What are the recommended procedures for adjusting pedal tension on flat pedals to optimize power transfer and comfort, and how do the various adjustment methods (e.g. screw-based, clip-based, or platform-based) impact the overall pedaling experience? Are there any specific tools or techniques that can help ensure a precise and reliable adjustment, and what are the key factors to consider when determining the ideal tension setting for a particular rider or riding style? Furthermore, how do adjustments to pedal tension affect the wear and tear on the pedal platform and surrounding components, and are there any best practices for maintaining and servicing flat pedals to prolong their lifespan?
