This thread is not reassuring me about going clipless. It seems overwhelming in terms of choices about pedals, how to adjust them, and so on. How can something that should, it seems to me, be pretty simple get so complicated?

Now I'm (still) worried about falling over, and worried about making my knee problem worse, and buying/regretting the "wrong" pedal, and I'm getting overwhelmed with all the well-intended advice and opinion. (This is about me, not you... )

I have a headache.

Maybe that's why I like platforms so much. They are no-brainers. Kinda like me.
