That's not quite the same as the Zayante Carbon. It's the cheaper version and you can buy that the same on Praxis' web site. They have NO single ring in that model but it is a DM so you could crap-can the rings/spider and go with your OEM chainring. You won't find many decent chainrings for $50 so, IMO, it's worth buying the standard $300 Zayante and ending up with some variety to try if you need to make a change.

Also, if you buy direct from Praxis, you have 30 days to say "Beat It!" and send it back.
