Last week, the right foot SPD - M515 - on my commuter started emitting a metallic click when it's under load; e.g., pulling away or when I'm in too high a gear for the situation. I didn't think it would be wear & tear, as I always unclip the left SPD at any stop. But then as the GLW smugly pointed out,
the right pedal gets more abuse as that's the one I pull away on. I've had this set for a fair few years, so time for a new set, or just swap them for a set from one of my other less used bikes - ?
