so, i was debating over getting another set of pedals from speedplay and i came down to either the x2 or the zero stainless. i went and bought the x2 because i wanted my pedal to be as simple as possible. the only difference is that the zeros have adjustable float whereas the x's don't. but i could do without the extra features since im fairly comfortable with the x5s that i have already been using for the last two years. not to mention that i have thread here about me loosing a pedal screw. i would hate to lose the float adjust screws too. do you think it was a good choice for me to have picked the x2s over the zeros? or do you guys think i'll like the zeros more? anyone lose the float adjust screws? has anyone had knee problems with the zeros? are the zeros just as easy to get in and out of as the x's. not that im regreting my buying decision but i would like to have some pedals that look more than just like a lollipop....something a little more techy looking without sacraficing the ease of use. and no, im not going to change to anything other than speedplays. thanks!

1. I've had Speedplay cleat screws move on the cleats (use loctite) but I've never had the float adjustment screws move at all.
2. Beebops may solve your problems as well, although I am not sure if they are as simple. I do think that the zero cleats are a simpler design than the X series. However, the x cleats aro not compatable with the zero cleats.

You made the right choice, don't even look back. My wife and I both ride X-1's, but the X-2's are the best dollar value.
I see no reason to limit float except for people who have a serious long term problem with the rear of their shoes hitting the crank or chainstay. First time Speedplay users often have a temporary problem with their heel hitting brushing against the crank but this usually goes away after a couple of rides.
I've had adaptor plate screws loosen but blue Locktight fixed that.

On the Speedplay website, they admit that the Zero is harder to get in and out of the cleat. And I agree. I have the Zero stainless and been riding now for over 600 miles. The X-2 for a approximately 15,000 miles.

I never had any knee problems so I can't say one is better than the other.

The adjustable float isn't the only difference. The clip design on the Zeros is different, which makes the engagement more precise feeling. I have both X's and Zeros, and I prefer the feel of the Zeros. They also seem less succeptible to debris, but neither pedal is great about that.

The price difference between an X and a Zero is only like $10, which isn't much. I think the two differences I mentioned are worth that $10 too. Don't get me wrong, the X's are great pedals. I just like the Zeros a bit better.
