A buckle usually occurs on the front wheel as this is the wheel that tends to hit the curb with the most force. You might notice a buckled wheel when the wheel rubs against the brakes as you ride your bicycle. Fixing a buckled is often called “wheel truing.” The process is relatively straightforward, and you only need two tools to fix the problem.
You might have to replace the spoke if it is badly damaged.
Repeat steps 1 and 2 for the other side of the wheel.
Repeat steps 1, 2, 4 and 5 to fix the other spokes until the buckle is repaired.
