As Pete said, the A520 SPD provides broader foot support that I find more comfortable on longer rides. The step up from that pedal is the A600 http://tinyurl.com/3r7dsn9 though I can't tell the difference between the two when I am riding.
I like the A530 on my touring/cargo bike. If I start to feel a hot spot, I flip and ride the platform side for a while and it cures the pain. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
