Oval Chain Rings...

Anyone swapped to an oval chain ring?My friend says they make pedaling more fluid and are easier on the knees.

Had one on my Trek MTB and loved it but it might be a wasted effort to put one on an ebike. The PAS system pretty much eliminates the need unless you use your electrics sparingly or not at all.
