Rotor makes an Aero 52t 110bcd one called QX1


Aerocoach Arc makes them as well in 52, 54etc in 110 or 130, very slight ovality to them compared to Rotor Q-Rings.


I have not seen an absolute black one besides the direct mount

Aerocoach Arc would be my recommendation. Be a month I'd guess before you'd get it in the states.

i have one that is from http://www.fibre-lyte.co.uk

Absolute Black makes one thats Sram compatable
Its a direct mount. I have one if interested.
I personally ended up going with Rotor Ovalized narrow wide.
1x is sweet.

WATTS UP!!

I've tried just about all of them. Garbaruk is my favorite, although the quality control isn't great. I've had 2 of their rings that I had to take a dremel tool too. But the chain retention is great and the chainline is perfect when put in the inner chainring position (chainline is within 1mm of the middle cog on my crit bike). My 2014 venge just barely has enough clearance for the 50t ring in the inner position.

I just got the rotor 50. 50x11 is big gear. Not sure I love the 1x. That cross chain in the 27 and 30 can't be too efficient. A 1x11 is really a 1 x9.5.

Wait, you are cross chaining in a 1x set up??
