How to replace a chain on a speed bike

Opening the lock and squeezing the link axis

It is quite simple to open the lock: use a screwdriver or other object (for example, a knitting needle) to pry on the pincer clamp. The main thing here is not to damage it, or even better. not to lose it, otherwise it will not be possible to fix the chain later. Next, we decouple the entire link. That’s it, you can remove the chain and do whatever you want with it: clean it, throw it away or shorten it. However, we’ll talk about this a little later.

Disassembled lock

It is possible to separate a continuous chain only with a special tool. a squeeze. With its help, it will be possible to easily disassemble the link without damage. The procedure is simple, but you shouldn’t rush:

  • First, select the link for disassembly.
  • We insert the chain into the position of pressing out and pressing in the pin (link axis).
  • Use the handle to tighten the screw and take out the axle. Extrusion direction. towards the squeeze screw, that is, towards yourself.

You should not completely extract the pin, since it will not be easy to return it to its place later.

The squeeze loosens the axle a little, therefore, when re-disengaging, another link should be selected. Pressing the axle into the link is carried out in the opposite order: connect the adjacent links together and press the pin in with a screw.

How to change the chain on a multi-speed bike at home

The need to remove / install a bicycle chain arises for various reasons. Someone regularly boils 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 bicycle chain slips under load and needs to be changed. How to do this is intuitively clear, but for whom the operation is new, it is difficult to do without explanations and answers to exciting questions.

Elimination of defects

A common form of wear is chain slack when chain length increases from original length. Previously, the critical values ​​of the length of the bicycle chain were considered, at which it cannot be used. Everything is correct, but the chain does not have to be thrown away immediately, but it can be repaired. Under prolonged loads, the axles loosen, which causes longitudinal and lateral expansion. It is impossible to eliminate the transverse, but it is quite possible to tinker with the longitudinal.

It is necessary to remove unnecessary links in such a way that the chain calmly, without interference, passes over the large star. With the help of a squeeze, excess links are removed, the axial shafts are completely pulled out of the removed elements. The main thing here is not to make a mistake and not pull out too many links.

If you have to ride with a stretched chain, then in order to avoid its falling off, you can install the so-called chain dampers. parts that prevent the chain from flying off when driving. There are several types of such devices:

  • Roller with two locks.
  • Wide rollers.
  • Frame (or rollerless).

This is what bike pacifiers look like.

Using pacifiers as protection is fine, but it would be better to consider changing the circuit.

In the absence of squeeze, you can install everything back without it. Pliers and any sturdy cylinder, for example, a small hexagon, will help. Gently clamping the cylinder, the pin can be riveted similarly to the work of the squeeze, it just requires much more attention and application of forces.

Models with a lock can be disengaged using a tight rope or cable. This allows for prompt repairs literally in the field, for example, when the chain suddenly breaks on a short hike.

At the crossroads of two technologies: methods of replacing a worn chain on a bicycle at speeds

The main purpose of the procedure is to disengage the old chain and connect the new one together. Before doing anything, check how the chain is engaged now. It either represents a single whole, or has a detachable link (lock) in its design. This is important, since the type of fastening determines the list of required tools and, in fact, the maintenance method.

Removing the lock

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

The technology is similar to the technique of changing a bicycle chain without a lock: remove the old one, shorten the new one and put it on. And we can say that here you cannot do without squeezing. extra links need to be removed with something.

Although here you can omit the recommendation about the incomplete pressing out of the pin. in the case of using the lock, it just needs to be completely removed. And then the alternative works 100%: the hammer and the spoke do their job, but you don’t need to press in anything.

Attention! When removing unnecessary links, see how the lock is installed: both ends must end with inner plates

Decoupling techniques

  • If there is a lock in the chain, it is enough to open it.
  • If the chain is a single unit, it is necessary to press out one of the axles (pins).
