Ndingenza ntoni ukuba indawo engaphambili yebhayisekile yam endisandul’ ukuyithenga ikrwelwe?

Itsheyini ye-derailleur engaphambili yebhayisekile yentaba kufuneka ilungiswe. Amanyathelo athile ngala alandelayo:
1. Okokuqala lungisa indawo ye-H kunye ne-L. Okokuqala, lungisa ityathanga kwindawo engaphandle (ukuba yi-24 speed, yilungise ibe yi-3-8, i-27 speed ibe yi-3-9, njalo njalo). Lungisa isikrufu se-H se-derailleur engaphambili ngokuchasene newotshi, uyilungise kancinci nge-1/4 turn de le gear ilungiswe ngaphandle kokungqubana.
2. Emva koko beka itsheyini kwindawo engaphakathi (igiya eli-1-1). Ukuba itsheyini ikhuhlana kwipleyiti yesikhokelo yangaphakathi ngeli xesha, lungisa isikrufu se-L se-derailleur engaphambili ngendlela echasene newotshi. Kakade ke, ukuba ayikhuhli kodwa itsheyini ikude kakhulu kwipleyiti yesikhokelo yangaphakathi, , yilungise ngokwewotshi ibe kwindawo ekufutshane, ushiye umgama we-1-2mm.
3. Okokugqibela, beka ikhonkco elingaphambili kwipleyiti ephakathi uze ulungise u-2-1 kunye no-2-8/9. Ukuba i-2-9 ikhuhla kwipleyiti ekhokelayo yangaphandle, lungisa isikrufu esilungisa kakuhle se-derailleur yangaphambili ngendlela echasene newotshi (isikrufu esiphumayo); ukuba u-2-1 Ukuba ikhuhla kwipleyiti ekhokelayo engaphakathi, lungisa isikrufu esilungisa kakuhle se-derailleur engaphambili ngendlela yewotshi.
Qaphela: U-L ngumda ophantsi, u-H ngumda ophezulu, oko kukuthi, isikrufu sika-L silawula i-derailleur engaphambili ukuba ihambe ngasekhohlo nasekunene kwigiya yokuqala, kwaye isikrufu sika-H silawula intshukumo yasekhohlo nasekunene kwigiya yesithathu.
