Biopace did the opposite of what Q-rings and the ones Froome uses.

You mean use an elliptical chainring to mechanically enhance a rider's pedal stroke?
#facepalm
If you want to be contrary for the sake of being contrary, that's perfect. But we're (more you're, really) derailing the Hot or Not thread for absolutely no good reason.

Now I am going to correct something posted earlier. There is a difference between stomping on the pedals (not the way to pedal) and pedalling by pushing out and down which IS the correct way to pedal. Pedaling circles is not the correct pedal stroke.

Stolen from another website, but I've seen this explanation a number of times...
- The first difference between RotoR and Biopace is elliptical vs. asymetrical.
- The second is the inherent purpose which, as previously stated, is that the Biopace chainrings placed the maximum tooth size at the dead spot while Q-Rings (RotoR) have the minimum tooth size at the dead spot. RotoR claims this is to increase your ability to get through the inefficient spot of your pedal stroke. Biopace is supposed to speed your way through the power portion (less teeth) and use 'stored' energy to power through the dead spot (more teeth)
- Which leads to the third difference which is the adjustable nature of Q-rings (RotoR). Since my dead spot could be different from your dead spot (and would ideally be analyzed with some sort of spin scan) you can adjust where the minimum tooth size sits in relation to the crank arm.

Love my Q-Rings, won't go back to round.
P.S I ride on rollers just fine.

Lets quit talking about rings. We've been derailled (see what I did there...
) Where are some more hot bikes?!

lol, a 643 page thread, with a half of page of chainring talk. I think we'll make it. Post up your bike to get us back on task.

PS Pedaling out and down is not the best way for me to pedal. Not according to the power metre. Pedaling down and pulling back, that's where I get most juice. Furthermore, pushing forward at the top of the stroke is murderous on your knees. Maybe not now, shake hands with 50 and let us know.
No matter how finely some people care to slice it, an elliptical chainring of some sort has come and gone for 100 years now.
Now before someone else says, "yes but early Q rings had a X.XX degree and new Q rings have a X.XX degree and drivel and spleen, do a google search and see if you can find the Shimano chainring that was nearly a diamond.

I enjoy taking the p!iss out of fellows who think they're being smart when they're only being pedantic tinkers.

I blame "the rise of the crabby cyclists" on the change of weather/temps.(I've run into a few as well
)
Suffering on a trainer isn't as fun as doing it on the road.
It gets our chamois in a bunch real quick!!!
