Bicycles are equipped with gear selection mechanisms. With their help, you can change the frequency of pedaling, and the effort on them begins to effectively distribute energy. So that you can change gears on the go, the bike has various types of switches. In this article, we'll talk about setting up one of them.

In order to set up the front derailleur of a bicycle correctly, you need to have a good eye and patience. The moment force is applied to the pedal, it will be transmitted from the top of the chain to the rear sprockets. It is not always possible to count on the derailleur to operate smoothly when the pedal is being actively moved, even when the rear shifting works flawlessly.

Setting the front derailleur is the hardest part. It will depend on the fastening to the frame itself. This must be done correctly and only then begin to adjust the limiters. When doing this, consider the height and angle.

When adjusting the front derailleur, you need toaccurately determine the angle. This must be done looking at the frame from top to bottom. Unfortunately, with modern switching mechanisms it is not always easy to correctly determine which position is correct. At the moment of rotation of the back of the frame, it must definitely move away from the frame.

Setting the front derailleur should be on the small sprocket of the system. This will prevent the chain from kicking off the big sprocket if it is adjusted so that the crank does not touch the frame. The result is a good front derailleur setup.

For the quality of the shift, the height of the front derailleur is very important. It must be remembered that manufacturers recommend making the distance between the large star and the outer part of the frame 2 mm. The lower this mechanism is lowered, the better the shifting will become, which does not require additional adjustment.

Tuning the front derailleur will correct any mismatches. Therefore, it is necessary to ensure that the curvature of the frame coincides with the curvature of the large star, and if it is less than the calculated switch, this gives a normal switch. Therefore, we can assume that the setting of the front derailleur is correct. However, an adjustment may be required in cases where the back of the frame is higher.

To do this, it is necessary to achieve an exact match between the curvature of the frame and the sprocket, to which the switch must be placed very close, ensuring reliable chain control. Thus, the limiter will not give him low gears and will eliminate the chain reset from the small sprocket of the system.

Adjusting the front derailleur allows the high limiter to be adjusted in such a way as to achieve such a position in which the chain in the highest gear will rub against the frame from the outside of it. In this way, it will not be necessary to frequently adjust at the time of the reverse gear change.
