1. Pass the chain through the front derailleur and hang it on the smallest chainring. As shown in the picture below:
2. Hang the chain on the smallest wheel. As shown in the picture below:
3. Hang the chain on the pulled-out front guide wheel. As shown in the picture below:
4. Hang the chain on the rear guide wheel that is pulled out. As shown in the picture below:
5. Tighten the chain, but don’t pull it back too much (the smaller the better), and don’t let it fall. As shown in the figure below:
6. On the premise of not falling, count four nodes backward from the node aligned with or close to the chain street. The fourth node is the place that needs to be cut off. Clamp the chain on the connector and cut the chain using the connector. As shown in the picture below:
7. Connect the two ends of the chain together. As shown in the figure below:
8. Use a chain cutter to press the chain nodes into the chain. As shown in the figure below:
9. Press the node into the chain, so that the outside of the node is parallel to the outside of the chain, and there should be no protruding parts. As shown in the figure below:
Extended information
If the user's bicycle often fails to shift, the shifting is not smooth, the chain slips, etc., the chain is basically broken. For example, you can still get by in the commonly used flywheel positions, but once you shift to a gear that is not commonly used, there will be noise, or the shift will not be in place, or the chain will not bottom out on the chainring. However, in such a situation, it is difficult to accurately determine whether the chain will cause simultaneous damage to the flywheel chainring.
If the user has a spare chain on hand, the user can compare the old chain with the new chain. Measure the distance between every 10 connecting rod pins and compare it with the measurement data of the new chain. If the length exceeds 1mm, the user needs to replace it. Generally, the length of the chain is about 108 sections, so if the 10 sections are 1mm longer, then the entire length has exceeded 1cm.
