How To Put A Cock On A Speed Bike

Removing the lock

According to the technology of changing the chain on a bicycle with detachable link speeds, special pliers are used. In fact, you can take in the area of ​​the lock with both hands (preferably with gloves) and pull the ends tenaciously to each other.

Important points

In addition to conventional devices, there are models with a lock. a special link, which is slightly different in shape from the others, and allows you to open the link with the help of reverse tension without using a squeeze or other tools, the main thing is to correctly put the Castle link. It is not recommended to open the links next to the lock, as this will reduce the reliability of the entire mechanism.

It is very important to remember how the chain is connected to the system, cassette and switches before starting the removal. without a little experience in installation and dismantling, it may be difficult to put it back on.

Here, for example, in setting the rear derailleur on a bicycle.

How to replace a chain on a bicycle with your own hands

The need to remove / install a bike arises for various reasons. Someone regularly boil it in paraffin or wax, someone decided to carry out a comprehensive cleaning in a can of gasoline, and someone came to such a state that the chain on a bicycle slips under load and needs to be changed. How to do this is intuitively clear, but for someone new to the operation, it is difficult to do without explanations and answers to exciting questions.

How to install a chain on a bike

Any vehicle needs maintenance. Bicycles are NOT excluded. Their key element in the transmission unit is the chain. High-speed bicycles are inherent in a great “finicky” for normal functioning. The frequency of chain replacement or maintenance is largely determined by the riding style. For example, riders do this while riding. When and how to change the chain on a speed bike?

Bicycle chains come in two types: lock and solid. Disconnecting the lock variation is NOT difficult. It is convenient to do this with a regular thread (wire), threading it into adjacent links (before and in front of the lock) and tightening the loop. The main thing is to avoid damaging the lock and DO NOT lose it.

Opening a continuous chain is possible only if there is a special squeeze, although the procedure itself also cannot be classified as complex tasks:

  • You will need to install the chain in the position of pressing-pressing the wasp.
  • Tightening the pin pull-out screw.

Axial pressing is inherent in the opposite sequence: connecting the links and pressing the pin by means of a screw.

What tools are important to have to replace the chain:

  • The key with which the rear wheel is removed.
  • Pliers to hold segments and pins.
  • Squeeze. As noted above, this device is used to press out and press in the pins.

Cyclists, and those who do not have sufficient experience in such matters, are advised to memorize the general scheme, reflecting the location of the chain on the system, cassette, switches. Then the procedure for its subsequent adjustment will not cause difficulties.

As soon as all the nuances are fixed in memory (or on paper), you can proceed to further steps:

  • Cleaning links from dirt accumulations. If this is not done, dirt will be a significant obstacle to the next steps.
  • Removing the rear wheel. The absence of this detail simplifies all actions, although experienced craftsmen safely skip this stage. In fact, it does not apply to mandatory measures.
  • Extrusion of the pin present in all links (the metal cylinder that closes the link). This is where the pomace applies.
  • Separation of one link.
  • Withdrawing extreme links from the switch system.

At this point, the removal of the chain (worn out or requiring cleaning) can be considered complete. The procedure itself is quite easy if you have a tool and basic knowledge. Accuracy of execution and the absence of forceful actions during the pressing process are very important.

With bicycles that have one gear (singlespeeds), everything is limited to a chain canopy on a star-shaped part and a latching snap-in or pressing in a pin. The design of high-speed bikes suggests some difficulties in this issue.

They can be designated by the following points:

  • Locking derailleurs on small transmission stars.
  • Next, a chain is put on the teeth of the stars. In this case, it is important to take into account the location of the rollers involved in its tension.
  • Then the chain links are aligned.
  • The chain is clamped and pressed in or the lock closes.

At the final stage, the move is checked. For this purpose, the pedals are rotated. Incorrect installation is characterized by sagging of the installed element and difficult twisting. If this is not observed, the installation of the chain is done according to all the rules.

In what cases, besides wear, the chain is removed:

  • For deep cleaning when it is necessary to remove lubricant and accumulated abrasive.
  • To replace damaged links.

A failed chain stretches, its links shift, harming the sprocket, which negatively affects the switch. It is difficult to visually determine the degree of wear.

Therefore, they use a simple measurement, that is, you need to
measure twenty-four links, or rather their total length:

  • With a size of 30.5 cm, we can talk about the normal state of the chain.
  • An indicator of 30.65-30.75 cm indicates the need for replacement.

By the way, cutting the stretched chain does NOT solve the problem. Stretching is inherent in uniform distribution. In this case, damage to the stars cannot be avoided. As you know, “star” parts cannot be repaired. It is cheaper to change the chain than to replace more expensive components.

The plot will tell you how to replace the chain on a bicycle

Now how to put the chain on a single-speed bike in place.

The idea is this: First, it is completely put on one of the stars (usually on the back, but you can also on the front) and thrown over the second sprocket (front or, respectively, back) so that they lie on the part of the teeth. Further, when scrolling the pedals in the direction of travel, the chain is captured by the remaining teeth of the sprocket and completely lies on the entire sprocket and is thus put on.

How to remove a bicycle chain without a lock

First, place the chain closer to you so that it is convenient to remove it after opening and brings a new analogue to the stars. To do this, simply move the rear derailleur to the end position (smallest sprocket), and align the front derailleur with the third gear gear (largest sprocket).

Squeezing a pin out of a link is much easier than pushing it back in. Select one of the constituent elements tenaciously and issue here in any of the ways:

  • Tap with a hammer through knitting needles or a thin stud.
  • Squeezing with a hard tip, fixed on the chain release bolts.

Important! When tapping or pressing out, the back plate of the link must rest against something. For example, a special rib is provided for this in the squeezing device. Wielding knitting needles and a hammer, the bicycle chain can be placed on a metal substrate (for example, a rail, a weight) or a hard stone, but so that Pin has a place to go.

It is more convenient to squeeze out at the lower level. After disconnecting, it is easier to withdraw tenaciously at idle, when the pedals are spinning in the opposite direction.

Note. DO NOT press out the pin completely. It is very difficult to insert it into the outer plate. If you do not feel the position, proceed in steps: rotate the handle of the squeeze bolt, remove it, assess whether it is already possible to open the link. If yes, then Squeezing out is considered to be over, and in the case of “available”. put the squeezing device back on and repeat the cycle of actions.

How to install a new bike chain

Let’s assume that all the technology requirements are how to choose a chain for a high-speed bike. Completed successfully. THOSE. Before you is a part that fits the width of the rear and front sprockets and you just have to put it on:

  • Position the product so that the extruded pin is closer to you.
  • Run the chain over the large chainring in the idle direction (reverse drive pedaling) through the front derailleur.
  • Put the chain on the cassette and go around the rollers of the switches according to the diagram shown in the figure.
  • Press the pin with a squeeze.

Note. You can only squeeze a link with a squeeze. When pressing in, ask an assistant or Fix the rear derailleur with a piece of wire so that the chain hangs on the lower tier. So the risk of damaging the opposite plate can be virtually eliminated.
