The technology of mountain bike today becomes more complicated and complex, but as bike owner we have to learn about simple and basic things on having mountain bike; the derailleur. Derailleur system is one of the old technology, and have improved for certain scene of biking. Basically the derailleur on cross country bike is same as the derailleur on all mountain bike, so the knowledge about this part is very important.
On this first session of "Bike Guide", we will learn more about "how to install the rear derailleur." But some tools will be needed to install the rear derailleur, and we can assume that we all have basic tools for mountain bike.
The installation is simple but the complex thing is how to set up so the shifting and rear derailleur have good acceleration. This is important, because when the shifting system is not good, this will be problem if we want to climb but the rear derailleur have not in good response. Then, how to make it have good response? The step is we can preset the high limit (H) and then drift the shift wire back to the derailleur. Then find a bare stretch of cable and give it a good pull to make sure the cable is seated and has no slack. Then loosen the wire, pull it tight again and re-tighten it.
