Dunno, but I'm thinking of them more as a small solid pedal than a cageless pedal.

I ordered them for my Carryme to shave some weight and reduce the width of the folded bike (pedal width is the limiting factor on the folded size of this bike). Since I've been happy with the ride quality of even the stock plastic pedals, I don't think I'll be disappointed here.

Besides quite a few folder fans (including Strida designer Mark Sanders) have advocated the use of plastic nonfoldable/nonremovable children's pedals. These can't be too different from that, except being stiffer, removable, and with better bearings. And I figure if they suck I can always chuck a few of the bearing cartridges (there are 3 per pedal) and drill some holes and have some real ultralights.
