Bike Won’t Shift? Here’s How To Fix It

Having trouble shifting gears on your bike? Don’t worry, we’ve got you covered.

If your bike won’t shift, there are a few common issues that could be causing the problem.

Let us guide you through troubleshooting gear shifting, adjusting the derailleur, and checking the shift cables.

With our step-by-step instructions, you’ll be back to smooth shifting in no time.

And if all else fails, we’ll also discuss when it’s best to seek professional help.

Common Shifting Issues

Bike Won't Shift? Here's How To Fix It

If your bike won’t shift, there are a few common issues you might be experiencing.

Shifting problems can be frustrating, but fortunately, there are simple solutions to fix them.

One possible issue could be that the gears are not properly adjusted.

Over time, the cable tension may become loose or misaligned, causing difficulty in shifting smoothly.

To fix this problem, you can adjust the barrel adjuster on the derailleur or use the limit screws to align the gears correctly.

Another common issue is a worn-out chain or cassette.

If your chain has stretched or your cassette teeth are worn down, it can affect how well your bike shifts gears.

In this case, replacing either one or both of these components will solve the problem and improve shifting performance.

Lastly, dirty and dry cables can also cause shifting problems.

Dirt and grime build-up can create resistance and hinder smooth gear changes.

To fix this issue, simply clean and lubricate your cables regularly.

Troubleshooting Gear Shifting

When troubleshooting gear shifting, it’s important to check the condition of the derailleur.

The derailleur is responsible for moving the chain between gears smoothly and efficiently.

If it’s damaged or misaligned, it can cause issues with your bike’s ability to shift properly.

To troubleshoot gear slipping, start by inspecting the derailleur for any signs of damage or wear.

Look for bent or broken parts, loose bolts, or excessive dirt and grime. Clean and lubricate the derailleur if necessary.

Understanding gear ratios is also crucial in troubleshooting gear shifting problems.

Gear ratios determine how easily you can pedal at different speeds and inclines.

If your gears are not shifting correctly, it could be due to a mismatched combination of front and rear gears that creates an improper ratio.

Familiarize yourself with how your bike’s gears work together and make sure they are properly aligned.

Adjusting the Derailleur

To adjust your derailleur, start by making small tweaks to the barrel adjuster until you achieve smooth and precise gear shifts.

Derailleur maintenance is crucial for ensuring optimal performance and preventing any issues with shifting gears on your bike.

Over time, the derailleur may become misaligned or lose its proper adjustment due to wear and tear.

To begin the process of adjusting your derailleur, locate the barrel adjuster.

This is usually found where the derailleur cable enters the rear derailleur.

Use a 5mm Allen wrench or your fingers to turn the barrel adjuster clockwise or counterclockwise in small increments.

Start by turning it one-quarter of a turn at a time and then test out how smoothly your gears shift.

If you find that shifting is still not as smooth as desired, make additional adjustments in small increments until you achieve the desired result.

Remember to shift through all of your gears while making adjustments to ensure that each gear change is smooth and precise.

Regularly checking and adjusting your derailleur will help maintain efficient gear shifting on your bike, ensuring a smoother ride overall.

Don’t forget to perform routine maintenance on other components such as chain lubrication and cable tension for optimal performance.

Checking the Shift Cables

Check the shift cables on your bicycle regularly to ensure they are in good condition and properly adjusted.

Neglecting this important maintenance task can lead to frustrating rides and poor shifting performance.

To keep your bike running smoothly, follow these tips:

  • Lubricate cables: Over time, shift cables can become dry and sticky. This can cause resistance and make it difficult for the derailleur to move smoothly between gears. Regularly lubricating the cables with a high-quality bike lubricant will help reduce friction and improve shifting.
  • Inspect for wear: Take a close look at your shift cables for any signs of fraying or kinks. If you notice any damage, it’s crucial to replace them as soon as possible. Damaged cables not only affect shifting but can also lead to sudden cable failure while riding.
  • Consider replacing shifters: If you’ve tried adjusting your shift cables but still experience issues with shifting, it may be time to replace your shifters altogether. Worn-out or damaged shifters can hinder smooth gear changes even if the rest of your drivetrain is in good condition.

Seeking Professional Help

If you’re experiencing persistent issues with your shifting, it might be worth seeking professional help.

While there are many benefits of DIY bike maintenance, sometimes the problem is beyond your expertise.

It’s important to recognize the signs that indicate a serious shifting problem.

One sign is if your bike won’t shift at all, no matter how much you adjust the gears or cable tension.

This could be due to a bent derailleur hanger or worn out shift cables that need replacement.

Another sign is if your bike skips gears or shifts unexpectedly while riding.

This could be caused by a worn cassette or chain, which may require professional tools and knowledge to fix properly.

Seeking professional help can save you time and frustration in the long run.

A certified bike mechanic will have the experience and specialized tools necessary to diagnose and fix complex shifting problems accurately.

They can also provide valuable advice on proper maintenance techniques and preventive measures to avoid future issues.


By following these troubleshooting steps and seeking professional help if needed, you can get your gears back in working order in no time.

Remember to check for common shifting issues, adjust the derailleur if necessary, and inspect the shift cables for any damage.

With a little patience and know-how, you’ll be back on the road enjoying smooth gear changes in no time.
