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.
How to remove the chain from a bicycle
Depending on the riding style, the question of removing the chain arises either almost immediately after the start of riding, for example, in a trial or downhill, or, after many kilometers of walking, when maintenance and replacement of the chain is required.
In the absence of squeeze, you can install everything back without it. Pliers and any strong cylinder, for example, a small hexagon, will help. Gently clamp 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 by 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.
Standard withdrawal process
All guides describe the same removal procedure. This will require, first of all, a small set of tools. without them it will be quite difficult.
Chain Removal Situations
Maintaining your bike is very important, and there may be several reasons for removing the chain:
- Deep cleaning. it is recommended to remove all elements from time to time and clean from grease and accumulated abrasive.
- Link damage and replacement.
- Replacing a worn chain.
- Change in length with a new combination While, for example, on a mountain bike.
Home wear is primarily determined by stretching. An overstretched chain is cause for concern, as link misalignment will severely damage the sprockets and can be hazardous to derailleurs.
It is quite difficult to notice wear by eye, and to determine it there is an indicator. the length of 24 links:
- If it is 305 mm (304.8 value for a new set), everything is in order;
- 306.5-307.5 mm. it’s time to change;
- 307.5 mm. if the bike was still in use with such wear, then most likely the entire set of sprockets is damaged;
- 308 mm. the value of the damaged transmission.
Objectively, it is recommended to service the transmission every 500 kilometers, but this value is NOT Fixed, since 50 kilometers on rough terrain with an abundance of sand and mud in wear can correspond to another thousand on clean city roads.
Some people prefer to cut the chain, but the stretching is usually evenly distributed, and the links can still damage the stars, which can no longer be repaired.
Let’s take a step by step how to remove the chain from the bike:
- We clean the links from dirt. it will interfere with each subsequent step.
- Removing the rear wheel is NOT required, but it’s much easier to work without it.
- Extrude the pin (the metal cylinder that closes each link) using a squeeze.
- Disconnect equals link.
- Remove extreme links from switches.
The reverse sequence is the same. put the chain in place and assemble the structure back, rivet the pin with a squeeze, and rotate it in the opposite direction.
- Key for removing the rear wheel;
- Pliers for holding segments and pin;
- Forcing. a device for pressing out pins, without a lock. the most important tool in the process.
Removing the chain from a bike is very easy if you have a simple tool or basic knowledge of the process. The most important thing is to act carefully, as forceful action with extrusion can be dangerous.
Upset rear derailleur
Why does a chain on a bicycle skip at all under load? It either jumps over the stars due to insufficient frictional force, or it got between the sprockets, where there is no hook at all.
Frictional imbalance can result from a reduction in the number of contact pairs “cassette tooth-chain link”. This is influenced by the position of the chain tension adjusting screw located on the rear derailleur. By turning this bolt, you can move the frame up or down.
How to control stretch.
What to do to prevent the chain on a high-speed bike from slipping when the pedals are loaded
If you have NOT touched the tension screw tenaciously on the rear derailleur, and the mechanism itself is working properly and accurately, there is a reason to go into its settings. An Intervention Has Occurred. Learn How Shimano Shifting Adjustments Are Made On A Mountain Bike.
The most accurate measurement tool. Adjust the inner dimension to 119 mm and measure the distance between the chain links. Based on the actual size, you can judge what to do with it:
- 119.7-120.6 mm. You can continue driving.
- 120.6-120.9 mm. Need to change.
- More than 120.9 mm. Replace with cassette.
Again, for Campagnolo, these control intervals are NOT relevant and rarely monitored. Let’s say that it is customary to kill the same Record at the beginning of the overshoot (5,000-7,000 km), which means there is no need for control.
Lubricate the bike chain
NOT anything! The question should NOT be covered in two sentences, but it is useful to delve deeper into the topic. Therefore, take an interest in the best way to lubricate the bicycle chain at home.
The chain is lubricated regularly. The specific interval determines the type of lubricant used or the mileage, after which a rustle appears.
A new chain slips
It would be nice to replace the cassette. If the previous chain did not dance over the stars, then you can leave everything as it is. the “novye” will roll in and the smoothness of the course will be restored. Depending on the degree of “stretching” of the teeth, running-in will take from 50 to 150 km.
Why chain slips on a speed bike 2 reasons and recipe for treatment
Statements such as “I’ve been rolling for the third year, we do NOT service anything, and everything is fine” ultimately lead to serious problems. Slipping tenaciously with power pedaling is one of them. This fact happens more often from ignorance: what and when needs to be changed. Less often, interruptions in the smoothness of the chain are caused by actions that contradict the instructions for setting up SEPARATE components.
Why Mountain Bike Chain Can Slip Under Load
There are, in fact, only two reasons. The rear derailleur is incorrectly adjusted or the chain and sprockets of the system and / or cassettes are worn out.
What exactly to do
If the old chain has already started to slip, feel free to buy a new cassette and chain. Inspect the system stars before installing new components. Their profile should NOT be unduly deformed.
And remember the classic rules:
- One cassette is enough for three timely replacement tenacious.
- The favorite star of the system walks about 10,000-15,000 km.
