I have been using Speedplay frogs, but the cleats wear out VERY quickly. I love the float, but the release problems are ridiculous.

This chart is helpful:

I started using SPD cleats again, but my knees hurt. Apparently, there are SPD cleats with float, the ones without float indicate a "0" on the bottom of the cleat. However, mine is a float, but it doesn't feel like it.

I'm wondering what you all are finding works for you. I'd go back to the road version of the speedplays, but I had a set, and they are very difficult to get out of on my Bachetta recumbent bike (the angle).

So, I need some ideas around my SPDs or perhaps switching to another system.

Thanks for your help!
