My Q- Ring arrived late Thursday.
Just one (the large 53t ring).
Got it from the Hostel Shop.
Came with no instructions just in a plastic bag.
I guess if you buy a whole set you get instructions.
Set it up following posts to this thread.
Took it for a test ride and it felt a little Humpty Dumpty.
Rechecked this thread and read more carefully.
Did a readjust cause I missed a post or two.
A discusion back and forth about wich index point to use.
Readjusted, and it really smoothed out. Felt right thought it must be right.
Rechecked thread this morning and a couple more posts got me thinken.
The Creator has a manual, why not check the website of the creator of the Q-Rings
and read there manual.
After reading there instructions, I thought I understood there cryptic instructions.
As many have said you realy have to wrap your mind around there instructions.
I now had it set to large side of ring ingaged at dead spot, small side on power stroke.
Printed out instructions from Rotor and reread this thread.
It was at that time I opened my box of cereal and got the decoder ring out.
Ureka, the instructions finaly made sence.
It comes down to correctly finding your #2 OCP spot, and a couple other details.
This won't mean anything to you if you havent read Rotors instructions.
As it turns out I was only one whole different than the one I had it set to before consulting Rotors manual.
Now as others have said their is a significant leway left to right from Rotors suggested sweet spot.
I am anal about getting it right so I wanted to be positive I was starting from creators suggested sweet spot.
Rotor says a higher ocp # is better for acceleration.
A lower # slightly higher top speed.
Also Mashers (earlyer resistance in stroke) lower ocp #
Knee savers (later resistance in stroke) higher ocp #
In my humble opinion the image of the Black Corsa setup in this thread is correct for a high racer + or - a whole or two.
It turns out my suggested sweet spot is only 1 whole different from Tweetys setup.
(plug for Tweety). If I only had listened to Tweety I could have saved some greif.
But I wouldn't know for sure. Now I think I do.
This is my setup (do not assume it is your setup) Q-Ring 2 003

After only 30 miles my thoughts so far.
They seem to be a definit Knee Saver.
They relieve the force needed to stay at cadence when your knee is compressed.
Resistance gradualy increases as knee is extended.
It also feels like it will be a small performance boost.
I like them. They are pricey, thats why I opted for just one for now.
