I used to be a die hard Crank Brother's Egg Beater fan. They clipped in under and condition and were light. I loved them. However, I did not notice the significant power loss I was experiencing with the high degree of float from the CB pedals. Once I switched to the Look Quartz pedal my power increased 12%. This was confirmed on a powertap and edge 705. The only change was the pedals. Besides the significant power increase these pedals have a vary similar entry and release. I had NO PROBLEMS entering in all types of conditions, mud, snow, or dirt. I have now switched all three bikes to the Quartz and have made paper weights with the CB. Also, been ridding these pedals for a year without the need to service the spindles. Amazing pedal!
