Why we choose aluminum
7075 aeronautic-grade aluminum alloy offers superior physical properties with which to craft components like our signature Q-Rings, REX 3 and 3D24 cranks.
- ALU CNC
Manufactured with the latest technology
Computer Numerical Control (CNC) machining provides a precise and consistent manufacturing process. This is especially important when it comes to crafting bike components in order to ensure flawless funcionality with respect to all the parts working together. Equipped with the latest CNC resources, ROTOR parts are precisely machined to within a hundredth of a millimeter.
-DIRECT MOUNT
The shape of the axle lets you position independently both cranks and spider or Direct Mount, and thereby change the relative orientation in order to adapt to the optimum orientation of each user.
-OCP MOUNT
ROTOR’s exclusive patented technology “OCP Mount” refers to the pedalling’s biomechanical optimization when you are using Q rings or other oval chainrings; this lets you adjust the orientation between chainrings and cranks by one step degree.
The shape of the axle lets you position independently both cranks and spider or Direct Mount, and thereby change the relative orientation in order to adapt to the optimum orientation of each user.
The multiple positions offered by “OCP Mount” technology let a fine adjustment of the OCP (Optimum Chainring Position), because so far you could position the Q rings in 5 exclusive OCP points, in 4 by 4 degrees, with a usual spider. In this way, with the OCP Mount technology, any oval chainring can benefit from an OCP with micro-adjustment to increase the performance of your pedalling and your knees health, or even to modulate the traction in MTB and Cyclo-cross.
Adjust perfectly your chainrings to your pedalling style with the ROTOR’s “OCP Mount”.

Easy to install and easy to replace if needed. I have multi bikes fitted with these chainrings and in different sizes. They are all good quality and work perfect, I like the one piece and the direct mount som much easier than the spider with the open bolt/nut configuration.
Super compact

I was looking for a crank that can use a 46x30 chainring, and there was a perfectly round 46x30 that was not sold domestically, so I bought it. I'm currently using a Sugino 46x30 chromoly disk load. Other carbon roads I own are 50 x 34. For me, 46x30 is the easiest gear ratio to use, as I can lower the overall gear ratio unless I'm going to run hard.

Post brexit, delivery takes a bit longer, but tracking was provided. The chainrings are a replacement for a worn out set which had lasted well. They are light and beautifully made

The dishes came to me very well and quickly, as usual. They are of very good quality and very light, and provide a lot of rigidity compared to a normal chainring with a spider system; assembly is not complicated at all with the tool provided by the rotor itself ... Great product.
Good rings

12 speed compatible?
26/01/2024
Richard
Is the Rotor Direct Mount Round Ring NoQ Chainring on your website compatible with a 12 speed groupset? On the RotorAmerica website the chainring set is listed as "Compatible with GRX, 9, 10, 11, and 12 speed groupsets". Is this a different product than what is available in America, or the same product with a difference in description?
Answer of Robert
I have been using both the 39/53 and 34/50 sets for over a year and find that it works as good or better than the 12 speed DA Shimano chainset. I use it with a hot waxed ybn gold chain which runs much smoother than the DA chain as well
Answer of Chaz
They are round chainrings (NoQ).
Answer of kim
from my personal experience , yes no problem with sram 12 and shimano 12

Hello, do the cymbals come with the pedal clamping tool?
Answer of Richard
Hi, there is no pedal clamping tool included. However, this chainring has been great and I’m very happy with the performance R.
Answer of Chaz
If you´re referring to the chainring , they mount in between the rotor cranks and the bottom bracket . Tightening the crank arm holds the chainring in place .
Answer of kim
Hello , NO ! What u see is only is what u get !

Hello, is it compatible with the Sram Rival Etap Axs 12v groupset? Thank you
Answer of Watit
I think it’s not compatible because sram etap has a different number of teeth on the outer chainring and the inner chainring is 13teeth. When you change your front derailleur from inner chainring to outter chainring it might be difficult, if not impossible.
Answer of Chaz
Yes . They work with 12s as well .

Hi, Just checking that this chainring is compatible with my 11 speed time trial bike. Also wondering which Rotor Road Aldhu Axle I would need to purchase for this chainring? I am after the 50/34 chainring- is 30mm axle the correct one? Will this be compatible with Rotor ALDHU 155mm Road Cranks?
Answer of HsinMao
The rotor 50/34 direct mount chainring is compatible with rotor 30mm axle, i also believe it works well with 155mm cranks.

Hi, good. Is it compatible with SRAM Force AXS cranks?
Answer of HsinMao
No it´s not, according to Rotor official website, it only works with Rotor axle.
Answer of Clément
Hello No it is not compatible with sram force axs cranks Sportivement
Is Axle diameter a consideration?
11/11/2022
Matt
Rotor Aldhu cranks support 24mm and 30mm axle diameters. Are there specific chainring sets for each axle diameter i.e. 24 or 30 mm models? or are the chainrings independent of the axle diameter and therefore compatible with either axle specification?
Answer of tai
It’s independent from the thru axle. Just get the right thru axle. Cheers

Good afternoon, can you tell me if the bcd of this product is 135mm?
Answer of Benjamin
Hi, no issue because it is a direct mount chainring
Answer of Chaz
Hi . This chainring does not mount on a separate spider . It´s a one piece design that has the spider machined into it so you have to use a rotor crankset that doers not have the spider built into the crankarm . The chainring is the same design as the Cannondale SpideRing that is direct mounted to crankarm .
Answer of TY Chua
This is direct mount chainring therefore there’s no bcd (bolt circle diameter).

Hola estos platos serian compatibles con Shimano Ultegra 8100 de 12v gracias
Answer of MIYATA
It can be used with the Ultegra 8100. It can be operated without the chain falling, but there are some places where it is a little difficult to enter when gearing up with FD.
Answer of Peter
Hola creo que estost platos serian compatibles with Shimano 12v.
