3. INKESKY Shimano Rear Derailleur RD-TZ31-A 6/7 Speed Hub Bolt Mount – Best Budget Pick
The INKESKY Shimano rear derailleur is designed for bikes that are regularly used. Even if you’re using a bike that you bought from Walmart, you’ll be able to fit it in that.
This bike is among the least expensive derailleurs from Shimano. What got it to third place in our list is the value it provides in contrast to its price. You’ll get a lot of features that mid-tier derailleurs provide, and the quality is decent too.
It comes with plastic housing on both the top and the bottom of the pivot, and this makes the derailleur seem a bit flimsy. Despite the outlook and the first impression that you might have on it, you’ll soon find out that it’s very durable and capable of handling years of abuse.
One thing most people complain about this derailleur is the installation procedure. This is tougher to install than most other derailleurs. The hanger mount doesn’t get much tight, so you might require extra hands.

It’s also very universal when it comes to different bike types. You’ll be able to fit this on mountain bikes, fat bikes, and even road bikes, and you’ll get a great performance out of every one of them.

If you’re using an older version of this series, then you’ll experience a great change over the previous product, and we highly recommend changing.
The installation process of this derailleur is a bit different from the previous versions. Although the alignment will be a bit tough to adjust initially, you’ll be able to get it in a perfect position by investing some time.

First of all, it’s extremely easy to install. The manual doesn’t tell you much about the installation procedure, and it also requests you to let a professional take care of the installation process. Still, it’s easy to install, and you’ll be able to do so with the help of the internet.
If you’ve got a mountain bike with a 2*8 configuration, then this derailleur will serve you best. The cage of this is very precise, and there will be minimal to no chain rub even when you’re cross chaining. When you’re going uphill, you’ll be able to shift to a smaller chainring even under the load.
Adjusting and tuning this derailleur is straightforward. You’ll be able to set the high and low limits easily, and getting a separate barrel will help you fine-tune it even more.

For starters, the cable pull of this derailleur will remain very straight. You won’t even require a barrel adjuster, which will definitely save your money.
The installation process is quite easy as well. Unlike some other derailleurs, this one doesn’t require you to remove the cable for installing the derailleur, which is great. The trim function works perfectly too.
One drawback of this derailleur is that it doesn’t come with any instructions. The instruction manual provided doesn’t offer much in terms of value. However, it’s not actually a drawback as there are tons of YouTube videos that’ll help you with the process. Even if you’re new to this, you’ll be able to set it up perfectly.
- Top-quality front derailleur

8. SHIMANO RD 5701 105 30T Max Rear Derailleur – Best For Crisp and Preserving Shifting Experience
Next up, we have the Shimano RD 5701 derailleur at the eight places on our list. This isn’t among the best derailleurs offered by Shimano, but it’s still capable of getting the job done for entry-level bikers.
This derailleur comes with an extra stiff gear shifting that will give you an accurate and crisp experience.
It also comes with the wide link design that Shimano has been integrating into their latest models. This extra feature will not only provide you quick and crisp shifts but also help you keep the pivots for a longer time period.
With the help of this feature, you’ll get a derailleur that’s long-lasting and can provide a crisp experience in the long term. It’s also capable of accepting 30t cassettes of a wide range.

9. SHIMANO Tiagra 10-Speed Rear Road Bicycle Derailleur – RD-4700 – Best For Budget Shimano Combination
The Shimano Tiagra rear derailleurs are good budget picks, and these are considered entry-level derailleurs. If you’re looking forward to installing an entire Shimano component group in your bike at a reasonable price, then this is a component that you must consider buying.
Despite being an entry-level derailleur, these will provide a great performance to you. They offer some good features that are found only in the mid-tier derailleurs, and getting these features from such a budget pick is quite surprising.
These work great if you equip other Tiagra components in your bike. It’s not among the lightest derailleurs out there, but it gets the job done, which makes it worthy of your money. It looks sleek, and it’s very responsive when it comes to gear shifts.
You won’t need to adjust these too much for getting the maximum performance out of them. In fact, you’ll be able to use these properly, even without tuning. However, we recommend some tuning for getting the max potential out of them.

10. SHIMANO RD-M2000 Rear DERAILLEUR – Best for Rough Trails
Last but not least, we have the Shimano RD-M2000 rear derailleurs. These derailleurs offer a low-profile and sleek outlook, and they also offer a single chain construction.
The spring construction of these derailleurs is far stiffer than the rest. This will provide you a snappy and crisp shifting experience. Then again, the stiff design also reduces the chain slap to a great degree. If you buy an aftermarket chain guide tensioner, then you’ll be able to eliminate any chain slap.
If you don’t have any prior experience of reducing the chain slap, then it’ll be tough for you to adjust it. In such a case, we highly recommend that you go to someone who knows how to do this. The instruction manual doesn’t address this issue at all.
This unit is made for supporting 8 speed and 9-speed shifters. The shifting experience is smooth and crisp. If you’re a person who treads on rough trails, then this is the best budget pick for your bike.
Despite offering these amazing features, this derailleur comes at a very reasonable price. This is why we highly recommend it.
- Offers a smooth and responsive shifting experience
- Capable of eliminating chain slap
- Performs amazing on rough and rocky trails
- Comes at an affordable price
- Can’t be tuned properly by inexperienced users
- Manual doesn’t provide much information on adjusting chain slap
Features to Look for Before Buying
In this section, we’ll discuss the factors that will help you choose the right derailleurs for your bike. So, let’s get started.
Most of the expensive derailleurs weigh much less than the cheaper ones. Lighter derailleurs are definitely better as they won’t weigh you down, reducing the force you need to exert for riding.
However, this doesn’t necessarily mean that the lightest derailleur will serve you the best. While weight is definitely a factor to consider, you also need to consider the features that you’re getting out of the product. If a heavier derailleur is capable of meeting your requirements, then there’s no need to avoid that.
The finish is very subjective, as bikers are equally divided into two groups, one of which favors jazzy and glittering derailleurs, the others don’t care.
There are expensive derailleurs that will offer you a beautiful and polished outlook. These will definitely make your bike stand out from the rest, and the outlook itself will express the premium value of the product.
However, if you’re okay with derailleurs that don’t look all premium, that’s okay, and it’s completely your choice.
Choosing the right cage length for your derailleurs is extremely important. The length of the derailleur will determine whether it’s a fit for your bike or not.
If the cassette installed on your bike is of a wide range like 10-42t or more, then you’ll need a long cage derailleur. Then again, if the difference between the chainring sizes is great, a long cage derailleur will serve you best.
Then again, if the cassette size is regular and the drivetrain is either 1x or 2x, then a medium cage derailleur will be the better choice for you.
Finally, if you’re running a road bike with a regular cassette, then we highly recommend getting a short cage derailleur.
Number of Gears
Determining the number of gears on your bike is important as it’ll determine whether the derailleur will suit your bike or not.
If you already have a derailleur on your bike, then we recommend counting the number of cogs on the existing derailleur’s cassette. Get a derailleur that matches the same number.
On the other hand, if you didn’t have a derailleur before, we recommend the number of steps on the shifters. Add 1 to the number you’ve found, and this is the number of gears that you’ll need from your derailleur.
Frequently Asked Questions
Clutch derailleurs come with a bit different mechanism than regular derailleurs. Whereas the regular derailleurs rely on the main pivot for providing the tension, the clutch derailleurs provide an extra clutch that can increase this tension and hold it properly.
Due to the clutch derailleurs, the bike can shift between different gears quietly and more reliably. This is why the clutch derailleurs were used in the mountain bikes previously.
The highest number of slack chains that the rear derailleur cage can handle is known as the drivetrain capability. The higher the potential slack of the derailleur, the bigger cage you’ll need.
You can calculate the drivetrain capacity of your bike by adding the difference between tooth numbers on the largest and smallest sprockets on the cassettes and the difference between the tooth numbers on the smallest and largest chainring.
The rear and front derailleurs are different, and they also serve a completely different purpose. Now the chain becomes tense when you pedal your bike. In this state, the function of the rear derailleur is to keep the chain in a suitable position.
On the other hand, the front derailleur is supposed to move the upper part of the chain. Together, the front and the rear derailleur can keep your bike moving in the roughest trails.
For indexing your bike’s gears, you need to follow these steps:
1. Adjust the limit screw
2. Turn the barrel adjusted clockwise for tightening it
3. Tune the cable tension
4. Shift the cable to the largest sprocket
5. Adjust the B-tension screw
Sadly, no. Even if you get Shimano components all across the bike, you might face some problems. For example, if you’re going for the Shimano Tiagra derailleur, then you’ll need Tiagra components all across the board. Otherwise, it won’t be compatible.
Yes, it’s possible to force a derailleur to suit with any components- almost. However, you won’t be able to do it if you don’t have vast experience working with derailleurs.
Yes, there are slight differences between 10 and 11 speeds. However, you won’t need to replace the crankset, as swapping out the chainrings will help you adjust them.
If you’re willing to upgrade the derailleurs of your bike, then this is the right time to do so. You’ll find the Shimano Derailleurs best to worst ranked in the list above, and you’ll be able to find the most suitable one for yourself following the buying guide.
We strongly suggest you pick from this list as these are the best products that you’ll find on the market.
