These are by far my favorite cleats for any bike that I have SPD pedals on. The multiple angle release makes them much easier to unclip from the pedals then the standard cleats. This makes these much safer to use that I highly recommend them for beginners that are converting to clipless pedals. I have never had a failure to release in any situation which required my to do it quickly. This includes mountain bike riding where getting out of the pedals in a hurry is really important.
