So I ran oval on all my bikes for about 3 years and have recently gone back to round due to availability and not feeling much of a benefit with oval. Also I looked at the cycling Dynamics profile from my favero Assioma pedals and when I would stand on a steep 10%, my power zone switched completely out of the optimal oval zone of the chainrings. I can include an image of what I’m talking about if anyone is interested.
Also the studies out there do not show much of benefit if any but from the studies, it doesn’t reduce effectiveness so if you like the feel of them, then use them, if not then don’t. Pretty simple.
