Bought this set of pedals at REI a couple of years ago and before even taking them out of the box decided not to use this type pedal. Paid about $100. for them and the only time they have been out of the box is to make this post. I don't know much about pedals so please let me know if you have questions.

the box says 428g per pair, composite inner body, aluminum outer body, stamped steel wings, steel spindle, internal bushing and cartridge bearing, dh/ race pedal. Designed by Crankbrothers.

Let me know if I can help
