I tried Rotor Q rings. The change reminded me of when I got a new tennis racket or golf clubs. There seemed to be a bump in performance and then the old me emerged. I did some hill climb races and thought I was slower. That is the kiss of death to any change.

Since I am a trackie, and oval rings are not feasible, I thought why develop any neurology that is different on the road?

The oval rings change the gearing slightly and crank based power meters are off about 3% due to the change in tangential speed of the oval rings.

Also, shifting was never great on the front derailleur.

I took them off and still have them. Occasionally, I think about trying them again. I talked with my mechanic about putting them on and he had a look of terror in his eyes at the thought of adjusting the front derailleur to work properly.

Try them and see if they work for you.
