Shimano 540's. Eggbeater cleats wear out too quickly in messer use, and spring tension is too slow for heavy skips.

I'v mixed opinions about ATAC's though - they supposedly jam bit easily and sometimes do not open, so if you are hopping on and off as in messenger riding, they are not the best option. Still - no first hand experience on those.

I'll give TIME Impact road pedals a try come summer.
