Could be a fun thread…

I noticed a lot of new bikes on the market have oval shaped seat post. A couple of manufacturers had started doing that in the last couple of years.

I know head tubes had gone oval for a while. The excuse was “aero”. Put aside the reality of most people not racing probably aren’t riding their bikes fast to benefit much from it, I doubt the aero benefit extends to seat post. More to the point, manufacturers aren’t claiming it for aero benefits either. Bike shops sales came up with all different guesses. None are terribly convincing.

So, I wonder what’s the motivation behind. What have you heard? And are you convinced by those reasons?
