How to remove?
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.
Bicycle rear sprocket
Bicycle rear hub: device, ratchet. How to remove a 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 to carry out with remove the cassette. This way things will go faster and more accurately. Of the tools you need:
An inexperienced user may confuse these two parts, but their 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.
Remove the sleeve
Removal of this part is done after detaching 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.
How to remove a ratchet from a bicycle wheel? To do this, it is better to use a special puller key.
How To Replace Your Cassette | MTB Tech
How to remove the rear wheel of a bike.
In theory, all riders and cyclists know how to remove the rear wheel of a bicycle. And here’s what to do in conditions close to combat, when 35 minutes are left before the train departure, and the rear wheel is lowered 10 kilometers from the station. I advise you, dear colleagues and readers, to always carry with you, in addition to a gentleman’s set of hexagons, edgers, teflon, a pump and a spare chamber, a cloth and a package of wet wipes. Believe me, it is much more pleasant to hold the wheel of a bicycle with clean hands than with dirty hands. So, you have an urgent need to remove the rear wheel of your bike. First, place the chain over the smallest sprocket on the rear wheel. Remove anything from the steering wheel that might break when you put the bike upside down. Remove the backpack from the trunk, if there is one, of course. Disengage the rear brake if you have rim brakes (V-brakes). If you are big and strong, just place the bike upside down. If you are more fragile, do it in two steps: first place the bike on the left roll, then grab the frame and front fork and turn it upside down. Open and loosen the eccentric or unscrew the fastening nuts, make sure that the wheel is running (perhaps the released brakes will not be enough, you will have to release the pressure in the chamber). Using a cloth, grasp the rear derailleur by the frame, pull the chain back to free the sprockets; with the other hand, pull the wheel out of the dropouts. the lugs of the rear stays. After you have done all the necessary manipulations with the removed wheel, it must be returned to its native rear triangle. We insert the wheel between the feathers, while the sprockets should be inside the chain ring. Gently (again, through a rag) tilt the switch frame to the steering wheel so that the chain looses and the wheel falls into the dropouts; at the same time, we make sure that the chain wraps around the small sprocket of the gear block, and then goes into the switch frame (you can just push the wheel, but the first time it is not always possible to find the desired angle). If you have disc brakes, check that the disc fits into the caliper slot (a device that, when you press the brake lever, grips the disc with the brake pads). Make sure the wheel axle on both sides is fully engaged in the dropouts. Make sure the chain is in the correct position. Spin the pedals; if you notice that the wheel is rubbing against the frame, correct the skew. Tighten the nuts, close the eccentric. Flip the bike over, engage the brakes, make sure the pads are in the correct alignment with the rim and grip the rim firmly. If necessary, pump up the wheel, adjust the position of the brake pads. You can collect the tool, hang a backpack, fix the removed bells and whistles on the steering wheel and set off. If you are not interested in how to remove the front wheel of a bicycle, you can skip reading. But believe me, removing the front wheel of a bicycle yourself is no less exciting than the rear one. The principle is similar. remove, unfasten, turn over, open, loosen, deflate; doing the reverse doesn’t involve fiddling with the chain. The front wheel can be removed and installed while the bike is lying on its side. Be sure to check the engagement of the axle in the dropouts and the operation of the brakes! The main thing is not to forget to wipe your hands later! Why are you carrying this incredible weight with you. a package of wet wipes.

Mountain Bike Drivetrain (All Mountain)
The All Mountain drivetrain features a single chainring sprocket, combined with an 11 chainring at the rear. This makes the bike easy to operate, fast and functional at the same time.
It is possible to determine the optimal settings by trial and error, taking into account your own riding style, the size of the bike’s wheels and a number of other factors.
How to remove the rear sprocket on a speed bike without a puller. How to remove the sprockets from the rear wheel of a bicycle: step by step instructions
How to remove sprockets from the rear wheel of a bicycle without a puller?
For such an operation, you do not need to purchase a special tool. True, it is much easier to deal with him. In order to remove the ratchet without a puller, you will need:
- gas wrench;
- center punch;
- a hammer.
The ratchet has 2 slots. You need to insert a center punch there and hit it with a hammer. You need to direct it clockwise. You can use a large nail instead. You have to be careful, as there are bearings under this place. With a little effort, you can screw the sprockets.
There is still the inside of the ratchet. It is removed with a gas wrench, which is turned counterclockwise.
Sprockets are important transmission parts. For the bike to function normally, you need: the correct choice of gears, careful and timely maintenance, replacement of worn parts. All this allows us to make trips safer, to avoid unpleasant surprises on the road. As for the high-speed bike, it will really show itself to be high-speed, and will not sadly drag on a single gear.
How to remove a sprocket from a single speed bike (singlespeed)
To remove the transmission sprocket on a single speed bike, simply open the circlip. Many singlespeed fans argue that the native retaining ring is worthless and sometimes breaks, even if the question is not about replacing the star. In any situation, if the stopper is out of order, you need to replace it. Otherwise, backlash is inevitable. The chain will simply dangle in different directions.
If the sprockets are defective, the bike will not ride. Timely replacement of transmission parts is important for all models of bikes: from the simplest hard workers to the most sophisticated high-speed highways and mountain bikes.
Disassembly procedure for transmission cassette
Removing the rear of the transmission is easy. Sprocket Removal Tool Kit Next.
- Open-end wrench for wheel dismantling;
- Adjustable cassette wrench;
- Cassette remover.
The first step is to dismantle the rear wheel of the bike. Using a wrench, unscrew the nuts, then remove the chain from the rear sprockets. For some modifications (for example, for MTB), removing the wheel is literally a matter of a minute, since it is attached to the eccentric.
Install the puller onto the spline nut. The whip is used to keep the cassette from spinning. Use an adjustable wrench to rotate the puller. The direction of rotation of the whip is in the opposite direction.
Removing the nut is not easy. You will also have to work hard to install it in place. After the nut has been unscrewed, the cassette is detached from the wheel without effort. It remains only to assess the condition of the cassette and determine which sprocket is out of order.
The outer sprockets can be removed immediately after the bicycle cassette has been removed. They are cleaned and carefully examined to assess the degree of wear. Worn out. replace.
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 noticeable dissonance to the operation of the transmission. That is why it is advisable to change the cassette at the same time as the chain.
Shimano Cassette Removal. Easy How-To. Origin8 Classique Pro Bicycle Tools
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.
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.
How to install a cassette on a bike
First of all, make sure that the cassette assembly matches the unfolded / removed parts. To facilitate this process, the sprockets have grooves of different sizes (for each sprocket. individual), and the bushing has suitable splines. It is the correct alignment of the grooves and splines that all the sprockets will stand in a certain order.
There are some important things to keep in mind when installing the cassette on your bike:
- Many cyclists lubricate the bushing surface before installing the part in question. However, experts believe this is wrong. after lubrication (until the entire cassette is assembled and installed), both dust and dirt will have time to get onto the applied lubricant, which ultimately leads to the need for maintenance, repair or replacement of elements.
- Experienced cyclists lubricate the thread of the retaining ring before assembling the cassette. during subsequent disassembly it will be much easier to unscrew.
- All sprockets must be worn alternately, but do not forget to put spacer rings between them. In some bike models, you can see not separate sprockets, but a single / one-piece assembly.
- In many bicycles, to securely install the last sprocket, you need to press it slightly and only then you can screw the retaining ring.
- After the locking ring is screwed in, first you need to check the correct installation of the cassette and only then can it be finally tightened. Tightens the retaining ring clockwise.
Removing and installing the cassette is not difficult, because if you have a minimum set of tools and at least basic knowledge of the technical plan, all the work will take a little time, a maximum of 60 minutes. But even if such a process is to be carried out for the first time, you should not give up. the experience of removing and installing a cassette will certainly come in handy more than once. The fact is that experienced cyclists recommend carrying out such maintenance of the bicycle cassette at least once a year.
How to remove a cassette
Remove the bicycle wheel, then install the puller so that its splines fully enter the grooves of the retaining ring.
Place the whip on the sprocket so that the links of its chain sit tightly on its teeth. The whip handle should be to the right of the cassette and the chain on top.
Put the adjustable wrench on the cassette remover and turn it counterclockwise, while you need to hold the handle of the whip without letting the stars spin.
If the chain slips off, it is possible that the cassette stars are badly worn, or the whip is faulty. In this case, try to put it on a big star.
Unscrew the retaining ring to the end, then remove and unfold the stars and spacers. Lay out everything in order so that nothing is confused during assembly.
The cassette is removed, now it can be cleaned or changed.
How to install a cassette
When installing the cassette, the main thing is not to mix up the order of installing the parts. In order to properly install the sprockets, they have grooves with different widths, and on the hub there are the same splines, thanks to them the teeth will fit in the right order.
Some cyclists advise lubricating the hub surface before installing the cassette, but I think that would be superfluous. First, the chance of corrosion is too low. Second, the friction between the hub and the sprocket is also not high enough to cause damage. Thirdly, dust and sand can adhere to the lubricant, which can lead to accelerated wear of parts.
Apply grease only to the thread of the retaining ring, then it will be easier to unscrew it next time.
Put on the stars in turn, but do not forget about the spacer rings. In some cassettes, all or several stars can be connected into one non-collapsible unit. “spider”. But more often than not, all the stars go separately.
In some cassettes, to install the last asterisk, you must click on it. Check again if everything is installed correctly, press the last sprocket with one hand, and screw the retaining ring with the other hand.
Tighten the ring all the way, but do not tighten yet. Check again that all the stars are parallel to each other, and that they are straight. If something confuses you, disassemble the cassette and fix the malfunction.
If you are sure that everything is assembled correctly, then take the cassette remover and tighten the locking ring clockwise to the end.
Everything, the cassette is assembled. Once again inspect the correct assembly and you can put the wheel in place.
