New study on non-circular chain-rings.

AFAIK it is this one:
As round as round chain rings can be.

Those graphics are incredibly deceptive. At first glance I thought you were insane, as those were clearly ovalized. Then you look at them for a second and realize they are actually round... Clever of rotor to make it look like more people are using the q-rings.

More clever even is the way they hide that butt-ugly crank with those white graphics!

So I can finally bust out the old BioPace mtb crankset from the 80s?!?

KWalker: Then the picture must be wrong.

djm, check the pictures in the story. These look pretty oval to me.

Interesting that a recent pic of Wiggens has him back on round rings.

I was umming and ahhing about a set of o-symmetrics a few weeks ago.

I wonder if Wiggo has really ditched them, or if he was maybe on a spare bike in the pic? Guess we'll see when Romandie starts.

If he's ditched them or not, I'm impressed with the generosity of the Sky mechanics to put up with those things. Complete nightmare, and I say that as a user and believer of ovalized rings.

At TdR he seemed to be back on them.

His chain came off due to the flat spot on the rings when shifting at the front.

No, it didn't. And they're really not that hard to setup with DA. I've run em and know quite a few that have and its MUCH easier than on a Sram front der.
