Cracked Head Tube? Everything You Need to Know

If you’ve ever heard the crack of your bike frame from getting hit by something, you know how frightening it can be to ride away from the incident without noticing the damage that was done. 

Fortunately, if you have a cracked head tube, you can breathe easy knowing that while it may need to be replaced or repaired, it’s not time to start shopping for another bike yet. 

You just need to know what to do and where to go so that you can get back on the road as soon as possible! This post will help you with all of that.

Is it Safe to Ride With a Cracked Head Tube?

While a cracked head tube may not seem like a big deal, it can be quite dangerous

If the crack is severe enough, it can cause the frame to collapse, which could lead to serious injury or even death.

That being said, if you have a cracked head tube, it’s important to get it fixed as soon as possible.

Why Is There a Crack in Your Bike Head Tube?

There are a few reasons why your bike head tube might be cracked. Here are some possible causes:

  • First, if you’ve had a crash, even a minor one, the impact can cause the head tube to crack. 
  • If you ride regularly on rough roads or trails, that vibration can eventually lead to a crack. 
  • Metal fatigue can occur over time, causing the head tube to weaken and eventually crack. 
  • If you live in an area with extreme temperature changes (hot summers and cold winters), that can also contribute to cracking. 
  • If your bike frame is made of steel or aluminum, those materials are more susceptible to cracking than titanium or carbon fiber. 
  • Finally, if you’ve recently had your bike serviced and the mechanic over-tightened the headset, that could also cause a crack.

Can You Repair a Cracked Head Tube?

While it is possible to repair a cracked head tube, it is generally not recommended

Cracks in head tubes can weaken the frame and cause other problems down the road. If you do decide to repair a cracked head tube, be sure to have it done by a professional.

How to Repair a Cracked Head Tube?

If you have a cracked head tube, the first thing you need to do is determine the severity of the damage

If the crack is only superficial, you may be able to repair it with a patch kit. However, if the crack is more severe, you’ll need to replace the head tube.  

The process is fairly straightforward, but it’s important to take your time and make sure everything is done correctly. 

  1. First, remove the old head tube
  1. Then clean up any remaining residue before installing the new one. 

Make sure all parts are in good condition before you put them back together – check for any cracks or dents that might interfere with how well they fit together. 

  1. Once you’ve got everything lined up, tighten the bolts to secure it in place. 

When tightening, start from the bottom (closest to the bike) and work your way up. 

If you’re going through an entire frame instead of just replacing a head tube, then there will also be seat stays which require removal and installation as well. 

  1. Be sure to inspect these carefully when removing them as it can be easy to miss small cracks. 
  1. After everything has been tightened down, inspect the bike thoroughly for any loose parts or anything else that doesn’t seem right. 
  1. Lastly, use some light grease on bolts so they don’t get stuck later on!


If you have a cracked head tube, don’t worry. With a little bit of know-how and the right tools, you can fix it yourself.

I hope this guide has given you all the information you need to get started. So get out there and get it fixed!
