I had the carbon version of these for a couple of years. When they needed replacing due to a crash I decided to save a few bucks, accept a few extra grams, and buy these instead. Totally worth it. Can't tell the difference between the two. Great pedals all around.
I use these pedals on my Calfee Tetra Pro road bike.
Click-in is easy and secure. I've experienced zero squeaking from the cleat-pedal interface, which I hugely appreciate, and the pedal bearings spin very smoothly. So far, these pedals seem to be a quiet work-horse component that functions perfectly.
