Does such a thing exist, or is it snake oil and I can use the 30T 104BCD Hope retainer ring I've got instead?
I'll be running it with an XO1 11 speed mech. Will the chain need to be shortened?
Currently using a 34T RaceFace N/W ring. It's fine for my local trails, but my style is more "sit and spin" than "grunt and power" up the climbs!

Google seems to say they are, whats the BCD?
Do the X)1's have the removable spider? If so then direct mount is an option.
I have RaceFace Turbine cranks. RaceFace site seems to suggest 104BCD which means my Hope 30T should be ok. Should probably measure the BCD to be 100% sure.
So there's no such thing as an 11 speed chainring?
You'll be fine with any narrow/wide ring, so yes, your Hope Retainer Ring will be fine.
Yes, you will need to shorten the chain (if it's currently exactly the right length)
Kind of, but 11sp single rings are also compatible with 9 and 10sp, so all of the ones I know about are 11sp narrowness.So there's no such thing as an 11 speed chainring?
