Why aren't they round? Sure I've seen some that are sort of eliptical, what's the reason?

It's called an Osymetric Chainring. It effectively down gears the bike at the weakest point of your pedal stroke (12 and 6 oclock) and up gears it on the strongest point (3 and 9 oclock).

You seem very angry today.

You are aware you're posting in the cycling forum yes?

Has the Stella kicked-in that hard already?

Interestingly Wiggo sacked his off, and went back to normal ones on his TT bike. Froome still uses these weird ones though. To each their own.

rotor Q rings is another option, not as dramatic as the osymetric but still feel odd for the first few 100km use and "supposedly" remove that "deadspot"

I use standard chainrings and Qrings

do they work? I dunno, certainly feels weird swapping between the two tho

I used to use a biopace ring on the outer, found it to be quite good. Noticeably less tiring.
