I know this should probabley go in the single speed/ fixed gear forum but I figured that the majority there use clips and straps and not $250+ clipless pedals.

My question is does anybody know the width of the Dura Ace pedals? I would like to compare it to my current pedal setup (which is platforms with clips and straps). I'm worried about pedal strike, which happens to me on occasion. I have never went down because of it, but I would rather not scrape up a pair of DA pedals, although I know that it will happen eventually. Knowing this I am also wondering how durable the pedals are, if they can take an impact without being damaged.

I'd like to use the same pedals for my road fixie and my track bike. Is it ok to take pedals on and off and switch them to other bikes? I would be riding the track 2-4 times a week.
