I got a few pairs of these, i think they are meant to be RACEWORK. The carbon I think is a decal. But they are lighter than my Garmin pedals so who knows.
Have only used for 350km over 5 rides or so, but i've done a bunch of 1000W sprints, they clip in and out easy, and you can adjust the tension (havent tried yet, but you can, there's a bolt).
Got them on Alibaba for 14 usd a pair with a pair of cleats. That's w/o shipping.
I've also been using Chinese cleats for years, the type with a bit of rubber and not just nylon, they're great. They really are consumable, it's probably what i change the most often.
