According to the product specialist

Pros
You can mount your Rotor chainrings on a Shimano crankset at once.
No need to buy a complete new crank set.
This chainring is carbon-reinforced, which ensures it's rigid and lightweight!
High durability due to the special coating.
-
Thanks to the modular structure of the Rotor crank arms and chainrings, adjustments are made quickly!
The NoQ chainrings are made of the very sturdy and durable 7075 aluminium.
Cons
An original chainring is the best.
