Ive been riding around on these. Power pedals although nothing to do with measuring watts. Instead they only ratchet in one direction so as soon as you attempt to backpedal your legs lock. Proper lethal too in situations like stopping and putting a foot down and similar to using single sided pedal fixed gear. The idea was that they allow you to pull up on the pedals more convincingly - it may or may not have any merit but a 70 mile ride using them was fairly knackering. Theyre made of magnesium/titanium and have really nice bearings in them but are not lightweight and the cleat design is stupid - the front edge releases rather than the rear ie 90 odd percent of pedal designs out there. This leads to rather an uncomfortable rotation of the foot - heel inwards to release and pivoting the toes down to clip in.
