Hi Everyone,

I have a new trek emonda slr framekit and a sram red axs upgrade group. (Without crankset)

I need a powermeter crank and my lbs gold me that a sram red axs 172,5 46/33 is not currently available in Belgium.
So my question is now, is a rotor inpower with aldhu chainrings compatible with the sram red axs 12 speed chain?

Sportive greetings drom Belgium

There are AXS compatible chainrings from Rotor, your LBS should know that.

Absolute Black also and are stiffer and better shifting experience...

I installed one with 48/35 round rings and it fit perfectly, install and forget, no adjustments needed.

There is an even cheaper solution...

If you own a Quarq 107mm spider, you can build it with Rotor 107mm Qrings. They have been released last September.

Here's a picture with the standard spider (Force-Red AXS cranks).

It's available in 2 sizes 48/35 and 50/37. Optimized for AXS flat top chains. Quarq is a much cheaper than tranforming the wole crank with Inpower/Inspider.
Rotor powermeter is a good option for Qrings adjustment: calculation of the best position of the Qrings on a Rotor Axle/spider.

Thx Folks for the answers.
That's all good to know :thumbup:

I don't like the look of the aero chainrings that are compatible with the axs flat top chain.
I do like the rirect mount chainrings (wide range 46/30, 48/32.........) Also i prefer the looks.
Anybody knows the direct mount chainrings works well with the flat top chain?

No direct mount offer for 12S Sram AXS yet from Rotor. 11S only.
Don't know if they wirk out well together.
