What are the benefits of using a bike with stem extension for long-distance cycling?

Using a bike with a stem extension for long-distance cycling can provide several benefits. It can improve the rider's comfort by allowing for a more upright riding position, reducing strain on the back and neck. This can also help to alleviate pressure on the hands and wrists, making the ride more comfortable overall. Additionally, a stem extension can improve aerodynamics, making it easier for the rider to maintain speed and efficiency over long distances.
