Whats the justification for trail builders prioritizing sustainability when it comes to surface materials, considering that it often results in a less grippy and less durable surface, ultimately affecting the riding experience and potentially increasing the risk of accidents? Are the environmental benefits of using sustainable materials truly worth the compromise on trail quality and safety? Shouldnt the primary concern be providing a surface that allows riders to perform at their best, rather than sacrificing performance for the sake of being eco-friendly? Is it possible to find a balance between sustainability and performance, or are these two goals inherently at odds when it comes to trail construction?
