DZero/Praxis Buzz owner.

DZeros come in two versions - HB and NHB. They are different and cannot be converted later.
Praxis Buzz rings can be used on HB OR NHB cranks - two different positions for the pin and a blanking plate to cover the hole that is not being used.
Red cranks and rings are HB only.

I’m planning on purchase the praxis buzz chainrings to use on my quarq Dzero Sram etap, I’m using the red chainrings, do you think the praxis are better and smoother?
Thank you

Red chainrings work better with Red front derailleur. Had opportunity to buy second hand brand new Praxis pair for 40€ and wanted to test them but I don't think so they are even near worth of 140€. Little bit overrated tbh.

I chipped one tooth of the X-Glide 50T and I replaced it with another X-Glide... if that happens again I will try Praxis buzz. Now I'm a bit disappointed buying hidden bolt over NHB...

the dzero spider for HB and NHB looks exactly the same, what is the difference?

The splines are offset and they are keyed differently.
