Rotor Cranks in Unicycling

[evil-nick]

I saw this on Digg.com today, and I'm wondering, would a system like this be good on unis? It does seem that half the time when I upd I'm in a dead zone ;)

Hmm. I'm not sure.

I converted my BMX cranks into Rotor Cranks by doing dirt jump! :confused: My old unicycle also had "Rotor Cranks" before I snapped it's hub.

I can't say it seemed to be much different once you get comfortable with the odd rotation.

If you want to try it, and have a unicycle with a splined hub, just rotate one of the cranks a few degrees and see what it is like.

If you don't have a splined hub, do a few drops until your hub twists to the desired angle. LOL!

Are you sure the site isn't a prank?

It reminds me of: http://www.classicrendezvous.com/Italy/PMP_main.htm

Insofar as the physics of it, it won't save you any energy.
You may have a smaller dead zone, but you have a less effective "live" zone compensation.
Unicycles are direct drive so your pedal will pass the dead spot on it's own due the inertia of the wheel, so the dead spot isn't really as quite as dead as on a bicycle.

this from someone that didnt complete high school?

ouch!

Lol :D

ouch!

Lol :D
I took all the science classes at once my freshman year. The school counsellor had no control over me whatsoever. I was a rebel nerd. Science is cool. :cool:
I still can't spell very well, and my reading is very slow. There's a price for everything.

I think it would be okay for distance riding, and possibly MUni, but no trials or street or freestyle.
and I just noticed, only one foot will be at all ahead of the other, the rest of the time one foot will be slightly behind...so you'd need to choose which crank arm you want in front.

I think you're all missing how it works. It's not like one crank is permanently ahead of the other. It varies. When the left crank is down, the right crank is just beginning its power stroke, and when the right crank is down, the left crank is beginning its power stroke. In the horizontal postion, the pedals are exactly 180 degrees. It's all mechanically geared inside so the top pedal is ahead of the other one. It's not just a lopsided angle between the pedals. Look closer to see how they work.

Oohhh...well that makes a heckuva lot more sense!! In that case, I think it would be good for distance and MUni, maaybe freestyle, but I don't think it would be easy at all to make one strong enough for street/trials.

the cotterless cranks on my old uni are rotor cranks=P
