Carbon chainrings

[glepore]

Any actual experience with something less expensive than Carbon Ti? Looking for 50t 110 for a 50/34

What are you trying to achieve? Because afaik, carbon chainrings make essentially no sense, so if we know what you're solving for (stiffness, weight, vibe?), maybe we can help.

Hi Serge. Weight primarily, seems most will cut off around 30g. And of course style, lol. Don't seem to be a ton of options out there, generally don't trust the "Union Jack" stuff as a brand.

Agree with Serg_K. I have the Cybrei Meta aero chainrings, and they’re a smidge lighter than the Cybrei aluminum ones nothing in it! But honestly, theres no difference in performance. I bought them because they just look better aesthetically, on the Cybrei crank. I could have used my DA 54/40 but i wanted a 38 to see how it was with the 11-34 casette for climbing.
There is nothing else out their that i now of but Carbon Ti.
Gemini are developing 2X rings like there 1x Ridgel gravel rings but there obviously will not be cheap and cheerful!

pointless, unless you want it to have a completely flat profile for aero/aesthetics, just stick to dura ace. Best shifting and virtually no weight penalty against carbon

I wouldnt ride carbon teeth because they will wear out. I wouldn't trust some unbranded alu / steel teeth ring bolted to some carbon spider because that sounds niche AF, at which point it's probably expensive anyway. It's not the part of the bike where i'd try to save weight. And presumably, vibe points are linked to the brand, being able "that's the same rotors as Pogi" or some like that.
Can't help for what you're solving for

Is there any lightweight titanium chainrings available? It seems alloy is hard to beat in that regards.

there are boutiques in europe that make full titanium bikes, and they CNC their own cranks and chainrings. Largely pointless, but very nice machining indeed. from memory they make them light. GCN made a nice video on one of these boutiques called Everything You Didn’t Know About Titanium Bikes.
Aluminum is cheap enough, light enough, hard enough, it works well for this application.

pass quest or stone alu- great job!
