But you do know that your education on the subject is limited. I don't need to know whether someone else has a PhD in Biology to know that my high school biology class doesn't make me an expert on biology.

Dude, this is the internet. Are you new here?

One can dream of a better world ...

In my experience, people with more education tend to be more humble and realistic about all of the things they don't know.

Great graphic. I learned something today.

OTOH this is BF and we tend to have conversations where we share our knowledge and experiences with each other. If the answer to these questions is to do research here or on the internet I guess that would put an end to these conversations. And then we would never have met.Think about how sad everyone would be for never having met me.

Ok, so I think I said something similar above, and I'm still firmly in the not a circle camp. But I had a couple of hours of riding time to think about it and yes, the pedal would track a circle if it was orthogonal to the crankarm at all times all the way around, but that is just a special case of keeping the stack from changing the overall distance from the center as the pedal spindle rotates (or rocks), as it travels around, which can be accomplished by locking the pedal from spinning in any position, no?

The conversation already took place. Imagine how useless this forum would become if someone started a new thread about cheap cycling shorts or chain waxing every week. Oh, wait ... never mind.

What, you mean so the surface of the pedal is always at the same angle relative to the crank arm? Like, if it were pedal-top up at Top Dead Center, it would be pedal-top DOWN at BDC?

No, if it's pedal top up, pedal top down, or any other angle, it retains that angle at every position.

This thread is giving me PTSD of Eye Roll’s thread - She Faked It. If you haven’t read it, don’t bother, it’s just as frustrating.

You knew what would happen though.

Right. Which is why the first thing I did when you and others called me out was post a definition that clearly demonstrated I was wrong. Even followed up with some self-deprecating humor.
Not sure why you're still in here punching. It's over.

I don't have the attention span anymore to get through and ponder the OP's question. However, if I lose weight and my butt gets smaller, I have to raise my saddles to counter the fit change.

Or get shorts with thicker padding....

Seems like you are talking about this:



But you wouldn't be able to pedal on such a configuration.

My diagram shows the pedal in the same orientation to the ground throughout the stroke but it doesn't do that in reality.

Yes, or any other orientation that remains constant to the center of the circle, and yes, I'm fully aware that it would be impossible to pedal that. I figured (probably erroneously) that it would help the flat earthers, I mean circle pedalers, regardless of their mathematical formal education level, that the shifting circle center thing just isn't a thing, as any motion of the pedal spindle, which obviously occurs when pedaling, changes the distance between the top of the pedal and any point in the circle, real or imaginary. But alas, this is BF, so....

??? The drawing is clear as it is.

I think the problem is that some people are overly attracted to symmetry. It's a circle because you can pick an imaginary point that makes it a circle. It's a tautology (that is a circular argument).

Note that some people are claiming the center of the crank is an "arbitrary point":

The point was to break you out of your incorrect insistence on the BB center as the center of the circle traveled by the pedal top.

??? I didn't say what you are claiming I said here.

There is no circle traveled by the pedal top.

As others have suggested, you can draw this out on a piece of graph paper and see that the pedal top travels in a circle if the pedal top is always located directly above the pedal spindle.
