3x9S Bicycle Trigger Shifter

How to solve the problem of Bicycle Trigger Shifter when the chain skips teeth or gets stuck?

When the chain skips teeth or gets stuck, the Bicycle Trigger Shifter may need to be adjusted or repaired accordingly. Here are some suggested resolution steps:

Stop riding and inspect: First, stop riding immediately to avoid further damage to the chain and derailleur. Then, observe the specific location where the chain is stuck or skipped teeth to determine the problem.
Adjust the chain tension: If the chain is too loose or too tight, it may cause skipping or jamming problems. This can be solved by appropriately adjusting the chain tension. Specific methods include adjusting the limit screw on the thumb shift transmission, or appropriately shortening or increasing the chain length according to the actual situation.
Cleaning and Lubricating: If there is debris or dirt on the chain and gears, it may also cause binding or skipped teeth. At this point, you can use a clean cloth or brush to clean the chain and gears, and then apply an appropriate amount of bicycle-specific lubricant to reduce friction and jamming.
Check and replace worn parts: Components such as chains, sprockets, and derailleurs can also cause skipping or seizure if they are severely worn. Check these parts regularly for wear and replace them as necessary.
Check the shift cable and tailhook: If the shift cable is bent or broken, and if the tailhook is deformed, it can cause chain problems. Therefore, the condition of these components also needs to be checked and replaced if necessary.
Adjust the derailleur: Sometimes, chain skipping or sticking problems can also be solved by fine-tuning the position and angle of the derailleur. This is accomplished by adjusting the trimmer screw on the transmission.
If none of the above methods solve the problem, it is recommended to seek help from a professional bicycle repairman. They can perform a more in-depth inspection and repair of your bike and shifter, ensuring your ride is safe and smooth.

In addition, in order to avoid similar problems from happening again, it is recommended to perform regular bicycle maintenance and upkeep, including cleaning the chain, lubricating the gears, checking and replacing worn parts, etc. This ensures that the bicycle and shifter are in good condition, improving riding comfort and safety.
