How to make a sprocket on a speed bike

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.

How to Make Your Own Chain Sprocket DIY

how to replace the rear sprocket on a speed bike

There are not many key parts to a speed bike. The main ones include the stars, which serve to switch speeds with the provision of gear ratios in the transmission. With the constant operation of the bicycle mechanism, worn sprockets are formed. This is facilitated by the usual physical process. friction. What is the threat? The chain starts to jam and simply slips deformed parts.

The problem that has arisen requires an immediate solution. If the question is ignored, then any movement on the road will turn into a solid negative. The model of a modern bike allows you to change a worn out part. Our article will tell you how to replace the rear sprocket on a speed or mountain bike.

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 A somewhat outdated model typical of inexpensive speed bikes. The set contains no more than seven gears. As for the mount, it has a thread with external installation parameters.

Let’s focus on the ratchet right away. Changing the rear chainring 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

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 and put a system star

The system is a set of three chainrings. If you often have to ride at speed, then most likely the largest sprocket will wear out. Conversely, with frequent off-road trips, wear will affect the first (smallest) sprocket. By analogy with the second, middle sprocket, when the bike is used at medium speeds in conditions of a dirt road or bad asphalt.

On a modern mountain or road bike, the system is collapsible, so it will not be difficult to dismantle all the stars. Before work, you need to carefully prepare, namely, collect all the necessary tools:

Removing the system from the bike: 1. Place the frame in an upright position. If you have a stand, you should definitely use it.

Remove the right crankshaft axle fixing bolt with a hexagon.

Unscrew the pedal from the right crank arm. A standard open-end wrench is suitable for this.

Insert the puller into the connecting rod to remove it from the carriage. To begin with, we screw the tool all the way into the thread. It is important that it sits flat on the shaft, otherwise the axle can be damaged when unscrewing the connecting rod. Place the spanner wrench on the puller and screw it in until it stops until the connecting rod is pushed out of the carriage shaft.

The two stars are usually attached to each other on a so-called spider. The big one remains on the connecting rod itself. Unscrew them with the hex bolts.

This is how the system understands. Replacing and installing looks like the reverse process:

  • Install the desired sprocket on the spider and tighten the fasteners. Change the large part together with the right connecting rod and screw the medium and small sprockets onto it.
  • Next is the installation of the connecting rod on the carriage. Before this, it is advisable to clean and lubricate the carriage shaft.
  • Carefully place the chain on the system and screw in the connecting rod by rotating the puller in the opposite direction.
  • Tighten the fixing nuts and fit the plugs.
  • Screw the pedal onto the connecting rod.

When replacing one star, it is advisable to clean the old ones. Lightly grease the system components before installing on the carriage.

So just replace the chainring. All of the listed tools are required. The connecting rod is a delicate thing, and a hammer and chisel is not the best option for removing it. The same goes for keys. It is difficult to replace them with pliers, besides, the nuts can easily “eat”. Well, without hexagons, it is impossible to disassemble the system into parts.

At the end, check the operation of the transmission. whether everything is in order and whether it is necessary to adjust the speed switch.

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 use. 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 examined 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 rear 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 begins 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 promptly replace worn-out parts. A working bike is the main guarantee of your safety and a cool, trouble-free ride!

How to remove the bike cassette

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

Making a sprocket for bicycle chain the way Clickspring wouldn’t

  • 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.
  • The “whip” key is taken into your hands and placed on the sprocket in such a way that the fragment of the bicycle chain on the key is on the sprocket teeth. Pay attention to the fact that the handle of the “whip” 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 a 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 breakage of the “whip” key. Experts recommend to put 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 a sprocket from a bike

The sprockets of a speed bike are the main parts of the gearshift system that provide the gear ratio of the drivetrain. According to the degree of influence, they are divided into leaders and followers. The first are located at the connecting rod pair and are called the system. The driven ones are located on the rear wheel hub and are divided into cassettes and ratchets by design.

Over time, the stars wear out, as a result of which they need to be completely or partially replaced. The second option is more common in practice, since the wear is uneven. The most frequently used transmissions are subject to it. The problem, of course, requires a timely solution, otherwise driving will turn into torment. The chain will seize or skip over worn sprockets. Many modern models allow you to remove the sprocket and put it separately on the system or cassette without replacing the entire assembly. Read on how to do this.

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.

We wash the insides twice.

Put on your safety goggles, take a can of GT85 or WD-40 and spray a continuous layer on the inside of the freewheel hub. Then pour plenty of machine oil over the parts, let it drain, wipe dry and repeat the operation. Then install the gasket, lubricate the joint and put the freewheel back in place.

We remove the cassette.

Remove the rear wheel and secure the cassette with the “whip”. Wrap the “whip” around the third star clockwise or larger (so that the longest piece of whip is wrapped around the star). Insert the circlip remover and wrench so that its key handle is to the left of the whip handle, but close enough to be grasped with both hands at the same time. Now squeeze and unscrew the retaining ring and cassette firmly. The distance between the circlip and the locknut on the axle may not be sufficient to accommodate some brands of tools, but Shimano or Park pullers always work.

How to disassemble and lubricate the cassette hub

Water and dirt can easily get inside the cassette hub and if this happens, your bike will clang and screech like an old elevator.

To disassemble and clean the bushing, you need special tools and a little additional knowledge on how to do it correctly. In this guide, we will walk you through and show the whole process step by step. But if you doubt the correctness of your actions, especially in the third step, it is better to entrust this to a specialist.

Campag bushings.

The new Campagnolo Centaur, Chorus and Record hubs are disassembled differently. Fix the axle on the left side with a 5mm socket wrench. Then, using a 17mm open-end wrench, turn the lock nut on the right side clockwise and unscrew it. In order to remove the freewheel mechanism, it must be pulled, while the axle remains inside. The ratchet pawls and their springs will remain in place. Removing the Mirage and Veloce bushings, as well as the old style Chorus and Record bushings, may require you to first loosen the small socket head screw (about 2mm) located in the right locknut. On newer versions, it is no longer there, so remove the locknut on the right using a 17mm wrench, holding the axle with a 5mm socket wrench or a second 17mm wrench.

Little tricks.

After installing the springs and pawls, wrap the compression tool around the pawls (the hook should point outward). Gently slide the freewheel back onto the axle, partially inserting the pawls into the drive ring, but leaving enough room to pull out the compression tool, disengage and gently pull out. The freewheel hub should slide into place, turn it counterclockwise while re-installing to help the pawls get into place. If you do not have a tool for squeezing the pawls, a piece of sturdy thread is suitable for sewing. Wrap it around the pawl sleeve a couple of times to tighten it, then a couple more times. When the freewheel is partially in place, gently pull the thread out. Install the locknut.

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 a chain, a great will not even be able to get under way. Timely replacement of transmission system components is the most important component of any type of bike repair. from simple two-wheeled road bugs to road and mountain superbikes.

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.

Procedure

Step-by-step instructions for parsing:

  • The bike is installed with the wheels upwards and is in a stable position. The bike must stand on a flat surface and not carry out additional movements that can adversely affect the removal of parts;
  • We remove the wheel located at the back, this can be done using a wrench of the appropriate size. The chain for parsing the star is removed in order not to interfere;
  • Use a whip to fix the cassette in one place, untwist the cassette itself using a puller put on the nut;
  • After that, we remove the plastic ring, which serves as a kind of protection and establish a further front of work (directly install a new one or try to clean and lubricate the parts).
