How To Install A Rear Derailleur?
To install a rear derailleur, follow the manufacturer’s instructions.
In order to install a rear derailleur, you will need to first remove the old one. To do this, you will need to disconnect the chain from the derailleur. Next, use a derailleur hanger tool to remove the old derailleur. Once the old derailleur is removed, you can now install the new one. Start by attaching the new derailleur to the derailleur hanger. Next, connect the chain to the new derailleur. Finally, adjust the derailleur so that it is in the correct position.
What Size Rear Derailleur Do I Need?
The size of your rear derailleur is determined by the size of your cassette.
If you’re a mountain biker, the size of your rear derailleur is determined by the size of your cassette. For road bikes, it’s determined by the size of your chainrings. Most derailleurs will work with a range of cassette and chainring sizes, but it’s important to make sure that you have the right size for your bike.
Here’s a quick guide to help you choose the right size rear derailleur for your bike:
– If you have a cassette with 9 speed or less, you need a long cage derailleur.
– If you have a 10 speed cassette or higher, you need a medium cage derailleur.
– If you have a double chainring setup, you need a long cage derailleur.
– If you have a triple chainring setup, you need a medium cage derailleur.
Now that you know what size rear derailleur you need, let’s take a look at how to install it.
1. First, remove your old derailleur. If you’re not sure how to do this, consult your bike manual or take it to your local bike shop.
2. Next, attach your new derailleur to the frame. Most derailleurs have a hanger that attaches to a threaded hole in the frame.
3. Once the derailleur is attached, thread your chain through it. Make sure that the chain is running through the derailleur from the smallest cog to the largest cog.
4. Now, adjust the derailleur so that the chain is running smoothly through all the cogs. Consult your bike manual or take it to your local bike shop if you’re not sure how to do this.
That’s it! You’ve successfully installed a new rear derailleur on your bike.
How Do I Line Up The Rear Derailleur Hanger?
The derailleur hanger is the metal tab on the rear of the frame where the derailleur is mounted. It is important to align the hanger so that the derailleur is in line with the cogs on the rear wheel. This can be done by eye or with a derailleur alignment tool.
Here’s a step-by-step guide:
1. Find a straight edge that you can use to line up the hanger. This can be something like a wall or a door frame.
2. Place the bike so that the rear wheel is directly in front of the straight edge.
3. Look at the alignment of the hanger. It should be parallel to the straight edge.
4. If it’s not aligned properly, use an adjustable wrench to loosen the bolts that hold the hanger in place.
5. Adjust the hanger until it’s parallel to the straight edge, then retighten the bolts.
And that’s it! Just remember to check the alignment of the hanger periodically, as it can sometimes become misaligned over time.
A real-life example of this would be if you were to take your bike to a professional bike mechanic to have the rear derailleur hanger aligned.

How Do I Adjust Chain Tension With A Rear Derailleur?
To adjust the chain tension, you will need to turn the adjusting barrel on the derailleur. Turning it clockwise will tighten the chain, and turning it counterclockwise will loosen the chain. You will need to experiment to see how much tension is needed to keep the chain from falling off the cassette without rubbing.
There is no one-size-fits-all answer to this question, as the process for installing a rear derailleur will vary depending on the specific model and make of the derailleur. However, in general, the process for installing a rear derailleur will involve attaching the derailleur to the frame of the bicycle, and then connecting the derailleur to the shifter.
