What are the different types of bicycle trailer axles available in the market and how do they impact the performance and stability of a bicycle trailer?

There are mainly two types of bicycle trailer axles: rigid and flexible. Rigid axles provide better stability and control, especially on rough terrain, but can be less maneuverable. Flexible axles offer smoother rides and better handling on turns, but may not be as stable on uneven surfaces. The choice of axle type can greatly impact the performance and stability of a bicycle trailer depending on the intended use and terrain conditions.
