No - those rings - I was trying to be funny - and failed.

I don't know if you heard it in the video (I may have cut it), but the kids in the back seat were commenting on how "that guy is so strong he was going up the hill at 70rpm and hammering".

I often wonder about non-round rings. Trainer uses them. World class guys go on and off them.
If you have a crank based power meter I'd be curious if they give the same readings as round ones. The plan Sunday was to put a PT on the rear of our rider, Bo, who uses them and see how it compared with the SRM numbers. But Sat plans changed.
