Modern bicycles differ significantly from those that were ten years ago and have already been practically rushed into the fly. The basic differences, with the exception of the appearance and manufacturing materials, is functionality. More precisely, the abundance of opportunities, in particular the possibility of switching gear. If the transmission is only one in old models, then there may be 5, 6, 7, 11 in the new ones, and even 27. To properly select and switch speeds, some rules should be known.
1
Under no circumstances should the transmissions shift when the bike is immobile. Such manipulations are guaranteed to break the device. Transfer switches exclusively while driving. It should be a good speed supply and the absence of a load on the chain.
2
The choice of optimal speed depends on a large number of factors: the state of the cyclist, roads, air temperature, pressure in wheels, slope of the route. But the most important of all to which the frequency of pedaling should be focused. Start better at low gear, gradually increasing it.
3
When hitting the mountain, when the maximum load, it is impossible to increase the transmission. On the contrary, it is necessary to choose the optimal one in advance and overcome the elevation. You can also switch speeds sharply. It is important to wait when the previous one completely got up and only then include the following.
4
The bicycle speed switching mechanism works as follows. The main direction of the front brake work is to throw the chain to the desired asterisks. When you need to change the speed, the special frame moves, occupying a position above a certain asterisk. With her jumps over the chain. The rear brake works in the same way, throwing the chain to the desired asterisk. Their difference is only that in the front brake is used to 3 stars, in the rear - to 9. In addition, due to the rear brake, the chain tension is ensured.
5
A bike in terms of switching speeds to a large extent resembles a car: for each locality there should be its optimal speed. This approach will provide a long life of the transmission of this unit.
Thus, compliance with all the above rules is a guarantee that consumables in their iron horse can be changed much less frequent if these simple rules will be ignored.
