I have a new touring bike and I’m thinking of going with platform pedals. I have used Shimano pd m324 on my previous touring bikes, so I can click in on one side and a platform on the other. But looking at the current platform styles, I think they have a larger surface area. Looking at a Shimano pd GR500 or similar. Who uses platform and why? What are the advantages you get from them and what are the drawbacks? Thanks!
