When to inspect your carbon bike frame?

The question we can start this article with is how often we should inspect our carbon frame? Here are a few occasions to help you understand the timing of the inspection:

On every wash: No matter how safely you drive your bicycle, there is always a risk of breaking a carbon frame. So, you can inspect your frame after every wash to be sure that everything is working perfectly.

How to inspect?

Look closely for any scratch or a deep cut on your frame.

  • If you don’t find any, your frame is probably good to go. But in case you find a scratch or a dent on your frame, it is better to observe it closely. It can highlight the cracks in the bike frame.
  • To ensure it further, you can tape the suspected area with a coin. You’ll hear a dull thud when the frame is broken. You can even push it a little to analyze the softness of the bicycle frame from that particular position.
  • Besides, cracks around pivots and bearings are prominent on the bicycle frame. So you must specifically inspect these areas.

A detailed inspection would be required in case of a crash. Apart from performing the above steps, you must:

  • Pull out the seat post and look for any issues.
  • Shifters, brake levers, and bar tapes can present the problem points; make sure to analyze them in detail.
  • In case you have carbon wheels on your bike, you might want an expert to have a look at them as well.
