TUTORIAL ADJUSTING THE FRONT DERAILLEUR

1) In order to adjust the front derailleur, install your bike on a workshop foot.

2) First, put the chain in the middle of the cassette, at the back of the bike.

3) To adjust the center chainring, check if the chain is rubbing against the derailleur. In our example, this is the case.

4) To adjust, completely loosen the adjustment screw at the derailleur lever.

5) Now the chain no longer rubs. You can then proceed to adjust the large plate.

6) In our example, the chain blocks. It is therefore necessary to make the adjustment using the set screw.

7) Tighten or unscrew the screw “H” until the chain no longer rubs. (Loosen the screw to shift the derailleur towards the right et tighten to shift it to left)

8) Test the adjustment to see if the stopper leaves the chain free.

9) Then adjust the stop of the small plate.

11) Test the gear shift.

11) You must now check the setting par relative to the position of the chain on the cassette. First, position the chain on the large chainring of the crankset and the smallest cog on the cassette.

11) If necessary, you can refine your adjustment by screwing or unscrewing the “H” screw. This setting allows the chain not to rub, regardless of the gear in gear.

11) Next, position the chain on the small chainring of the crankset and the largest cog on the cassette.

11) If necessary, you can screw or unscrew the “L” screw to refine your adjustment. In this example, the setting is good.

11) You now know how to adjust your front derailleur. Do not hesitate to consult our tutorials on bicycle transmissions in the event of a problem with your bike.
