Hot damn! No longer depend on them freaking pesky cogs to decide your gear ratios! I prefer my crank arm to set that for me, thanks.

What if the Hokey Pokey is what it is all about?

Charge $1K, make them out of carbon fiber, and make up a press release saying they will increase your power output by, I don't know, pick a number, say 60% and that they will double your run speed, and you will sell a truckload of those things. I will even conduct the study which will demonstrate that if you take 100 untrained cyclists and have them train on them exclusively for 15 hrs/week for 6 months, remarkable improvements in cycling ability are possible.

If anyone starts asking technical questions, just say they were designed using the polar coordinate system to take advantage of the coriolis effect on rotating objects.

I think they're awesome apart from the name. No upper dead point power curved crank doesn't quite cut it, they need something catchy and short.

I propose "clinton cranks"...

This is the funniest thread in a long time. Thanks guys for making my day. Might as well go home. Nothing is going to top that today !

If there was no financial crisis I would buy them, but hey, I might lose my job tomorrow. How can I afford to spend my last money on cranks instead of beer...

wrong timing to put such a crank on the market.

This is awesome. I am preserving this for all time. The fact you that you believe that these cranks have shifted the deadspot 90deg is baffling to me. Well, not really. But it ought to be. The cranks are no different than if they went in a perfectly straight line. How you've managed to get away with writing that and not getting drilled is beyond me. If this statement is representative of your understanding of either mechanics or biomechanics or both, you're in trouble...

I'm guessing all that means is that they were built with a 110BCD spider. But hey, it could also be a function of the Golden Spiral Ratio...

My comment should have been in pink, but I avoid doing such stuff as I have trouble reading the pink type (not enough contrast) and I would hope that most of the readers here can tell the difference between serious and not so serious posts. The only way these cranks would be different from cranks that went straight might be if they were made of spring steel, such that there might be some storing/release of energy during the stroke. I doubt that is the case.

Chuck Norris could ride these cranks. He's about the only person on earth who could

Wait, I have an idea....who wants to put in some cash for developement and patent attys?

Finally some "proof" that "just pushing harder" is more powerful than pedaling in circles. :-)

They are more awsome than you can imagine, they help acceleration because of the shaped momentum, they littterally pull the crank out of the upper dead curve and the crank arms are bent out from the frame with slightly inverted pedals which allows for more aplied power because you arent pushing straight down and wearing your knees, I read the forums on different sights by so called EXPERTS and couldnt beleive they couldnt see the common sense in this design. I was building a Custom dual shaock MTB and bought 2 sets of these cranks, I combined the MTB version with the Road version and that just created a weapon, I am running 11-28t rear and 42 bio-pace and 56t front on my 18kg MTB, I didnt see the need to add the 3rd chainring as it flies up hill and cruises 55-60kph on flat, I am about to upgrade again to 48t/60t very soon. I will be happy to tell you more.

ITS GO TIME !

The concept of pointlessly making straight things curved worked for Pinarello:

I think what everyone is overlooking is that, unlike Powercranks, these cranks increase the outstanding of your bike. A; Powercranks do is increase the outstanding of your legs. :)

Two things are weird about Sgt. Marshall's post. His FIRST post is in response to a Mar 09 humor post and he has photos of those cranks on his profile page suggesting he believes they work (or that he is being very sarcastic).

Yeah, that's weird. He's either very sarcastic or very fast. Maybe I'll be getting passed by a mountain bike doing 60kph running curved cranks this summer...

I'm very scared.

Duh! Rapp!
Can't you see that they make a 170mm crank into a 200mm. And, the spiral adds a spring effect returning the energy imparted during the downstroke to the horizontal part of the stroke. And, lastly the extra weight keeps the crank turning faster during any dead spots. Hell, you're an engineer aren't you????

I think their theory is that all that metal (read weight) on the right side of the BB will pull the crankarm CW when it's at 12:00, reducing the deadspot there (same effect as if you glued a big weight 90 deg. CW from a normal crankarm). However if the non-driveside arm has a similar curve they just cancel each other out.
