Steps to Fix a Skipped Chain
ディーラーApril 26, 2024
For some people, fixing a bike that has skipped a chain can seem like a daunting task. It may even seem like a job that should be left to the professionals. But if your bike chain keeps slipping, there is a step-by-step way to identify the problem and repair it so that your bike chain will never skip again. Below are 6 easy steps to fix a skipping bike chain.
Step 1: While stationary, manually pedal your bike while shifting gears. You want the chain to be on the smallest ring at the ear and one of the largest rings at the front. This will make it easier to check and replace. From this position, try shifting again. If the chain doesn't shift, you probably need to increase the chain tension on your bike.
Step 2: Next, look at the back of your derailleur. There is a small piece of gear where the cable goes through the derailleur. That is the barrel adjuster. Turn it away from you.
Step 3: Now, go back to your shifters. With the bike stationary, try shifting again. You should be able to shift into the smallest ring on your cassette. If not, you still need to increase the tension. Go back to the barrel adjuster and turn it some more.
Step 4: If the first three steps don't fix your bike chain skipping or slipping problem, you should inspect your chain. Look for defects. Is the chain rusty? Old? Loose? Too tight? These are factors that may affect the repair. If the chain or flywheel is defective, it should be replaced.
Step 5: You probably need to tighten or loosen the cable. Look at your derailleur again and find the end of the cable. It's held in by a small bolt-like part. Adjust this bolt to tighten or loosen the cable. Then shift again to see if your chain skips.
Step 6: If all other methods fail to stop the skipping, find the limit screw. This is the screw that should be at the top of the derailleur. Sometimes it has the letter H on it. The reason why your chain won't move onto the smallest cog may be that this screw is over-tightened. Loosen the limit screw and try shifting again. You should now be able to shift properly and your bike chain should no longer slip.
