Well I upgraded to these from the Time 4 Expresso's and they have not let me down yet! While I don't just mash it out or full out sprint alot these pedals when I do hold up with little to no flex! To be a carbon pedal they sure feel very stiff. I love the ease of entry and exit of these as well as the float. Hard to say if I would ever go to anything else after riding these. If you need a good platform with minimal weight these may be what your looking for. Not to mention they add some color to the ride for sure. My only issue is the plastic tension adjustment screw. WHy why why???? They should have used an all metal stainless for this. Such a small piece that the weight would have never been noticed. Oh well, as long as it holds I will not complain.
