Q Rings

As a doctor, I am frequently bombarded with new products that in theory are better than the old ones, and the sales reps will give me lots of reasons why their product should be better but I won't beleive any of it until they show some real world evidence that there is a benefit.

Similarly with these rings, irrespective of what the theory, the anecdote, the wind tunnel or the power meter says, I want to see some real world data, comparing to traditional rings in a scientific way before I believe any of it.

But surely real world data is impossible to get because it involves a human rider using both and that rider is another variable.

Have they tired? If they know which ring is fitted are they (even subconciensly) modifying their pedalling technique because they expect something to be different? Etc etc etc...
