If you are reading this then chances are you are wondering how to install a rear derailleur on a mountain bike. Hopefully this article on how to install a rear derailleur on a mountain bike has helped you. The most important factor when it comes to installing any new piece of equipment on your bike is making sure it works correctly. Making sure your new derailleurs are working correctly is crucial. Accidents do occur that may render your new derailleurs useless and in some cases the new derailleurs just break down from wear and tear.
To start this off I will talk about how the rear derailleurs work. When descending a hill or mountain trail your pedals push a shifter, which transfers power to a shifting cable via the front derailleurs pedal crank. The problem with some models of derailleur is that the shifting cable gets caught up in the crank arm, which makes it difficult to shift. If you have an older model then it’s recommended you replace the entire shift cable to prevent this problem.
Now that you know how the derailles work you need to know how to install a rear derailleur. The first thing you want to do is take off your back wheel. You should be able to pull the rear derailleurs mount off by hand, but in some cases you may need to use a screwdriver to remove them. Once you have removed them, it’s important you disconnect the mounting bolt. Once the bolt is disconnected you can slide the new rear derailleurs mount onto the rear of your existing frame.
Most manufactures provide charts that are helpful when learning how to install rear derailleurs. They are located inside your manual. In most cases the front derailleurs should face away from the rear derailleurs. If you have an older style drivetrain and your manufacturer does not make the front derailleurs with a face towards the rear, you may need to buy rear derailleurs that come with a face towards the rear. These were often made to allow manufacturers to continue to use the same drivetrain on their bikes even if other brands were available.
Once you have the new rear derailleurs mounted, you need to re-attach the shifter to its mount. If you removed the shift cable, you should skip this step and use a screwdriver to tighten the mounting bolt. If you were able to retain the shifters cable you should proceed to put it back on the bike.
Some of these older bikes will have bushings that are very easy to remove. If this is the case, there will be a series of nuts that are easily found. Usually, they are labeled like so-on-so-off. To install the new rear derailleurs you should remove the nuts and bolts from the previous set. There are usually new shifters already installed.
It is time to install the new rear derailleurs. Start by installing the cable guides under the bars and then install the cable itself under the seat. Once that is done, install the chain guides under the seat as well. Make sure you get it right the first time.
