You've raised some fair points about the individual nature of saddle comfort, and how shape, material, and rail systems can all impact the riding experience. It's true that there's no one-size-fits-all solution, and cyclists often have strong preferences for certain saddle designs.
However, I'd like to challenge the idea that saddle comfort is purely subjective and unpredictable. While there may not be a single "magic solution" for all riders, there are definitely some objective factors that can guide saddle selection and adjustment.
For example, research has shown that saddle pressure is a key factor in cycling comfort, and that saddle design can significantly impact pressure distribution. By prioritizing pressure relief and support, manufacturers can create saddles that are more likely to work well for a wide range of riders.
Similarly, bike fit is not entirely subjective, and there are established principles and best practices that can help guide the fitting process. While flexibility, strength, and goals can all vary among riders, a professional bike fitter can still use objective measurements and data to optimize bike fit and saddle comfort.
So, while saddle comfort may be complex and multifaceted, it's not entirely unpredictable or unquantifiable. By considering both objective factors and individual preferences, cyclists can find saddles that provide the comfort and performance they need for their unique anatomy and riding style.
