How to put a lock on a bicycle chain correctly

Four ways to lock your bike on the street

Here are four popular methods for blocking your bike outside. Which one suits you best will be clear given the high cost of your bike and your lock.

Fastening your bike on the street

Although more than 50% of stolen bicycles are stolen from home, your bike is at very high risk of being outside. A badly fastened bike will disappear very quickly. It is worth carefully considering where you will attach your bike. Even if for a suitable place you have to walk a decent distance along the street and be able to properly attach the bike, then it is better to do just that.

When planning to leave your bike on the street, you should always evaluate the environment and understand how likely it is to steal a bike in a particular area. However, there are some generally accepted ways that we can follow.

Always try to choose a location with a lot of people walking by, and ideally a location with an overview of CCTV systems. If you see that the area is not safe, avoid it. Or, if you cannot avoid dangerous terrain, use an additional lock.

Choose a place where many other bikes are already parked and you will immediately understand how to hook the bike to the frame in the parking lot. The best way to do this is in the middle of the parking lot, not around the edges. This method is advantageous for three reasons. First, there will necessarily be a bike that is worse fastened, and therefore more tempting for a thief than your well-locked bike. Secondly, having many bicycles in one place will give the thief less room to maneuver and hinder the efficient use of his tools. And thirdly, in most cases, ordinary passers-by will not pay attention to the actions of the thief during the theft, and are more likely to pass by. In places where many bicycles are strapped at once, the concentration of caring cyclists is very high. Therefore, this will give the hijacker additional doubts.

The bike will be safe only if the object to which it is fastened is also secure. So make sure you can choose a fixed, stationary object that is difficult to break. Make sure the bike cannot be lifted over the top of the object to which you strapped it. Or that this object cannot be easily unscrewed or disassembled. Avoid trees, aluminum structures, or wooden posts. If you are opting for metal railings, try using as many beams as possible to secure the lock. The best option for such an object is specially designed bicycle parking, firmly bolted to the ground.

With one lock and cable

Another very popular method is to use one good lock and cable. Attach a U-lock or chain around the rear wheel, frame and bike rack as described above. Then pass one end of the cable through the front wheel, passing through the first loop, the second loop, and secure with the main lock. The problem with this method is that the cable is the only protection for the front wheel. Since all cables can be cut, they offer almost zero protection. However, many people think that visual and psychological factors are constraining and a cable will suffice.

With one lock and chain

A good option is to combine a lock-chain and U-lock. If you lock your bike in the same place every day, there is a good advice: you can leave a heavy and massive chain strapped on in the parking spot, and carry a not very heavy U-lock with you. The disadvantage of this method is that your castle is always available for a thief, and he has the opportunity to train hacking. So be careful! Try to attach the chain so that it does not touch the ground.

Two locks

The safest way to lock your bike with two padlocks to a parking lot firmly in the ground. The first lock should go around the rear wheel, frame and parking. The second one should go around the front wheel, frame and parking lot in order to secure all parts of the bike. It is best to use two different types of locks, this will force the thief to use 2 different sets of tools for each lock.

How to properly fasten a bike with a lock?

Hopefully you’ve already read about the different types of bike locks. And maybe you have an idea which lock will suit you best. But it’s not always about the castle. You should also know how to fasten your bike correctly and how to properly attach a lock to your bike! No matter how you use your lock, if you don’t use it correctly, your bike will be stolen.

over, it is worth thinking about how you are going to store and how to properly park the bike. This can help you choose the right lock. There are different ways to secure your bike and there are many different ways to lock your bike.

You also need to mention where you fix your bike, because that is very important too. There are 3 main places: on the street, at home, and possibly at work.

lock, bicycle, chain, correctly

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).

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

How to put on the chain lock correctly. How to dress correctly.

The chain is the key element of the bike’s transmission assembly. Sequentially passing through the teeth of the drive sprockets, it transmits torque to the rear wheel, thanks to which the bike rides. In the process of movement, the chain mechanism is subjected to dynamic loads, which over time leads to its wear.

On singlespeeds, as a rule, the chain is designed for the entire life of its operation: when moving along the stars, it walks smoothly and straight, without deviations. Chains are more complicated on multi-speed bicycles: there is no right angle between the front and rear sprockets, which is why it is always at an angle relative to the frame. The stresses on the chain mechanism increase several times compared to parallel transmission, which leads to periodic wear. To avoid damage to the entire transmission unit caused by wear of the chain, it must be replaced in time.

Not only do the “speed” chains need to be removed, they are often removed from single-speed bikes for periodic repairs or cleaning. How to remove the chain from the bike and put it back, we will tell you in this article.

Fitting the chain to the bike

To put the chain on the singlespeed, it is enough to hang it on both stars, press in the pin or click the lock. With high-speed bikes it will be a little more difficult:

  • Fix switches to small stars.
  • With regard to the location of the tensioning rollers, put the chain on the stars.
  • Combine links.
  • Clamp the chain and press in the axle. If the bike chain is with a lock, we do without squeezing.

After the installation is completed, it is necessary to check the course of the chain: rotate the pedals several times. If there is no sagging or obstruction during twisting, then the chain is of the optimal length and is installed correctly.

Every owner of a two-wheeled horse will be able to cope with the removal and installation of a bicycle chain. An uncomplicated and simple procedure will not take much time, but it will perfectly help on further trips!

How To Lock Your Bike. Secure Your Bicycle From Thieves

Lock and solid chain

The locking chain is equipped with a special clamping device. It is not difficult to unhook and put on it. you just need to disconnect the lock. To find it, we carefully examine the chain on both sides and find a detachable link. In principle, it will not be difficult to find it on a clean chain: a tick is put on top, which fixes the link and does not allow it to move apart. Also, the manufacturer’s inscription is usually embossed on the key link. If you cannot find the lock for a long time, then either the chain is dirty, or it is lockless, or solid.

A bicycle chain without a lock simply cannot be disconnected: all the links on it look the same, however, and are hooked together too. This is a big inconvenience when cleaning, for example, it is necessary to carry out a “general cleaning” in a solvent. In the case of the keylock, everything is simple. I stole it and put it in kerosene. Solid bike chain, even taken off the stars, will remain hanging on the frame.

In terms of removal, a chain with a lock is, of course, more convenient than its counterpart. However, for some reason, the fastening may loosen: the tick fly off, and the link itself can be disengaged. There are no such weak points on bicycle chains without locks, and if it is torn, then the point is solely in its quality.

How to determine the degree of chain wear?

After making sure of the need to periodically change the circuit, you should proceed to explaining the process itself. First of all, you should learn how to determine the moment when the chain requires replacement, because it is difficult to systematically monitor the mileage. The most accurate way to determine the degree of wear is to measure the distance from the center of an arbitrary pin (the axis connecting the links) to the center of the twenty-fourth pin after it with a simple ruler. This distance should be 304.8-306.4 mm. If the measured distance is longer than the recommended one. chain needs replacement.

Disadvantages of using

Like any other bike part, the lock has its drawbacks. And the most important, perhaps, is strength. Since it can be disassembled in two, it automatically becomes less reliable than conventional chain links. This raises the risk that the chain is likely to break exactly where it is installed. But do not worry about this, because this happens extremely rarely and after long-term use.

Of course, a chain lock is a very handy thing. With it, you can easily disassemble and assemble the chain so that you can easily remove it from the bike and then install it. If you install a new copy, then it will last much longer and will not be life-threatening. That is, having installed a new one, you can not be afraid that it will burst at the most inopportune moment. Also, do not forget about the sizes that are suitable for this or that option. In some cases, the same spare part may be suitable for different sizes.


Malfunction symptoms

First of all, attention should be paid to chain malfunctions on multi-speed bikes. Traditionally, the travel time is determined by the mileage, but these values ​​are too approximate, because everything depends on the conditions of cycling: road quality, gear selection, speed, load on the pedals and, accordingly, on the chainring.

The first signs of a bike chain failure are inaccurate gear shifting and suspicious sounds (provided the chain has not lost its lubrication). The following method will probably help to determine the malfunction: bend it away from the largest sprocket and see the number of free teeth. If the chain comes loose from three or more teeth, then replacement is required urgently. Two prongs “warn” that wear is just around the corner, but you can still ride.

Using the same method, you can see the weakening of the chain on a single-speed bike: bend it away from the chainring and look at the number of teeth.

Another way to measure wear is to measure the length:

  • 304.8mm. Optimum Chain Length.
  • 306.5. 307.5. average wear, suitability for repair. You can ride while you can.
  • 308 mm. high degree of wear on both the chain and the sprockets.
  • than 308 mm. damage to the entire transmission.

Measuring elongation requires removing the chain completely from the bike.

With symmetrical details

A part of a symmetrical type has a simple shape and structure. For its implementation, two parts of the perfect identical appearance are taken. The main components are cheeks and pins.

The pins are made with an annular groove, which is connected to the hole of the second part. When tensioning the chain, this design shows excellent reliability results.

In order to open it, it is necessary to move the pins towards each other. When they match, the bike chain will open.

Types of bicycle chain locks, how to remove and install locks

Before installing a new lock, you need to make sure that there is no one on the bike that came with the purchase.

It is not difficult to locate the locking element, it usually has the manufacturer’s marking. Each driver decides for himself whether it is necessary to install this structure. Experts recommend hanging a lock if the bike owner plans to frequently work with the links, remove them, connect and disconnect.

How to properly lock your bicycle

Installation involves a process in which you must first remove some of the links so that there is room for the lock:

  • Removing links is best done with a squeeze tool, this tool allows you to carry out the process neatly without damaging the chain.
  • The removed links can be thrown away, as the locking element will go in their place.
  • After completing all the points, the structure should be fixed. To do this, stretch the chain until a click is heard.
  • If it is necessary to remove the installed structure, bend the chain and slide the hole until it opens.

It should be remembered that often working with bicycle parts requires additional strength and tools, so you should not rely on your hands. For long-term operation and safe use, no need to put the lock from the old chain.

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.

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 will loosen the axle a little, so a different link should be selected when re-disengaging. Pressing the axle into the link is carried out in the opposite order: connect the adjacent links together and press in the pin with the screw.

Types of locks for a bicycle chain, methods of installation and removal

Over the course of my life, I have come across 3 types of bicycle locks. Today I will tell you how easy it is to put and remove a chain lock in any form.

Bicycle chain with a lock. features, design

When choosing a lock, first of all, pay attention to the number of speed modes. Experts allow you to choose the same lock for the number of speeds from 6 to 8, which greatly simplifies the task.

Owners of multiple bicycles with the same number of speeds do not need to buy multiple locks. This factor also applies to chain manufacturers. As long as the speed numbers are the same, it doesn’t matter if the model is different, as the lock will still work. This is due to the fact that, despite the brand of the bike, the chains are usually set similar.

The peculiarity of the structure of the structure lies in the presence of easily detachable links, which consist of several plates. Due to the simple structure of the castle, it will not be difficult to open the links.

When buying such an element, you should pay attention to the box, on which the manufacturer often indicates all the necessary information that will be useful during operation. It is important to choose the lock in accordance with the number of speed modes of the bike.

Installation of the lock

Pass the plates with the axles into the rollers, align all the grooves and spread the chain in the area of ​​the lock in opposite directions, grasping it with both hands. Again, you can use pliers with a suitable profile, if available. In order for the lock to finally click into place in the absence of pliers at hand, follow the list of steps:

  • Rotate the pedals so that the lock is on the upper tier.
  • Hold the back wheel.
  • Step on the pedal with your foot. The section will stretch and the link will sit as expected.

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.

Model with a lock

How to check if the chain has a lock? As easy as pie! A quick inspection to see if the chain has a link that is different from its neighbors. This is the castle. You can disconnect it by sliding the pins on each of the links with your hands or pliers. To assemble the chain, you need to do the same in reverse order.

The sequence of actions for removing the chain from the bicycle without squeezing with your own hands

Pomace is a useful tool. However, it is not always at hand. What then is to be done? The prospect of staying with a non-working bike in the middle of pristine nature, somewhere many kilometers from the city, does not look attractive. You can remove the chain from the bike without squeezing. It will not be easy to do it yourself, but it is quite possible. Let’s consider in detail the options for parsing the chain with and without a lock.


Their design is extremely simple. there is a cheek on which 2 pins are located. They are pushed into the holes in the chain links and pressed in with a double-hole washer. Everything is fixed with a locking cheek.

With symmetrical details

A part of a symmetrical type has a simple shape and structure. For its implementation, two parts of a perfect identical appearance are taken. The main components are cheeks and pins.

The pins are made with an annular groove, which is connected to the hole of the second part. When tensioning the chain, this design shows excellent reliability results.

In order to open it, it is necessary to move the pins towards each other. When they match, the bike chain will open.

How to remove a spring-loaded cheek lock

This is the most difficult stage, it is not always possible to do it with bare hands. We need a screwdriver to remove the lock. As in the case of installation, you need to bend the chain so that the pin goes to the place on the bar where it can come out, but this does not happen without a screwdriver. You need to help the pin to free itself from the bar, so you need to hold a screwdriver in one of the hands and bend the chain, pressing on the pin with a screwdriver at the moment it approaches the expansion in the bar. As soon as the pin is released, you will hear a click. this means that everything worked out for you correctly.

These locks are not intended to be reused, they usually bend after being removed. But you can always try to bend it back and put the lock again if there is no other lock at hand.
