I have a SRAM 10 speed MTB 120/80 spider on my Zayante carbon cranks (with TA chainrings)

I'm going to guess that the SRAM spider is an X0/X1 spider (intended for carbon cranks)? X9 alloy cranks have a narrower profile, and the "recess" in the spider is narrower. I have a Praxis Doon (carbon) crank and it is too wide to fit an X9 spider. It looks like it might fit an X0/X1 spider, but I have not tried it.

Likewise, SRAM Force road spiders have a wider recess for SRAM carbon cranks, and SRAM Rival spiders have a narrower recess for SRAM alloy cranks, so I suspect an SRAM Rival spider may not fit a carbon Praxis crank.

This is what I have on the Habanero.

What is the situation with Dub crank arms on a BB30 or GXP spider? I have two Quarq cranksets I want to convert from 175mm to 170mm for fit purposes. One is BB30 road, the other is a GXP mtb dfour. I’d happily buy the BB30/gxp arms but Dub seems to be all that is available. Thanks!

On the road side, for 12spd SRAM has moved to 8 bolt spiders, and from BB30 to DUB spindles (GXP spindles are still available), so just about any DUB road crank will use 8 bolt spiders. But 11spd GXP and BB30 3-bolt cranks are still available, such as these:

Looking around you can probably find them cheaper than this.
