Do you really use your 11 cog to go faster?

Whew, what a mess... is this serious?
The rotational speed (tangent vector) does vary with crank arm length, so if you have different crank lengths, then the cadence is still the same, but the rotational speed is different. The pedal on the longer arm travels through a greater distance, and thus a higher rotational speed.

Rotational speed = RPM.
Look, Wikipedia agrees-
Rotational speed (or speed of revolution) of an object rotating around an axis is the number of turns of the object divided by time, specified as revolutions per minute (rpm)
Just sayin'.

You're trying to overcomplicate this.
Rotational speed = RPM.
Look, Wikipedia agrees-
So you stated that "the longer arm travels through a greater distance, and thus a higher rotational speed". We see that rotational speed = RPM, so therefore longer arm = higher RPM.
Just sayin'.

EDIT: I just realized this is all a joke. Carry on.

Does the sprocket (drive) side (larger turning radius) of a wheel hub turn at a slower RPM than the none drive side (smaller turning radius)? If so, why don't the spokes break?

Sure all you need is chainrings on each side. And two different axles, Two chains, cogsets. Dan3333, as we know, is a powerful bicycler. He could probably handle two chainrings easily.

OK, we're at ten pages now. People who don't know any better are going to google "11t cog" and wind up here. They'll try to follow all this, and somebody's going to get hurt.

If using an 11t cog, make sure you use a Z torque crank for max power.
(Apparently somebody with a milling machine, but lacking the most basic understanding of mechanics, thought this was a good idea)

It's for my observation of Festivus Feats of Strength. I already called ahead to the local bike shop that puts on the group rides and asked about riding it that time of year. I have lots of layers of cycling apparel I intend to pack along with me. I can always turn around and ride back down if it gets too nasty. I've been slacking since the time change and I don't know if I'm up for the ride up anyway, but I'm still planning to give it a go. Not counting on setting any Strava segment records.

Word to the wise: If someone seems so stupid that it almost defies belief, especially on BF, they're probably trolling.
@D1andonlyDman @rmfnla thanks for taking the bait, though! Fun times were had by all.

I used to have an 11-23t cassette with a 53/39 crankset. Now I'm 53 and that combination is pretty much pointless. I switched to a 13-26 (Campy 8 speed) cassette and still don't even use the 13t cog very much. FWIW you can still go plenty fast with that combination. I have hit 35mph on flat ground (with a tailwind) and 44mph downhill.

The guy actually had the nerve to try Kickstarter to fund it. Supposed to deliver more power. I think he raised about $20, and got laughed off the internet.
I have seen pictures of a few others from the past century.
If someone wants a heavier, more flexible crankset, then it's perfect.

I want to show up for a crit and spend the entire race running power cranks in this configuration-
I'm pretty sure pushing with both legs at once is a more effective use of power, right?
