Just recently discovered these.
Without even thinking my brain is saying get them, just pure lust.
I was thinking I would eventually replace the ugly S Works chainrings with Praxis but those don't look so great either.
If the shifting is as good as the S Works rings with my Ultegra Di2 I would be more than happy.
I weight 138 lbs so I don't know if flex would be an issue. Crank is S Works compact 34/50
Not much info on these so please help if you have them.

Read the thread praxis or kcnc cobweb?

Did read that. Can either conclude they are just ok or too flexy.

I've used them on several bikes with Di2 and had good success with them.

I've used both but neither on DI2. Personally, with mechanical systems I would only use Dura-Ace, Campy, or Praxis rings. Nothing else has ever come close to those three in terms of performance. KCNC just couldn't shift as smoothly. Maybe with electronic stuff it doesn't matter, though.

I think you are about to get dinged for those spacers on your steering tube.

There's a new version of the KCNC Cobweb chainrings designed to be stiffer....I also would recommend Specialites TA. Personally I'm using Tune chainrings and the performance is very good with Campy EPS.

I have a set of 130bcd on rotor cranks on my r5 and they are very flexy. I love the look, price, and weight (they go very nicely with M5 brakes!), but I would never purchase them again. Shifting is very poor and I get noticeable flex in the big ring when getting on it. I am a 175 lb cat 1 though, so I don't know if you would have similar issues....
