Shimano PD-A520 SPD Pedals

Have now selected these for the entire stable. We ride an Erickson tandem mostly, but need compatible pedals on the singles for those rare occasions when one of us can't ride. Like to use a touring or less aggressive mountain shoe Sidi Dominator, etc. when on long day rides or extended tours, and thus we like to have an SPD pedal. This is a light and very serviceable pedal, and the BEST we've found for this purpose. Very comfortable. Can attest to appropriate release mechanism major FDGB fall down, go boom last fall on the tandem, but release worked well. Wish my clavicle and scapula had been as well designed! I now have a new titanium clavicle, but might prefer not... Oh, why only a 4 star overall? Well, these aren't quite up there in shi-shi points. If they charged, like, 3-4 times as much for them, I'd give them 5 stars!
