A derailleur hanger can break due to a variety of reasons, including impact from a crash or hitting an obstacle, improper installation or adjustment, or simply wear and tear over time. The hanger is designed to be a sacrificial part, meaning it is meant to break in order to protect the more expensive components of the bike, such as the frame or the derailleur itself. Additionally, the hanger is made of a relatively soft material, such as aluminum, in order to absorb impact and prevent damage to the frame or derailleur. Regular maintenance and inspection of the hanger can help prevent breakage and ensure smooth shifting performance. **

To search for a suitable derailleur hanger, you can start by identifying the make and model of your bike. Once you have this information, you can search for a compatible derailleur hanger specific to your bike's make and model. You can check with the manufacturer of your bike or visit a local bike shop to find the appropriate derailleur hanger for your bike. Additionally, there are online retailers that specialize in bike parts and accessories where you can search for a suitable derailleur hanger. **

The clothes hanger was invented by O. A. North in 1869. North was an employee at a factory in Connecticut, and he came up with the idea of bending a wire into the shape of a hanger to help keep his coat wrinkle-free. His invention revolutionized the way clothes were stored and is still widely used today. **
