Sideburnswrote a review of Crank Brothers Egg Beater C Pedal on January 12, 2009
They work, I've got hundreds of road miles and hundreds of trail miles on a pair and they are still going strong.
I typically ride Mallets for the extra support, but use these on my Scott Sub 20 and my SS 29er when I'm not standing on the pedals for hours. They've held up well so far.
Crank Brothers service was excellent when I needed a set of Mallets repaired.
