It is more lightweight and economical compared to electric vehicles, while also serving as a form of physical exercise. However, there are occasional issues with bicycle use that can prevent riding, such as a stretched chain or deformation due to external forces. In such cases, it is necessary to replace the chain. So, how should you remove and replace the mountain bike chain?

Cut the Chain

1. First, set the chain on the inner sprocket behind the upper sprocket. This is when the chain tension is loose, making it easier to perform tasks. During the operation, be mindful of the black pin, which marks the spot for inserting the connecting pin; do not cut the chain here.

2. Attach the cutter to the chain, press the pin against the axle, and then turn the handle to push the pin out with the axle; once the pin is removed from the chain, remove the cut chain segment.

Two: Connect the Chain

1. We have replaced the mountain bike chain with a new one. Fit the chain over the front outer sprocket and the rear bottom sprocket to determine the chain length; the chain does not need to pass through the derailleur. Retain 2 links at each end of the chain, then cut off the excess links with a cutoff tool. Reminder: Carry a few extra links with you while riding for emergencies.

Step the new chain through each component, ensuring that you do not misplace the chain through the sprocket carrier after passing the derailer.

3.叠放链条，插入连接销，接着用断链器将连接销压入链条中，多余的部分可用断链器或剪钳剪除.

4. After the connection, manually move the chain to ensure smooth operation and prevent stiffness. With this, the chain replacement is fully completed. Remember to regularly maintain and lubricate the chain.
