maybe more.

but it is ugly in a beautiful way.

What the heck were those engineers thinking? Did they somehow think there was additional leverage from this design? It seems obvious to me, and should have been to them long before these went into production, that the crooked design is effectively the same as a straight crank arm, except weaker, heavier, and more flexible. How do things like this go so far? The bottom line is that the crank arm connects the pedal to the spindle, and it does the same thing no matter the path the arm takes to get from A to B. Stupid.

it might eliminate some of the dead spot on top though. You lose power in the bottom of the stroke, but gain it in the top. So do you really gain anything? Perhaps that what they were trying to do. Then again, I know nothing about physics, engineering or cycling!

Procycling magazine. I can't remember what they are called. Some Spanish outfit is producing them. They were being tested by the Spanish Relax team. They claimed it offered a significant mechanical advantage.

Relax usually rides the Vuelta so you may want to look closely to see if riders are using them.

peaked my curiosity. This is obviously not the same set of cranks I was talking about. The principle and picture look similar. I'll have to go back and try and find the issue.
how could it possibly make any difference?DougSloan
Jul 11, 2002 10:23 AM
Those claims are just plain fraudulent. A crooked crank arm does the exact same thing as a straight one -- it connects the pedal to the spindle. That's all. They could be curved, zig-zag, u-shaped, whatever, but in the end it's still the same. Goofy.

Don't ask me how it works. I'm still confused by the pixels thread.
i know but its cool to see 'things that never made it"Spirito
Jul 11, 2002 11:34 AM
as i see it i think it would only add weight.

if they were pinned behind to several more points one could theoretically say they might be stiffer but i doubt anyone would notice and it would be easier to beef up a straight arm to get a similar theoretical result.

also, the upstroke thing is now beleived to be not that important as most data suggests that there is little point biomechanically in even trying to improve the stroke outside tof the 1''o'clock to 5'o'clock positions.

i just like goofy looking parts - would love to have a campy record hi-lo flange FRONT hub made for east german track teams in the early 70's. how cool is that !!
