Adjusting the speed of the bicycle: the features of the process

The mechanism of switching of speeds is veryan important element of modern sports and mountain bikes. There are many different systems, but the principle of their adjustment is almost the same. First of all, clean the mechanism of debris, dust and dirt. Now look at the switch. It has the restriction of extreme positions, which are indicated by the letters "H" and "L". Often the problem is to pull the cable, which you just need to pull up.

Before adjusting the speed switchingon the mechanic, you need to combine a small star with rollers. The bicycle chain should also be set correctly. On the front mechanism, it must hang on the biggest star, and on the back - on the smallest. In this case, you need to monitor the stretch of the cable. Now you can test the regulator. To do this, switch the speed lever one division down, after which the chain should be on the next star. If this does not happen, you need to debug the cable tension.

If you observe a heartbeat, then the adjustmentThe switching of speeds on a bicycle begins with checking the parallelism of the stars and the switch frame. Also pay attention to the height of its installation. At the same time, remember that you do not need to use the last two transmissions. This is a general concept of debugging a regulator.

Since in the process of increasing or decreasingSeveral mechanisms take part in the speed, then each of them must be considered separately. Adjust the switching from the rear of the system. First of all, make sure that the lever with the rollers, which facilitates the transfer of the chain from one star to another, is not bent. If this is the case, then the fastening should be leveled.

Adjustment of gear changes on the bicycle,front switch, is very simple. The main requirement is its correct installation. Take care that the frame was installed parallel to the stars, and the distance between them was 1-3 mm.

To begin with, put the smallestspeed. Now you need to slightly loosen the cable and twist the screw with the inscription "L". In this way, you adjust the required distance between the star and the frame. After that, the cable can be fixed back. Now you can set the maximum speed with a screw labeled "H".

After all the settings, check the bike formovement. If the chain does not jump well enough from one star to another, adjust the cable. Adjustment of the speed change on the bicycle should be made at the first detection of problems. For example, if the chain skips during the scrolling of the pedals, then in this case it is necessary to completely change it, since it is stretched. In doing so, it must not be tilted during the gearshift.

Also check the cable fordamage and fracture. In severe cases, it requires a complete replacement. It also happens that you have to install a completely new mechanism. So, adjusting the speed of the bicycle is a fairly simple procedure that you can do yourself.
