I’m planning on buidling my TT bike as 1X with my 110 BCD P2M spider. I would put a 52 or 53T aero round chainring. The first brand I find is Rotor NOQ Chainrings. The inside machining ribs look like they would bring some drag though. Any other options out there ? I see the Drag2Zero chainrings also. They’re expensive…

I’m gonna go with a “no†on that one.
Garbaruk, Pyramid Cycle, Stone, Aerocoach and many others once you get up to 52t size. I got a Wolftooth ring and a flat carbon cover by AldenCarbon. Two brands I know I can trust.

Praxis.
I run the forged Praxis road Aero 52 - 110. Not sure if that works with your 1x set up or not but it found it was a good option when I went down to 110.

You can’t do 1x with an odd number tooth chainring, at least not with a narrow-wide which you need.
I just ordered a 56t 130bcd and a 50t 110bcd Garbaruk chainring for mine and my wife’s Omnis. I think they should be here next week. I can post some pictures and let you know how they are when they’re here.
Ok, that’s cool. I have Praxis Works on my bikes and like them a lot.
I didn’t find an aero chainring with 110 BCD on their website though…I’ll check again.

I have rotor 53/39 110BCD on my Power2Max.
Look under “Road†(not TT) and you will see the aero option.
