The Idea behind Rotor
The thought behind the Rotor Q-Ring/QXL-Ring chainrings is a simple one: every pedal stroke encounters a dead point. This is where the cranks are perfectly vertical. You can't exert any meaningful power at that point, so you'll want to get past it as quickly as possible. Rotor Q-Rings/QXL-Rings have fewer teeth at this point, allowing you to get through it quicker. They then provide you with maximum gearing during the part of the pedal stroke where you can provide the most power. This theory helps you get through the dead spot quicker, meaning you loose less power when you try to reach your optimal power band. This increases your pedalling efficiency, and reduces the amount of lactic acid you produce as well as your fatigue levels.
The technology behind Rotor is all about efficiency. Rotor believes that their product might not necessarily be faster of themselves, but that they help you generate a more efficient pedalling motion, thus reducing the net time it takes you to cover a time trial for instance.
Various scientific studies have proven the positive effect of the Rotor Q-Rings/QXL-Rings by now. Maybe even better proof are the numerous victories achieved in the pro peloton using Rotor Q-Rings/QXL-Rings.

In a word super
Product just works well Does what it is supposed to do
Pros & Cons
5 / 5
Small plus
Rounder pedalling despite the oval shape. Increases leg rotation speed. Allows you to put in a few extra watts, but when there are none left...
5 / 5
From 30 nawr 32 oval good choice
Takes a little getting used to but then great pedaling
5 / 5
Excellent quality and price. Good alternative to sram.
I recommend this oval chainring, which fits perfectly with my sram xx1 11v drivetrain. Very good price
Pros & Cons
2 / 5
Poor drawing - is it going to eat my chain?
No installation problems, except for a not very precise offset (I had to add a washer to the chain guide on my Scott so it wouldn't rub). More seriously, a lot of noise when pedalling with a new 12v X01 chain (well lubricated with 'rock n Roll' before fitting), with a sensation of resistance when pedalling. There's a problem with the machining or design of the longitudinal profile of the teeth. I'll try another rando, but if it doesn't improve, it'll be taken off the bike.
