Top & Best Bicycle turnstile: How to choose the best part in 2021?
How good it would be if all the streets were straight, smooth and smooth. As they are unfortunately not, you need strength, endurance and also gears on your bike. You then need a bicycle ratchet,
The turnstiles do the “dirty work” on the bikes, so that your pedaling is clean and lighter in any situation. In the Guide we set up below, we will show you all about this important piece, and help you choose the best and most suitable for your skinny girl.
First, the most important
- The bicycle turnstile is the part responsible for the gear ratio system.
- The ratchet is necessarily positioned on the rear wheel. The front wheel part is the crown.
- The basic variety of the bicycle turnstile is between the so-called free wheel turnstile and the cassette turnstile.

From the simplest bike to the model with the most varied gears, the bicycle turnstile is there to relieve and adapt your pedaling to the most diverse situations, whether uphill, downhill, tracks or roads.
In this Shopping Guide, we will talk about these situations and everything else that surrounds this very important gear. With the information we share below, you will have no trouble finding the turnstile for your bike
What is a bicycle turnstile?
The ratchet is a piece necessarily located on the rear wheel of a bicycle. It is a small gear, which by mechanical force, that is, its pedaling, gives strength to a larger gear, the crown, which makes the bicycle move.
Its basic design is like a stack of serrated discs, which decrease in circumference from the first – which is threaded clockwise in the rear wheel hub – to the last disc, which is connected to the frame.
The chains of the ratchets, also called pinions or teeth, are fitted with the bicycle chains, responsible for transferring the energy from the rear wheel to the front and vice versa.
The ratchet is by far the most pressed part during a ride. This makes the fitting on the wheel tighter and tighter, requiring periodic removal and maintenance so that it does not become too tight, which damages the ratchet itself and the parts around it, or even gets stuck on the wheel.
What is a bicycle ratchet for?
In addition to the basic movement of the bicycle, the ratchet is the responsible part in making the entire gear ratio work. The gears are a mechanical advent of the bicycle that enhance or relieve the cyclist’s pedaling, in order to adapt the necessary force for some track.
In other words, they make it possible, for example, when going uphill, to pedal lighter than on a single speed bike . Gravity is the same and effort is still required to climb, but in a much more comfortable pedaling.
Each knurled disk of this big stack that is the bicycle ratchet corresponds to one speed, and each speed corresponds to one, two or three gears, depending on the number of teeth in the crown, the gear similar to the ratchet on the front wheel.
When changing a gear, you make the chain, the one that connects the ratchet to the crown, “jump” from one serrated disk to the other, and drive a smaller disk, and therefore a higher speed, or a larger disk, and a lower speed .
Is it worth using a freewheel ratchet?
Some say that all turnstiles have free wheels. The question is where it is positioned.
Anyway, when talking about freewheeling ratchet, the referred model is the most basic ratchet, the traditional ratchet. It is threaded on the bicycle hub, and is responsible for turning the gear ratio system.
Also called a free wheel is the mechanism that turns with the transfer of energy from the pedals. It is responsible for making the wheel move.
Currently, the biggest advantage of this type of ratchet is its price, much lower in comparison to other varieties.
Even so, it has a better performance in urban use, which even though it is daily for many people, requires much less of the bicycle, and therefore less maintenance of the ratchet, which is usually the inconvenient part.
Another drawback is that the freewheel ratchet is not recommended for use at more than seven speeds. There is also the question that the ratchet is angled after being fixed to the rear wheel hub, which will deteriorate the part and the hub itself over time.
- Best in urban use
- Maximum 7 speeds
- Angled fixation
What is the difference between ratchet and cassette?
It is practically certain that, in your research, you will come across the ratchet and cassette question, which one is better, which one to use, which one to buy, anyway.
Both are variations of the same piece.
Ratchet and cassette are basically two variations of the same piece. The function is the same, but the operation and design are completely different.
The fundamental distinction between the two is the position where the free wheel is located, the part rotates freely and transfers the energy from the pedal to the system – which makes the wheel rotate.
In the ratchet, the free wheel is inside the piece, which is then screwed into the hub, the connecting piece between the ratchet and the wheel; in the cassette, the free wheel is located in the hub itself, which is fitted to the piece, by means of grooves compatible with the grooves of the piece.
|Free wheel||In the play||In the cube|
|Installation||Threaded on the cube||Docked|
|Strong point||Resistance and price||Greater durability and practicality in maintenance|
Purchase Criteria: What to note on your bicycle turnstile
For you to be concerned only with what matters, like, well, your cycling, we have made a list to guide your entire selection process, so that you can finalize your purchase by paying for the best ratchet for your bike.
One of the most useful and easiest information to identify on a bicycle ratchet is its tooth ratio. Generally speaking, the more teeth there are in the ratchet, the smoother the gears will engage and pedal as a whole.
You will probably find, especially on the internet, information like “teeth ratio”, and a double number, like 11-32, or 11-34. This relationship speaks of the number of ratchet and crown teeth, always with the number of the ratchet in the front.
The number of speeds of a ratchet is easily identifiable information, and very useful for comparing and selecting your ideal model.
The number of speeds is proportional to the number of gears.
Explaining more simply, the number of speeds is proportional (but not equal) to the number of gears. Although it depends on the number of crowns on the crank (which is quite easy to find out) to determine exactly the number of gears, the rule remains valid.
This criterion serves more as a reminder, to choose the ratchet model best suited to the rim, in this case the size of the rim, of your bicycle.
There are no specific models for a certain rim size, but it is possible to find a more compatible model, in the logic that larger hoops require greater pedaling strength, and therefore larger ratchets, with more teeth and speeds.
A very practical way to choose quality bicycle turnstiles, even more if you are a layman, is to go after the quality brands.
We recommend three brands, Campagnolo , Sram and especially Shimano , the most “famous” of the three. There are three manufacturers with a lot of tradition in this market, and with catalogs full of models and varieties to meet the most specific types of bicycles and rides.
