Browsing the CX Magazine website, I came across this information on a promotion Crank Brothers is running on a few of their pedals.
The skinny: you send them ANY clipless pedal and they'll sell you a new pair of Egg Beater 3, Candy 3 or Mallet 3 pedals for $60+ shipping. Add the CX Magazine code, and you also get a pair of shoe shields.
I've got a pair of the Egg Beater 3's and I can tell you that they are a nice pedal. As of 2011, the CB 2, 3 and 11 lines have better seals than older CB pedals did (and, I guess, better than the entry level models still do). The upshot of this is that they don't need to be rebuilt/regreased all the time the way the old pedals did. I've put about 2400 miles on a pair of Egg Beater 2's and about 750 miles on a pair of Egg Beater 3's, including seven or eight muddy CX races on each of them, and they're still spinning as smoothly as the day I bought them.
Anyway, enough shilling from me. I promise neither Crank Brothers nor CX Magazine is paying me for this or asking me to do it. I just thought this was a great deal and wanted to pass it on.
