What specific technical considerations, aside from tire pressure and tread pattern, can be optimized to minimize rolling resistance and maintain speed on flat gravel sections, and how do these factors interact with rider position, bike fit, and overall riding technique, particularly in relation to aerodynamic efficiency and power output?
Furthermore, how do the differing characteristics of various types of gravel, such as grain size, angularity, and surface texture, impact the optimal setup and technique for maintaining speed, and what data is available to support the notion that certain gravel-specific bikes or components outperform others in these conditions?
Additionally, are there any empirical studies or real-world tests that demonstrate the effectiveness of techniques such as gravel surfing or hunting for grip in maintaining speed on flat gravel sections, and if so, what are the key takeaways from these studies that can inform a riders approach to optimizing speed on these types of surfaces?
