Bicycle rear sprocket

A bicycle is a means of transportation, driven by the physical strength of a person. This is how you can describe the essence in technical words. In fact, he is a friend from childhood. As soon as we begin to grow up and understand something, we drag our parents to where we can choose a bike and shouting: Buy !!, in the end we proudly roll home a new product, while we still do not suspect that any equipment needs care and that it can break. Even an old bike can still serve.

Most common question about bike maintenance and rear hub (excluding device, ratchet and sprockets). How to remove sprocket from the rear wheel of a speed bike?

It often happens that the hub needs lubrication or the rear wheel sprockets need to be replaced. The repair process is easier if the cassette is removed. Thus, things will go faster and more accurately.

How to remove a ratchet from a bicycle wheel?

In order to adjust the bearings on the rear hub, in order to replace a worn sprocket, and sometimes to replace a broken spokes in the rear wheel, it is necessary to remove the cassette with sprockets. This is not so difficult to do. By and large, the algorithm of actions is the same as with a separate asterisk.

When you need to replace your rear bicycle sprocket

An inexperienced user may confuse a sprocket and a ratchet, but the difference is that the cassette stars have a minimum diameter of 11T, while the ratchet has a minimum diameter of 14T. To replace the rear sprockets of the bike, you must remove the entire cassette completely.

The ratchet of the rear wheel of the bicycle has several driven stars, which are connected by a freewheel hub. The ratchet is considered not a very durable and reliable component; axle breakages often occur due to design imperfections. The ratchet can be removed for repairs in the same way as the cassette.

The efficiency and functionality of the bike depends on the rear wheel hub. The part has several components. If the stroke is heavy, then there is probably a problem and the cone is damaged. To eliminate malfunctions, unscrew the nuts with a wrench and remove the wheel.

When regularly inspecting the technical condition of the transport, pay attention to the bushing taper, clean and lubricate parts and bearings. This detail is very important, it organizes the transmission of the transmission to the wheel from the pedals, as well as several other important tasks.

How to remove the rear sprocket?

  • puller;
  • whip;
  • key of the right size.

First of all, remove the wheel. Turn the bike upside down with the wheels and unscrew the nut on the axle with a wrench. In some cases, for example, a sports bike or mountain bike, you need an eccentric clamp. Simple models do not require a special approach and tool.

The rear sprockets are attached to the ratchet with a special nut (slotted). This very nut must be unscrewed with a puller and a wrench. The latter must be appropriate in size. Unscrew the nut clockwise and use the whip. Requires to insert the puller into the spline nut in the rear sprocket of the bike.

We carefully put the whip on a large diameter sprocket. Holding the cassette, we rotate the puller with the key. This requires some effort. After unscrewing the nut, remove the cassette. The rear sprockets of the bike can be positioned independently of each other on the ratchet. It is required to remove all parts, small sprockets, washers, carefully and carefully. This is to avoid confusion of elements. Then the cassette and plastic ring are removed. After completing the replacement of worn parts, all components, including the sprockets, are assembled in order.

The nut is tightened with a wrench and with the application of maximum efforts, but the main thing is not to overdo it and tighten the bushing cone not too much.

Sleeve

Disassembly and diagnostics of this part is carried out after separation of the cassette. It is best to start the process on the left side. Next, the boot, locknut and cone are removed. Then you can find washers, the number of which depends on the type of bike.

It is very important to remember exactly the location and order of finding all the parts. Now the stage begins in which the cone is gently unwound. If the grease is in poor condition, it is necessary to remove the bearings and inspect them. The presence of rust, dirt and other troubles indicates the replacement of parts.

With this option, good parts need to be put in place before lubrication. With a careful approach to work, the bike will function properly and accurately. Removing the bushing and other parts is not difficult, but it is important to remember the order in which they are located.

Installing the rear sprocket on a motorized bicycle

We remove the asterisk ourselves

Turn the bike over and place it on the handlebar and saddle.

First of all, remove the wheel by unscrewing the fastening nuts.

Children’s bicycles are usually repaired, as a rule, by dads, and they have enough strength to fix the largest sprocket with a whip and put a wrench on the puller to unscrew the spline nut. Everything is unscrewed towards the idling wheel and at the same time a small crunching sound is heard, do not be alarmed, this is due to the shape of a small asterisk.

By unscrewing the nut, remove the cassette, taking into account that there may be intermediate washers between the small sprockets, instead of gaskets. To replace the sprocket you need a set of tools.

When disassembling this entire structure, carefully fold all the parts so that they lie in the sequence in which you removed them, otherwise difficulties will arise during assembly.

After removing all the sprockets and the cassette, the protective plastic ring is removed last. Inspect all removed parts carefully, replace worn ones, clean and lubricate so that after assembly the assembly runs for a long time.

The assembly of the sprocket cassette is carried out in the reverse order. The chain is put on, the rear wheel is spun, the device turns over and it is again ready to surf the roads bringing joy and pleasure from the movement.

Varieties of bicycle cassettes

A set of rear sprockets on a bicycle is called a cassette. Cassettes are available in 6, 7, 8, 9, 10, 11, 12 speeds. The cassette with 6 speeds is put on children’s bicycles, 7 speed, on budget, walking bicycles. Cassette with 8 sprockets, matches the 24 speed transmissions found on mid-range bicycles, 9-12 speeds on mountain and racing, sports bikes.

A large number of stars allows you to adjust the gear ratio, for more comfortable pedaling, the smaller the chainring, the greater the rider’s speed. If the switch is set to a large star, then you can easily climb the hill.

A set of sprockets for 6-7 is in the form of a ratchet, which is screwed onto the bushing and cassettes, which is put on the bushing drum and fixed with a nut. I change the cassette when obvious tooth wear is visible and the chain slips.

What makes you ride a big sprocket or small sprocket faster on a bmx bike?

First you need to clearly understand what you are talking about In normal bike conversation, the sprockets go behind, and on the front wheels there are sprockets / sprockets In BMX talk, the sprocket goes in front, and the driver goes back If you say BMX, the most the obvious difference is size, number of teeth For the same size driver, a larger sprocketwill makes the bike slower from the start, but gives it a higher speed For the same size rider, a smaller sprocketwill makes the bike faster from the start, but give it more low speed If you change the driver to match, the starting and maximum speeds will be the same, even with a smaller / larger sprocket The small sprocket will increase the ground clearance.

assemble, rear, sprocket, bike

Better if you are riding races as there is less chance of sprocket / lip grip when you enter Unless you are riding ramps, well, the smaller sprocket is even lighter, which is kind of an advantage. The downside is that the less they get, the faster they wear. And wear chain. Changing to a smaller sprocket at the back will make your bike heavier to pedal.

If you are strong enough to keep spinning at the same speed as before, your bike will be faster.

What is the best sprocket on a bmx bike?

Ask for the best size star. it’s like asking for the best shoe size. you get the one that suits you, or in this case. your riding. Do you want to go faster but can’t turn the cranks faster? Get less. Do you feel it is difficult to get the bike to move? Get more.

I need 9 toothed sprockets on my BMX motorcycle for the back, I need a driver, or can I just put on a freewheel and what I need to know about installing it, I know about the chain?

You can get a 9 toothed sprocket, for that you need a conversion kit. Haro does decent, just scour Haro 9/25.

Is it better to have a smaller sprocket on a BMX bike?

The smaller the sprocket, the lighter the sprocket and the shorter the chain. The shorter the chain, the lighter the chain. Remember to reduce your reverse gear when you use the smaller front chain or you will spin like crazy. For example: Typical setting. 44 front and 16 rear.

If you put a chain of 38 teeth in the front, make sure the back sprocket is reduced to 14. Basically, you take the number of front teeth and divide in the back. Simply. The ideal BMX gear ratio is 2.75, but different people have different preferences.

What’s a tiny bike with a tiny rear wheel?

You’re probably thinking of the AWD, AKA Penny-Farthing, which had a huge front wheel and a small rear wheel.

What is the name of the rear sprocket on your bike?

What is a spiral sprocket?

Each small piece that sits between the chain link is called a tooth, so treat the teeth on it like a star. Fixed gears or free types are available and they connect to the rear hub on the wheel.

Can you put a mountain bike sprocket on a bmx bike?

Probably no. BMX bikes usually have freewheels, while MTBs usually have freehubs and don’t mix. However, you can use single speed MTB parts on BMX.

Change the sprockets on the rear wheel of the bike

The drivetrain plays a very important role in the operation of the entire bike, so you must carefully monitor the wear of individual parts of it. This is especially true for the rear wheel sprockets, which fail over time. A worn out sprocket must be replaced as soon as possible, and it will not be difficult to do this.

Before starting the replacement process, get yourself the tools you need to help you. It:

  • Whip
  • Cassette remover
  • Rozhkova and adjustable wrenches

First, remove the rear wheel from the bike. This is very easy to do. Unscrew the nut with a wrench and release the chain. Owners of mountain models just need to press on the special mount and the wheel will be dismantled. Next, we install a removable device on the slotted nut of the cassette. Here we need a whip to prevent the cassette from turning. While we rotate the puller with an adjustable wrench, hold the largest star with a whip.

Using a nut, unscrew the cassette and remove it from the wheel. We carefully examine the stars and determine which one has become unusable. Start with the smallest and end with the largest. The bike drivetrain is designed in such a way that you can only replace the worn out sprockets and not the entire cassette. Therefore, having inspected the cassette, you remove the used parts from it and replace them with new ones. It is very easy to pull the star out of the cassette, this is facilitated by special rivets. The main thing is to carefully remember the order of the stars, so as not to get confused with their installation back. In the configuration of some bikes, you may find so-called spiders. It is a group of several stars that are inextricably linked. In this case, you will have to replace the entire spider. Many cyclists are faced with the following problem. After replacing several stars, there is great discomfort in the operation of the chain. This is due to the fact that the chain has already passed a certain mileage, has worn out and now it is difficult for it to interact with new parts. Therefore, experts recommend the simultaneous replacement of the chain and worn sprockets. This greatly minimizes the complexity of your bike’s drivetrain.

If you own a single speed bike, the process of replacing the chainring will be simplified to a minimum. You just need to open the retaining ring. If your own ring has become unusable, it must be replaced immediately, even if you are not going to replace the stars in the near future. Otherwise, the chain will lose its fixation, and this threatens with backlash. The process of replacing the ring is very simple, you do not need to perform the slightest forceful manipulations. Therefore, if you are talking about a single-speed bike, everything is very easy and understandable here. However, the owners of such models should carry out the process of dismantling the cassette only if one or more of the largest stars have worn out. If a small asterisk starts to fail, this is not a cause for concern. Whatever you ride, remember that both the simplest road bike and the super-fast bike need a proper transmission. A badly worn chain and stars will not allow you to drive even a couple of meters. Pay close attention to the mechanics and replace worn-out parts in a timely manner. A working bike is the main guarantee of your safety and a cool, trouble-free ride!

Dismantling the transmission cassette

The rear of the transmission is not too difficult to disassemble, all that is needed is time and a few tools: a cassette puller, a whip and wrenches (open-end. for removing a wheel and an adjustable. for a cassette).

The first thing to do is to free the bike from the rear wheel. Using a wrench, the nuts are unscrewed, and the chain is dropped from the rear sprockets. On a mountain bike, it is usually a matter of a second to remove and put on the wheel, thanks to the eccentric fastening.

The removable device is installed on the slotted nut of the cassette. A whip. a small flat knife with a fragment of a chain. is needed to keep the cassette from turning. With the help of an adjustable wrench, we rotate the puller, we direct the whip in the opposite direction, or, more simply, we hold it with a large star of the system.

To unscrew the nut, you will need to sweat a little, and not only in the first stage. With the same good effort, the stars will need to be returned to their place. Once the nut has folded, the cassette can be safely unhooked from the wheel. Now it remains to examine it and determine which star needs to be pulled out.

Some of the outer small sprockets can be removed immediately when removing the cassette. They should be cleaned and inspected for wear. The same is done with the main sprockets: it is determined how much they are worn out and which ones are the most.

Removing and installing a star on cassettes

Unlike ratchets, in this system the stars can be changed individually. All that is needed is to remove the old part and put a new one in its place. Special rivets and small spacers are located between the stars, which allow them to hold a fixed position and facilitate the installation of the cassette itself. It is very easy to screw the desired star from the device, the main thing is not to get confused in the sequence, especially on large cassettes of high-speed mountain bikes.

Sometimes spiders can be found on cassettes. rigidly fixed areas of several stars. Here you will have to replace the entire set, on which one of the stars is badly worn out. True, this only applies to large transmission rear wheel sprockets.

When replacing a single chainring, you may encounter the problem of the difficulty of switching the chain to it. This is due to the fact that the chain already has wear compared to the new sprocket. And if this is not so noticeable with one detail, then several new stars will immediately bring a tangible dissonance to the operation of the transmission. That is why it is advisable to change the cassette at the same time as the chain.

How to remove the bike cassette

Cyclists often have to service their vehicle on their own. each time it will be quite expensive to contact specialized repair services. Many bicycle elements can be removed and installed quite easily and simply, but there are details that require the use of specific tools and some knowledge. These include the cassette. a part that is attached to the rear hub.

Stages of installing new stars

How does assembly work when replacing a bicycle cassette chainring?

  • Install a new sprocket and fix it.
  • We assemble the cassette completely in the reverse order.
  • Using a puller, mount the drum to the slotted area.
  • The drum must first be leveled.
  • Next, we carry out the process of assembling the bushing. All actions described in the first paragraph are carried out in reverse order.
  • Install the rear wheel and fix it securely.
  • Put on the chain.

It is imperative to check the smooth operation of the transmission. This procedure involves adjusting the rear derailleur.

If everything is carried out according to the proposed instructions, feel free to get on the bike and enjoy the ride.

How to remove the bike cassette

First of all, you need to prepare the necessary tool:

  • cassette retaining ring remover;
  • whip. a special key to which a bicycle chain is attached (fragment);
  • adjustable wrench.

You can, of course, do without the specified specific tool. over, there are 2 such methods and both will work 100%:

Be sure to prepare an area with a flat surface, which should be within arm’s reach of the bike. this is how you can save and not lose all the parts of the bike cassette.

Step-by-step instructions for removing the cassette:

  • The bicycle wheel is removed, a special puller is installed. You need to pay attention to the correct installation of this tool: its slots must completely enter the grooves of the retaining ring.
  • A whip is taken in your hands, put on the sprocket in such a way that the fragment of the bicycle chain on the key is on the teeth of the sprocket. Please note that the whip handle should be to the right of the cassette, a fragment of the tool chain. at the top.
  • An adjustable wrench is placed on the cassette remover and rotated counterclockwise. Simultaneously with this movement, it is necessary to firmly hold the whip key in the fixed position. thus, the movement / scrolling of the sprocket is blocked. Note:in some cases, the chain may jump off during this process, which means a strong wear of the cassette sprockets or a broken key whip. Experts recommend putting a whip on a large sprocket. you can get the desired fixation effect.
  • The retaining ring is completely unscrewed, the cassette is removed.

Be sure to make sure that the removed cassette, as well as the sprockets and all fasteners, are in the removable form exactly in the order in which they were in the original version.

After removing the cassette, you can start cleaning and lubricating it. these procedures are among the mandatory for regular maintenance of a two-wheeled vehicle.

Star stripping process

How to change the rear sprocket on a bike after the first stage has already been passed.

  • Removing the mount.
  • Detach the cassette from the rear wheel.
  • We make a thorough inspection.
  • Determining Wear Sprockets.
  • We remove the worn out product.
  • Pay attention to the arrangement of the stars and the sequence of fasteners and washers between them.

Cassettes compare favorably with ratchets in that each worn part can be freely removed separately.

A separate recommendation would be to replace the chain, which is also worn out, along with the sprocket.

Removing and installing a star on cassettes

Unlike ratchets, in this system the stars can be changed individually. All that is needed is to remove the old part and put a new one in its place.

How to remove rear sprockets from a bike

The bike drivetrain requires periodic maintenance. The most common problems are chain wear and failure of one or more sprockets on the cassette. Wear is also true for a single-speed one, the only difference is that the chain and the star itself are designed for longer operation.

The worn out part of the transmission negatively affects its entire operation, therefore the used sprocket will need to be replaced. Especially this problem pops up on asterisks, which are used too often, which, in principle, is logical. Before changing, it is necessary to remove the worn out sprocket from the rear wheel, which we will talk about further.

Disassembly process of the transmission cassette

Some theory beforehand. On the rear wheel there can be two variants of parts related to gear shifting.

  • Transmission cassette. This product features modernity and innovative spline mountings that attach to the hub axle.
  • Ratchet. A somewhat outdated model typical of inexpensive speed bikes. There are no more than seven gears in a set. As for the mount, it has a thread with external installation parameters.

Let’s focus on the ratchet right away. Changing the rear sprocket on a ratchet bike is not possible. Only change the entire component completely.

Therefore, the topic of the article will be a problem describing a situation when a bicycle cassette star needs to be replaced. As for the set of stars in the transmission, up to 11 pieces are possible, depending on the bike model.

So how do you change the rear sprocket on a speed bike? Consider the algorithm of actions.

  • Take the bicycle wrench for the rear wheel and dismantle it. We sequentially unclench the levers and loosen the fixing of the nut.
  • Now it is the turn for the axle nuts. Using another key, turn off the mount.
  • The next step involves unscrewing the bearing cone and pulling it out.
  • We take out the axis with all the elements.
  • We take a special tool. a cassette remover. We insert it into the slots.
  • The whip is placed on the largest sprocket. We make rotational movements clockwise.
  • At the same time, using an adjustable wrench, the puller rotates in the opposite direction.

The preliminary stage is over. Such simple actions are possible in ordinary household conditions. We emphasize that if more than one star is worn out, but several, then it is better to replace the entire cassette at once. This option is also desirable when the largest star is damaged.

And one more recommendation. We put all small parts, washers and nuts in a certain place, so that later we do not search all over the room

A little about singlespeed

To remove the rear transmission sprocket from a single speed bike, you only need to open the retaining ring. Among singspeed lovers, you can hear that the regular ring is useless and can break itself, even if you did not think about changing the star. Perhaps this is so. In any case, if the stopper is damaged, we change it to a new one, otherwise backlash cannot be avoided (the chain simply dangles from side to side).

It is also very simple to assemble such a structure: the ring is literally put on its own, you don’t even need to squeeze it. It’s that simple on single-speed bikes! You shouldn’t just wedge yourself into the transmission of a bicycle with one gear. Common reasons are a badly worn part or the need to install a new sprocket with a larger diameter.

As you know, without serviceable stars and chains, a great cannot even move. Timely replacement of transmission system components is an essential part of repairing any type of bike. from simple two-wheeled road bugs to road and mountain superbikes.

How to remove rear sprockets from a bike

  • Bicycle, new rear wheel, tool kit

If you decide to replace the rear wheel of your bike, decide which brakes are installed. The sequence of your actions depends on this.

If the brakes are disc brakes, no special operations are required. But the rim brakes will need to be released first. If this is not done, then you simply cannot remove the rear wheel.

If your bike has V-BRAKE brakes, start by squeezing the pads. This will make it possible to remove the arc. It is necessary to squeeze at the point of attachment of the cable. To perform this operation, special efforts are not required.

Turn the bike upside down by placing it on the handlebar and saddle. Beforehand, you should remove the navigator, travel computer or other valuable equipment.

Before carrying out work, you need to take care of the gearshift knob and the brake lever. Place a soft cloth underneath. This will protect the devices from damage.

If a hydraulic brake is installed, do not keep the bike upside-down for a long time. It is possible that you will take a long time to change the wheel. Remember that air can enter the hydraulics. If this happens, you need to bleed the brakes.

The cleaning procedure for hydraulic brakes is quite time consuming. Of course, you don’t need to bleed the brakes, but then they will not work properly. This cannot be allowed.

The rear wheel of the bicycle is fixed to the axle. There are different mounts, the sequence of your actions depends on its type. If the mount is wrench, a pair of wrenches are required to work. Tighten the nut, unscrew the second with another wrench.

It is not necessary to completely unscrew the nut. Turn the key a few turns. After that, the wheel can be removed quite easily.

If we talk about the eccentric, then removing the wheel will be even easier. You just need to unscrew its lever. After that, you need to twist it counterclockwise. You can remove the wheel.

assemble, rear, sprocket, bike

Be aware of the chain running through the bike’s gearshift system. Carefully remove it from the sprockets, leaving it against the frame.

Grasp the wheel and pull it up, it will come out effortlessly. Pay attention to the next point. If your bike has disc brakes, you do not need to press the handle with the wheel removed. The fact is that such manipulations lead to compression of the pads.

Loosen the pads. Only after that start installing the wheel. Reverse the steps when putting the rear wheel back in place.

Change the sprockets on the rear wheel of the bike

The drivetrain plays a very important role in the operation of the entire bike, so you must carefully monitor the wear of individual parts of it. This is especially true for the rear wheel sprockets, which fail over time. A worn out sprocket must be replaced as soon as possible, and it will not be difficult to do this.

Before starting the replacement process, get yourself the tools you need to help you. It:

  • Whip
  • Cassette remover
  • Rozhkova and adjustable wrenches

First, remove the rear wheel from the bike. This is very easy to do. Unscrew the nut with a wrench and release the chain. Owners of mountain models just need to press on the special mount and the wheel will be dismantled. Next, we install a removable device on the slotted nut of the cassette. Here we need a whip to prevent the cassette from turning. While we rotate the puller with an adjustable wrench, hold the largest star with a whip.

Using a nut, unscrew the cassette and remove it from the wheel. We carefully examine the stars and determine which one has become unusable. Start with the smallest and end with the largest. The bike drivetrain is designed in such a way that you can only replace the worn out sprockets and not the entire cassette. Therefore, having inspected the cassette, you remove the used parts from it and replace them with new ones. It is very easy to pull the star out of the cassette, this is facilitated by special rivets.

It is a group of several stars that are inextricably linked. In this case, you will have to replace the entire spider.

How To Overhaul A Bicycle Single Speed Freewheel

Many cyclists are faced with the following problem. After replacing several stars, there is great discomfort in the operation of the chain. This is due to the fact that the chain has already passed a certain mileage, has worn out and now it is difficult for it to interact with new parts.
