Carbon Fork Test May Prevent Bicycle Accident
Tagged Under : Bicycle accident, carbon bicycle fork, kentucky
A couple of months ago I wrote a blog on carbon fork failure and how that failure has the potential to cause a serious accident. The unfortunate fact is there have been cases that have resulted in paralysis. Since then I have spoken with several bicycle mechanics about the subject. When I had my bicycle tuned last week and new wheels put on (by the way I highly recommend the Mavic Kyserium Elite wheels) I had to ask the bicycle mechanic if there was any way to check my carbon fork. After seeing a fork that failed I was a little paranoid. I had looked at my fork for visible defects and ran my hand over the fork to see if I felt any cracks. I didn’t, but felt that there was another way to see if my carbon fork had any signs of fatigue.
I have been told that you can test your carbon fork by removing it from the bike and tapping it with a metal object, such as a knife. You tap up and down the fork. You are looking for a clear pinging sound with no dull sounds. Also, I am told that consistency is a key. Any differences in the sound may indicate a problem. This is a test that is possible to perform at home, although I would suggest having your bicycle shop perform the test. I am much more comfortable with a professional looking for problems, whether it is an attorney, an engineer or a bicycle mechanic.
If your bike has hit a pot hole or a curb you should have your carbon fork examined for a crack or defect. This type of stress may cause carbon fork failure. Be careful and have a qualified mechanic examine your bike and your carbon fork whenever you have encountered stress such as this. It may only take one hole or curb to damage the integrity of your carbon fork.
If I am flying down a hill at 40 mph plus I want to be absolutely sure my bike is in tip top shape. I trust a qualified mechanic at a bike shop much more than myself when performing this test. The primary goal is to prevent a bicycle accident. Proper maintenance is the key to keeping our Kentucky roads safe. I encourage everyone to ride safe and smart. Make sure you have equipment that is in good shape and make sure your carbon fork is not prone to collapse.
