OK, Another qualified vote for Time ATACs here. I have them because they play nice with my knees. I have some carbon ATAC on the mtb, Aliums on the fixie, Z-controls on the commuter, and the single-sided "road" version on the tandem.

I got the Zs because I thought they'd serve well as a platform pedal when I'm not in bike shoes. Turns out that the best platform pedals are actually platform pedals. Who knew? I would not go that route again. They are also the heaviest pedals you can possibly buy, so they've got that going for them.

I picked up the one-sided version b/c they were on super sale and I figured, what the heck. Funny enough, if you can get these wrong side up, they make a decent platform. Really though, I don't see the point, they're not really lighter than the double sided which I would go with if available at comparable price. Live and learn.

One other consideration: My wife somehow wound up preferring Shimano spd. Life would be a bit simpler if we could harmonize this choice. We have lots of bikes and lots of pedals, but there always seems to be one bike looking for pedals and a spare set of the wrong kind floating around. I think we're in too deep to turn back but there are days... especially when I realized the Shimano make a rather nice spd with a little bear-trap surround that actually does a good job of what I was hoping to get out of the Time Zs, it is ok as a platform in a pinch. My wife has a pair on her extracycle and she likes them.

I also have 2007 Shimano Dura Ace proper road pedals on a fancy road bike. They rock. Road shoes are no fun to walk around in, except for those watching you.
