So...I guess this is why you buy the higher-end Egg Beater pedals:

One of the wings broke off today while riding around. The other sides work fine, so maybe I'll keep it on the trainer bike.
I still think these pedals are the best thing for cyclocross. Just go with the stainless steel models.
hate to say it but there's no way I would run those without getting paid a ton of money to do so. the new shimanos just work so well. and even in mud, do a quick pre-release and they are golden and you won't Joey into a barrier.
