Setting the front bicycle switch

Bicycles are equipped with gear selection mechanisms. With their help, you can change the speed of the pedals, and the effort on them begins to effectively distribute the energy. In order to change gears on the move, various kinds of switches are provided in the bicycle. In this article, let's talk about configuring one of them.

To adjust the front bicycle switch correctly, you need to have a good eye and patience. At the moment when an effort 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 expect the switch to function smoothly when the pedal is active, even if the rear switching works flawlessly.

Setting the front speed selector is the most difficult task. It will depend on the fastening to the frame itself. This must be done correctly and only then start to adjust the limiters. It should take into account the height and angle.

When setting the front switch, it is necessary to accurately determine the angle. This should be done looking at the frame from top to bottom. Unfortunately, modern switching mechanisms do not always easily determine correctly which position is correct. At the moment of rotation of the rear part of the frame, it must necessarily move away from the frame.

Adjustment of the front speed selector should occur on a small system sprocket. This will prevent the circuit from being dropped from the big star if you fit it on the rod so that the connecting rod does not touch the frame. The result is a good adjustment of the front switch.

For the switching quality, the height of the front switch is very important. It should be remembered that manufacturers recommend making the distance between the big star and the outer part of the frame at 2 mm. The lower this mechanism is lowered, the better will be the switching, which does not require an additional fit.

Setting the front switch allows you to correct any mismatch. Therefore, it is necessary to achieve that the curvature of the frame coincides with the curvature of a large star, and if it is less than the calculated switch, this gives a normal switch. Therefore, you can assume that the front switch setting is correct. However, it may be necessary to fit in cases where the rear of the frame is higher. To do this, it is necessary to achieve an exact coincidence of the curvature of the frame and the asterisk, to which it is necessary to put the switch very closely, ensuring reliable control of the circuit. Thus, the limiter will not give him low transmissions and eliminate the dumping of the circuit from the small system sprocket.

The setting of the front derailleur allows the high speed limiter to be adjusted to achieve a position in which the chain in the higher gear will rub against the outside of the frame. Thus, at the time of switching the rear gear, it will not be necessary to frequently perform a fit.
