Carbon Chanrings Unionjack /Cybrei ETC

[Sander2177]

Anyone know who manufactures the Unionjack carbon chain rings?
Seen them on Aliexpress reviews look good and yes they look like Carbon Ti but i need 110BCD 4 arm

I have used carbon Ti on DA 12 speed and shifting is good.
Also considering Cybrei but I need someone who knows what the shifting is like

The ones you linked are 1x and the teeth are also carbon so theyre a waste of money

Marginal gains from the chainrings self lubricating with graphite as they quickly disintegrate?

Ok link deleted. Seem like they are Brompton only, shame looked promising. 

Will consider the Cybrei rings, asked why they have paired 54 with 38t and they said for climbing.
IMO that's what 52/36 and 50/34 are for,  54-38 is a bit of a jump.
Rather have there meta aero rings in 54/40
