Brett S wrote a review of Shimano PD-M530 MTB SPD Pedals on August 29, 2012
What do you expect? For less than $50 bucks you get less than $50 performance. This pedal reminds me of why I stopped riding SPDs years ago. I had hoped that Shimano had made significant improvements over the years but I guess that just isn't the case unless you get their higher end pedals. For the price they are a good option for recreation and cruises but not much more.
