Frequently Asked Questions
Which rear derailleur is the best?
There is no definitive answer to this question as it depends on a number of factors, including the type of bike you have, the type of riding you do and your personal preferences. However, we can narrow it down to a few contenders for the title of best rear derailleur.
For road bikes, the Shimano Ultegra R8000 Derailleur is a popular choice thanks to its smooth shifting performance and low weight.
If you’re looking for something similar but at a lower price point, the Shimano 105 R7000 Derailleur is also worth considering. For mountain bikes, the Shimano Deore XT RD-M8000 Rear Derailleur is a top pick for its durability and precision shifting, even under tough conditions.
Do some research and test out different models until you find the perfect match for your bike and riding style.
What is the best brand of a derailleur?
There is no definitive answer to this question as it depends on a number of factors, including the type of bike you have, the terrain you ride on and your personal preferences. However, some brands of derailleurs that are generally considered to be high quality and reliable include Shimano, SRAM and Campagnolo.
What is the difference between GS and SS rear derailleurs?
Rear derailleurs come in two different varieties: GS and SS. GS (long cage) derailleurs are meant for use with MTB cassettes that have a large range of gears (11-36t or 11-40t), while SS (short cage) derailleurs are designed for road cassettes with a smaller gear range (11-25t or 11-28t). The main difference between the two is cage length, which dictates how much chain the derailleur can take up.
A long-cage GS derailleur can take up more chain than a short-cage SS derailleur, making it better suited for use with mountain bikes that have a greater range of gears.
Can I put any rear derailleur on my bike?
It’s a common question, and one with a bit of a complicated answer. In short, you can put any rear derailleur on your bike, but it might not work as well as you hope. Different derailleurs are designed for different gear ratios, so putting the wrong one on your bike can cause some serious problems.
In order to figure out what derailleur you need, you first need to know what cassette is on your bike. The cassette is the cluster of gears that sits at the back of the bike (the rear cogset). Each cassette has a different range of gears, which is represented by the number of teeth on each cog.
For example, an 11-speed Shimano Ultegra cassette might have cogs with 11 teeth (the smallest), 12 teeth, 13 teeth, 14 teeth, 15 teeth, 17 teeth, 19 teeth and 21 teeth (the largest). The next thing you need to know is what chainrings are on your crankset. The crankset is the part of the bike where the pedals attach; it contains two or three chainrings (gears) up front.
Again, each chainring has a different number of teeth; for example, a 52/36 crankset has 52t and 36t chainrings. Most modern bikes will have either two or three chainrings; if yours has twochainrings , it’s probably something like a 50/34 or 52/36. If it has threechainrings , it might be something like a 42/32/24 or 44/32/22 .
Now that we know what kind of gearing our bike has , we can start to narrow down which derailleur we need .
If our bike has an 11-speed Shimano Ultegra cassette and a 52/36 crankset , we’ll need a long cage derailleur; this type of derailleur can accommodate cassettes with up to 32t difference between the smallest and largest cog. We would NOT want to use a short cage derailleur in this instance, because they’re only designed for cassettes with up to 28t difference between the smallest and largest cog.
Doing so would result in poor shifting performance, as well as increased wear and tear on both the drivetrain components and yourself! So there you have it: while you CAN put any rear derailleur on your bike, there’s definitely such thing as matching them correctly according to your gearing setup. Do yourself (and your wallet) a favor by doing some research ahead of time so that you don’t end up having to replace parts prematurely!
Conclusion
There you have it! The best rear derailleur for the folding bikes is the Shimano Sora RD-R3000! This product is durable, has a great reputation, and will give you the performance you need.
