikrufu esiphumayo);ukuba 2-1 Ukuba ikhuhla ngokuchasene nepleyiti yesikhokhelo sangaphakathi, hlengahlengisa isikrufu esingaphambili se-derailleur's fine-tuning screw.
Qaphela: L ngumda ophantsi, H ngumda ophezulu, oko kukuthi, i-screw ye-L ilawula i-derailleur yangaphambili ukuba ihambe ngasekhohlo nasekunene kwi-1 yegiya, kwaye isikrufu se-H silawula intshukumo yasekhohlo nasekunene kwigiya yesi-3. .
